[Qgis-user] QGIS action to run a command in a terminal window on Windows
Hi, I'm trying to create an action to run an SQL on a spatialite database & show the result as a QGIS action. In Linux this works by running a script in an xterm, but I can't work out how to do something similar under widows. Any suggestions?

[Qgis-user] Adding virtual X & Y columns to a QGIS attribute form
Hi, I have created an attribute form for a QGIS layer. I want to add two fields to the form: the X & Y values of a point geometry column. I can't find any way to do this - if I don't use the form, it is easy to add the virtual columns as expressions ($x & $y) in the table view, but I want these in the form view, not the table view.

Hi Krishna, Can you not ask them to turn on the WFS service in their ARC setup? Unless, like many govt agencies, they just ignore users requests. Sigh. Another option is to look for the data you want in data.gov. I have found that govt agencies often have strange & limited access to their data in-house, but also provide their data to data.gov, where it is more accessible.

[Qgis-user] QGIS unable to access Spatialite tables.
Hi, I and a few colleagues are encountering a problem accessing Spatialite tables from QGIS. It does not seem to be happening with v3.28, but it is with v3.34 (in both Linux & Windows). When opening a table in v2.8 there are no issues, everything is working as it has in recent years. However, opening the same table (or an SQL on that table) results in an error message about an invalid layer, but no further or useful diagnostic info. Can anyone suggest a possible cause or solution? My current workaround is to run the select in the Spatialite command line tool, with the geometry exported as WKT & then open the text file in QGIS. At present I'm still trying to get access to the QGIS issues facility to log this problem, so cannot raise this there at present. Thanks...

[Qgis-user] QGIS/spatialite issue - invalid layers
Hi, I have created an empty spatialite database with QGIS via the browser. Running Mint Linux with QGIS: 3.34.1-Prizren QGIS code revision 133927424d9<https://github.com/qgis/QGIS/commit/133927424d9> I create a spatialite table (in spatialite) & add some point data (EPSG 4326 - column is called "geom"). This opens fine in QGIS. I add another geometry column to the table (point, epsg:3994) & populate it with: update station set geom_3994= transform(geom,3994); This appears fine in spatialite, but QGIS tells me it is an invalid layer, but nothing about why... I have been doing this sort of stuff for years & not encountered this before. Can anyone help me sort out why QGIS regards the data as invalid, & how to fix this?

[Qgis-user] QGIS attribute forms question
Hi, I have created some forms for data entry/edit using QGIS. I have successfully exported them & imported them to apply in different computers with QGIS. It can take several hours to create such a form where there are 80+ columns in the underlying database table, I now have the situation where the underlying table needs columns added or removed. QGIS will not apply a saved form to a layer unless the structure is identical. How can I reuse a form for a layer representing a database table with (say) a single new column, by adding the new column to the form, rather than manually creating the whole form from scratch?

[Qgis-user] Null value issue in attribute form
Hi, I have a database table which has an attribute form built for data entry, in QGIS 3.34. There is a text field "station_code" It is set to not null & enforce not null in the form. If the default value is null (empty) the form includes the default text 'NULL'. Any text entered in the form is then appended to the string 'NULL', which is NOT what I want to happen. This behaviour requires the user to delete the 4 chars 'NULL' every time they enter some data, before typing in the value, which is something of an inconvenience, and leads to data errors. If I set the default value in the form to '' (empty string), then the field is populated with this by default, and data entry works as I want, however, as this value is not null, the record can be saved without a value being entered, so the not null requirement is essentially useless. Is there a way to set the form up to have a "not null" constraint applied in the form, without having QGIS pre-populate the field in the form with the string 'NULL'? It works for integer types, the form has an italicised 'NULL' but this does NOT form part of the value in the field, unlike the string field.

[Qgis-user] QGIS & GPS
Gidday and Happy New Year from New Zealand! I have spent too many hours on this already, sigh... Hopefully someone can help. I normally use QGIS with USB GPS units on Linux and don't have driver issues, everything just works. But I now need to re-introduce myself to QGIS on Windows to set things up for other users, and it is proving very painful. I'm using QGIS dev (3.29), 3.22 & v3.28 at present. Same issue on Windows with all of them. I have historically used a Globalsat BR-355S4 USB GPS on Windows with no problems. Just install the Prolific USB-serial driver and everything works fine. My recent Linux work has been using a G-Mouse (U-blox 7) chipset GPS which Linux typically mounts as /dev/ttyACM0 and QGIS is fine with that. Linux needs no additional drivers to be installed for this to work. Now I'm trying to get this working on Windows... I can install the U-blox VCP (virtual com port) driver. The native driver Win10 finds & installs also seems to work, but not with QGIS. I can connect to the relevant com port with several GPS monitoring applications & see the NMEA sentences fine. QGIS lists the port OK, but fails to connect on auto or to the port directly. This is not uncommon with the U-Blox 7, but none of the fixes I have found online have worked for me. I just bought another GPS, a new model Globalsat one, BU-353N5, a replacement for the BR-355S4. This is not sending the $GP sentences, just the $GN ones. My GPS monitoring applications work OK with this on Linux & Windows, but QGIS on both platforms lists the device to connect to, but is unable to connect & use the GPS data. I can't even log the data with QGIS as QGIS won't connect to the port in the first place. My 3 questions: How can I get a U-Blox7 chipset GPS (which is working fine on Windows with other applications) recognised by and working with QGIS? How can I get a Globalsat BU-353N or other GPS that does not output $GPGGA or $GPRWC, but provides $GNGGA instead, etc working with QGIS? Can anyone suggest an alternative cheap, generic USB GPS which simply and reliably works with QGIS on Windows? Is this something that I should file a bug report for (it does seem to be a fragility in QGIS that is not present in other GPS software)? I'm happy to send a working USB GPS to any dev willing to look into this.

Re: [Qgis-user] [QGIS-Developer] Model for Temporal Measurement (vector) Datasets ?
Hi Richard, I think the underlying issue here is that QGIS does not do data management... It just accesses data (whether not managed, managed or mismanaged). You are correct, the traditional GIS model of a feature with attributes does not map to the real world very well in many use cases, and timeseries data is one. GIS is seldom used to manage data these days, with very powerful spatially enabled databases readily available. To use your IOT approach where location is just an attribute, in a relational db, the location IS just another attribute. Unlike the GIS model, where the spatial feature is somehow different, here it isn't. A record can have multiple geometries, times, dates, strings, numerics, etc... like start time, end time, start location, end location, trackline between them, if you want... impossible without nasty hacks in a GIS centric data store. So you have a pretty standard situation where you have a set of sites where data is captured in an ongoing basis. I have designed Postgis databases to do this... most recently, when Postgres/Postgis was staring to slow down a bit with 600,000,000 readings I moved to Postgres/Postgis/TimescaleDB which is returning typical query results in 10's of milliseconds with 4 billion readings. You don't just have sites with readings, you have sites, sensors, calibrations, instruments, readings, personnel, etc... there is a whole lot of metadata/data pertaining to your setup that should probably be managed in a database. I don't know if you will have enough data to justify using TimescaleDB, but you should be using some sort of db to manage your data effectively & efficiently. And Postgis/Postgres is a hard combination to beat as a tool for doing this well. Then you point QGIS at your database for the mapping, cartography, visualisation, etc. You can use database views to simplify queries, but there are issues with QGIS and views. I find using the QGIS DB manager with a query instantiated as a QGIS layer works much better than accessing a view in many cases. And for an alternative mapping of IOT data to a data model, the Object Relational approach provided by Postgres supports non-relational structures like key/value (hstore) or jsonb data storage. 52North have a (somewhat complex) Postgis database design to provide a data store for their SOS (Sensor Observation Service) software. Perhaps overkill for your use case, but a very complete and robust solution. See: https://www.researchgate.net/figure/The-52-North-SOS-schema_fig14_327124727 Hope this helps, there are certainly effective ways to do what you want out there.

But in the IOT world the 'location' is 'just an attribute', and the 'other' data is actually more of interest (and growing in time). Currently to view measurements, 'we' often replicate the location for every value/measurement: we create a 'Feature' for every time step (eg for example via a WFS) The OGC has a SensorThingsApi (STA) standard, in which for given location you can request all values/observations (of filter a certain sensortype/parameter). So one geometry has a full table of data to it. BUT to 'work' with that data in QGIS, you always have to 'flatten' it, one way or another, (I think), for every time step: create a feature with: location, time, value... My Question: - isn't there some model (or can we come up with one) in which a location can actually have a range of time/value data (like some table join like), and when you use the Temporal Controller, you style your layer by RE-using the one location, but getting the value for current Timestamp (in the TimeController). Some sort of indirect filtering? - or is this the mesh model (I know netcdf's in which you have often predefined meshes/location and the data/time vector is growing)? And would a solution be to have some kind of in memory vector -> mesh loader or so??? I hope this makes sense to others. Any input appreciated. Regards, Richard Duivenvoorde PS, if you want to play with SensorThingsApi: - install: https://github.com/AirBreak-UIA/SensorThingsAPI_QGIS-plugin - connect it to: https://airquality-frost.k8s.ilt-dmz.iosb.fraunhofer.de/v1.1/Locations (around 5000 location and 500-million 'observations') - load all locations in one layer, and click on a location My point: the data is then viewable/selectable by table and graph, but NOT loadable in

This particular one is now filtered out for 3.26+, as it's not reflective of a bug in QGIS. The others still remain, as they likely ARE indicative of something which needs fixing in QGIS.

Re: [Qgis-user] Polar stereographic (0 - 360 longitudes)
I don't believe you can. The underlying proj libraries (as used by QGIS) no longer support longitudes > 180 by default, so any re-projection from EPSG:4326 will only work with +-180 longitudes. There isa command line parameter (+over) which can be used with proj on the command line but I don't think this is supported by QGIS. If you use Postgis (or Spatialite), there is an ST_ShiftLongitude() function that will switch +-180 to 0-360 or the reverse which makes the operation pretty trivial for any sort of geometry. I have created a custom QGIS/Postgis projection (many years ago) which I assigned a code of 4327, this was essentially 4326 in a 0-360 degree space, so I could reproject between them, I'm not sure if this is still possible with the latest versions of proj with wkt definitions.

Re: [Qgis-user] RAM and processing speed requirements for QGIS
Hi Helena, My 02c - it totally depends... QGIS as an application does not require much memory or cpu, until you throw data at it and ask it to do something. Your data and tasks determine the requirements, not the bare application. I did some benchmarking a while ago - R requires up to 8x the memory to load the same vector datasets as QGIS - so at least compared to R, QGIS is very memory efficient. Also - QGIS has no data management capabilities. If you want to manage your spatial data on the same computer, you will probably want to install a spatial database, which will run in parallel to QGIS. So having the resources to do this will help a bit. A dual core cpu is not good for parallel processing - two few cores to be efficient. That said, a reasonable i5 cpu with 8Gb of memory is plenty for basic tasks. More is obviously better. An older 2.7Ghz i5 is probably minimal, i7 a bit better. Before spending on hardware, try it and see. If your system performs well enough for you, that is really all you need to know. If not, fire up the system diagnostics & see what your memory & cpu (& possibly disk) bottlenecks are to see what you need more of. Personally, I find the best general purpose platform to install & run QGIS on is Linux. If you are into cartography and the Adobe tools to work with graphics, then a Mac. Windows only if you don't have a choice.

Re: [Qgis-user] Rounding off QgsPointXY
I'd suggest managing your data in Postgis. Adding a rounded geometry to your dataset becomes a pretty simple sql (assuming your data is lat/lon - just change the SRID if it isn't): alter table mydata add column rounded_geom geometry(POINT,4326); update mydata set rounded_geom=ST_SetSRID(ST_MakePoint(round(ST_X(geom),2),round(ST_Y(geom),2)),4326); line 1 creates the new column, line 2 populates it with new points with coords set to the rounded coords of the original. You still have the original to compare. Or you can drop it, as you prefer. QGIS & Postgis make an incredibly effective suite. Postgis enables not just data management and query capability, but substantial spatial analytical power, QGIS provides visualisation, as well as additional analytical tools.

Re: [Qgis-user] On the capabilities of QGIS
Hi Jennifer from West Island, from someone else from down under. I'm not sure this is a simple exercise, or that you'll get any better precision than 0.3%, but... I'd grab any reasonable world map dataset, natural earth, GSHHG, etc... https://www.naturalearthdata.com/ http://www.soest.hawaii.edu/pwessel/gshhg/ Also look here for other data: https://www.justmagic.com/GM-GE.html https://argo.ucsd.edu/data/data-visualizations/marine-atlas/ Info on ship locations is pretty widely available from sites like: https://www.vesselfinder.com/historical-ais-data#position_data for data on territorial seas, EEZ's etc, to refine your area calculations: https://marineregions.org/downloads.php Open the coastlines in QGIS. Create a new, empty polygon layer, and make it editable. Draw new polygons covering the regions you'd want to deploy the buoys. Up to you how precise they are. Remove (difference) any EEZ or territorial sea regions you feel appropriate Get the remaining cumulative area of the polygons. I think there are plenty of guidelines on how to do this sort of things, or feel free to contact me direct if you have questions. Current & wind info is around - see the tracks of ARGO floats as one case in point But note: 1. The bouys would need to NOT be a hazard for shipping. 2. Controlling stability (direction of reflection) could be problematic. 3. The reflected light would need to NOT be a hazard to overflying aircraft. And a question - why would these mirrors only be deployed at sea? The warming is happening to land as well. Surely there are substantial areas of land that could be used in the same way with minimal ecological or social damage - thinking of Australia, Africa, South America, Middle & Far East. Like carbon credits - set up solar reflective farms to offset climate change. Cheers Brent Wood G'day there, all, QGIS just discovered. Oh. Wow. Jennifer of Chermside Oz here, with two questions of a very generic nature. Sorry. Before I commit a big slice of my remaining life-span trying to mistress GIS via Q, can I ask: 1/ is Qgis in tandem with any known DB capable of providing me an accurate fine-grained result on the area of just the oceans, all of them, 360° round, that lie between the ancient Greeks Tropic zone, in my case either ±45° lat or ±50°. It's the granularity that I need. (2° grid good, tighter ideal.) 2/ if Yes, what would be your rough assessment of the time it would take for this tech-head, in Mac since Syst 0.9 ancient crone, who is not fluent in any code or language to pull out an answer, or 3/ again if Yes, and faster, is anyone willing to give this poor pensioner (cue the strings & harps) a price on your digging out this data? This because I believe that after 20 years of head scratching after the shock of first seeing the 200 year plot of CO2 in the atmosphere, and being an old radio tech recognizing a +ve feedback curve, think that with my 5th concept (four failures) I've gotten a winner that should stop ocean heating. Reflecting enough incoming insolation back out to level the EEI, and perhaps even reversing the heat build up. All done with 98% reflective buoys launched at strategic points onto passing currents, so they stay mostly in the Tropic zones. I need a scientifically valid referable source of accurate areas data to calc how many bouys are needed. All CC & open source, so not much followup cash flow. Hope someone can see a solution. Short of measuring my old 300mm inflatable home globe! Google Earth has proved accurate to establish gross areas (+0.3%, my measuring, 10° x 10° grids.)

Re: [Qgis-user] Qgis-user mailing list
You should be able to intersect the two layers, but may have issues if they are in different CRS's, or there are topological errors present. If they are in different CRS's, then export one to the CRS of the other, and generate the intersection with that one. Also run Vector-> Geometry tools -> Check validity on each source layer to ensure the data is valid. The result should be a layer that has all the polygons from one split by the other to form new polygons common to both layers, and with each of the new polygons having all the attributes from both original layers. Note that if you need to include the areas in the source layers that are not common to both, you'll need to get the differences between the layers (both A-B & B-A) and add these to the intersection. Note that this is essentially a spatial data management question, and while QGIS can do it perfectly well, I find it can be easier to manage the data in Postgis tables in a database, and use Postgis SQL statements to do this, using QGIS to see the resulting data in the map canvas.

Re: [Qgis-user] Vote for Lat Lon Tools Default Coordinate Order - YX or XY
1. "lat/lon" is the world wide order for degree based maps (esp in the navigation space) 2. "Lat Lon is the name of the tool, It doesn't make any sense (to me) to have lon/lat as the default order for this tool. I know some other GIS tools use lon lat to be consistent with northings & eastings which are XY, but with this tool being all about lat/lon, I figure that is how it should be. One option - if you are really concerned about this. Prompt on first use to set the user's preferred default? Make it impossible for the user to use the plugin without having first chosen what they want the order to be. So it doesn't have a default, just a user selected order.

Re: [Qgis-user] Historical data in QGIS-PostGIS
I think this is straightforward, if I understand you correctly... Assuming each year comprises a separate version of the data, have the year as a column in the table, which allows you to select by year, group by year in the database, on an indexed integer value, which is very fast. In terms of displaying as layers in QGIS, there are two approaches which should work, which one is better is something you'd need to work out for your use case: 1. Open the table, apply a filter for just the desired year(s). Rename the QGIS layer as the year(s) to avoid confusion later. Apply whatever symbology you desire. Repeat for each year (or set of years) that you want to plot. This gives very good control of each year (set) of data as a separate layer, but can be complicated with many years (layers) of data. 2. Open the table and set the layer symbology to categorised, then categorise by the year column. You have a single layer, but can set the symbology for each year and turn individual categories (years) on/off as desired. Not quite as powerful as completely separate layers, but much easier when you have lots of categories. I'm not sure how much data you have, but if you have 100's of millions of records, using Postgis to manage geometries, Timescaledb to manage timeseries data and hstore or JSONB to manage multiple readings per sample (depending on just what your data are) can give huge space & performance benefits. (I have just done this with a sensor dataset of 1.2b readings) Something else I have done that you may find useful. You can write R functions to use as SQL using PL/R. This means you can select data & generate a plot directly from Postgres SQL - just run the SQL & then look at the output graphic. If you have the image open & generate a new graphic via SQL, at least on Linux, the image viewer recognises the change & refreshes the screen. This is MUCH easier & faster than any other way I have tried to visualise my data directly from a database.

Re: [Qgis-user] Show multiple photos attached to one feature
Hi Sophia, I suggest you set up a QGIS Action on the layer to view the images for a feature. For a single feature, your data needs to contain a field with all the image names space separated (so no whitespace within names unless you want to make life difficult!!). The action will be a batch file (Windows - painful, or Powershell) or script (Linux/Mac - easy) concatenate the path to each filename, then open each file with an image viewer. eg: a point feature has this text as a field (called filename): P1010005.JPG P1020700.JPG (the names of two pictures associated with the point feature) I write a simple shell script (I'm on Linux) to iterate through a list of files (I called it open_images): #! /bin/bash # # iteratively opens images passed on the command line # FILES=$@ for FILE in $FILES ; do eom /home/baw/Pictures/$FILE done The bash script sets the "$FILES" variable to store the list passed on the command line ($@) It then uses the eom program (simple Linux image viewing program) to iteratively open each file in the list, prepending the path to the file for each one. In QGIS, I create an Action on this layer called "open image", it contains the command: /home/baw/qgis/open_images [%filename%] This is the path to my my script, followed by the list of image names. So, if I then select the action tool in QGIS, when I click on a feature on the canvas, QGIS runs the command as set up in the action, which is my script. It passes the contents of the "filename" field for the feature as a command line parameter. (essentially runs the command: /home/baw/qgis/open_images P1010005.JPG P1020700.JPG The script then shows the first file, then the second, etc. whenever you click on a feature in QGIS. You can have a list with as many images per feature as you like (within reason... 3 might be a problem!! Hope this helps, I find the Action tool very useful for this sort of thing. Not quite as easy in Windows, which is not primarily a command line setup, but can still be done.

Re: [Qgis-user] how show themes from single polygon having rainfall time series data
One way that might work for you, see the QGIS action tool. Create a system invoked R script that plots the time series for a specified polygon, taking the polygon ID as a parameter on the command line. Then create a QGIS action that invokes the script & passes in the polygon ID. I have done something similar with Postgis/QGIS & R - the R function was embedded as a PL/R function inside the database, so the SQL generated the plot of the data (rather than just retrieving the data). The SQL created the plot & returned the filename of the plot it just created. This worked on both a web site & from QGIS (QGIS on Linux & Windows both worked, but the script was a bit different on each) HTH, Brent Wood Brent Wood Programme leader: Environmental Information Delivery NIWA DDI: +64 (4) 3860529 From: Qgis-user on behalf of shrawan tripathi Sent: Monday, March 23, 2020 08:12 To: qgis-user Subject: [Qgis-user] how show themes from single polygon having rainfall time series data Hi, I want to show rainfall distribution for a time series for a single polygon, is it possible? if yes please let me suggest. -- Warm regards Shrawan Kumar Tripathi [https://www.niwa.co.nz/static/niwa-2018-horizontal-180.png]<https://www.niwa.co.nz> Brent Wood Principal Technician - GIS and Spatial Data Management Programme Leader - Environmental Information Delivery +64-4-386-0529 | National Institute of Water & Atmospheric Research Ltd (NIWA) 301 Evans Bay Parade Hataitai Wellington New Zealand Connect with NIWA: niwa.co.nz<https://www.niwa.co.nz> Facebook<https://www.facebook.com/nzniwa> LinkedIn<https://www.linkedin.com/company/niwa> Twitter<https://twitter.com/niwa_nz> Instagram<https://www.instagram.com/niwa_science> To ensure compliance with legal requirements and to maintain cyber security standards, NIWA's IT systems are subject to ongoing monitoring, activity logging and auditing.

I've been using QGIS since v0.2, and running QGIS training workshops annually for several years now. While the new capabilities are great, I find users are frustrated in that they have difficulty keeping up - no sooner do they become comfortable with a version & they need to upgrade. People coming on my workshops are running various versions, and so some things work & others don't. I run 3.4, 3.10 (& still 2.18) as well as the nightly builds at times... so appreciate the benefits & issues of the current situation.

Aside from a few quirks (e.g. dependency issues on Linux), I've always liked the QGIS release cycle so I'm coming from that perspective. To add to Alexandre's explanation, this is usually how I explain QGIS releases: There are 3 branches of development - LR (Latest Release), LTR (Long Term Release), and nightly builds. Let's take a look at the LR and LTR branches. I usually take "maintained" to mean that the branch is actively developed -- bugs will be fixed, new features are added, etc. The LTR (now 3.10.3) is maintained until the next LTR (in 12 months when 3.16.4 becomes the LTR). During those 12 months, a PR (Point Release) will be released for the LTR branch each month (named 3.10.4, 3.10.5, ..., 3.10.14). This PR includes the bug fixes for 3.10.X. Being an LTR means that there (usually) won't be any changes that will break that version in 1 year. This is usually why people think of LTR as "stable". The LR (now 3.12.0) contains the most recent features of QGIS. A new LR is released every 4 months. The next LR (3.14) is slated to be released in June 2020, the next after that is 3.16 in October 2020. The 2nd LR released after the release of the LTR is the version that will become the next LTR. In this case, the 3.16 version that will be released in October 2020 is slated to become the LTR after 4 months (e.g. 3.16.4 will become the LTR by February 2021). For each month, a PR is also released for the LR branch until a new LR is released. For example, there will be a 3.12.1, 3.12.2, and 3.12.3 releases for March, April, and May 2020 until the 3.14 release in June. This repeats for 3.14.1,..,3.14.3 until the 3.16 release in October. Throughout the year, there can be big changes between LR versions (e.g. between 3.12, 3.14, and 3.16) as compared to the LTR which stays at 3.10.X. It's also worth noting that useful features in the LR branch can be backported (added to) the LTR branch. The "LR/PR" released every 4 months denotes that the release is a new LR. The "LTR/PR" released in October denotes that this release will be the next LTR. It is not put in the LTR repo until 4 months later (February) where it officially becomes the LTR. We can also think of it this way: For the LTR branch, you can expect updates every month of its life (or with every point release) with 3.10.3, 3.10.4, 3.10.5, ..., 3.10.14 but these will usually be minor and not so drastic. Meanwhile, there may be drastic and major changes between LRs like 3.12, 3.14, 3.16, etc. but only minor changes between PRs of the same LR -- eg 3.12.1 and 3.12.2, 3.14.1 and 3.14.2, etc. I also agree that the road map found at https://www.qgis.org/en/site/getinvolved/development/roadmap.html<https://aus01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.qgis.org%2Fen%2Fsite%2Fgetinvolved%2Fdevelopment%2Froadmap.html&data=02%7C01%7Cbrent.wood%40niwa.co.nz%7Cdf484ed7b9284ad3254508d7bd9af506%7C41caed736a0c468aba499ff6aafd1c77%7C0%7C0%7C637186345604237900&sdata=VK6ZNQWbKIOODtsJ04mS5FTZhF8Nyz4AGCUgo5shC54%3D&reserved=0> is geared a lot towards dev people but, in its defense, it is located under the "Get Involved/Development" part of the documentation.

Re: [Qgis-user] (no subject)
To add a point, you need to create a new empty point layer and make it editable, so QGIS has somewhere to write the points to. If you already have a layer to add to, then open that & make it editable instead of creating a new layer. If you are digitising features, you might also enable the digitising & advanced digitising (if appropriate) toolbars. (View -> Toolbars on the main menu bar) A DXF has vertices defined by coordinates. You need to tell QGIS what coordinate reference system these coordinates use. In general, there is a welth of help for this stuff already out there - Google is your friend (in this case :-) If you google for "how to add points in qgis" there are on line videos, tutorials, etc... should provide all you need to know... The same applies to almost any task in QGIS, that is how I justy found a plugin you can install, just click on "Plugins" and once QGIS had downloaded the list of available plugins, search for DXF to find "Another DXF Importer / DXF2Shape Converter" Hope this helps Brent Wood Programme leader: Environmental Information Delivery NIWA DDI: +64 (4) 3860529 [cid:imagee98db1.PNG@c26a15af.47bdbe75]<http://www.niwa.co.nz> Brent Wood Principal Technician - GIS and Spatial Data Management Programme Leader - Environmental Information Delivery T +64-4-386-0529 National Institute of Water & Atmospheric Research Ltd (NIWA) 301 Evans Bay Parade, Greta Point, Wellington Connect with NIWA: niwa.co.nz<https://www.niwa.co.nz> Facebook<https://www.facebook.com/nzniwa> Twitter<https://twitter.com/niwa_nz> LinkedIn<https://www.linkedin.com/company/niwa> Instagram<https://www.instagram.com/niwa_science> To ensure compliance with legal requirements and to maintain cyber security standards, NIWA's IT systems are subject to ongoing monitoring, activity logging and auditing.

Re: [Qgis-user] QGIS Live GPS Tracking Settings (QGIS 2.14)
Hi Malhar, I'm currently looking to fund a QGIS developer to add the ability to (optionally) save the GPS timestamp along with the point feature. If you also have work you'd like done in the GPS panel, I think we could perhaps save costs by collaborating on a single upgrade for all our desired functionality? Please contact me if you are interested. Note that you can sort of achieve your goals by recording the GPS data directly into a database (rather than a shapefile or non-RDBMS dataset). Then plot the data from this table instead of using the live GPS display. You can then open a layer which has a SQL something like: select * from table where timestamp > now - interval('10 minutes'); Then use the capability described here for that layer: https://github.com/qgis/QGIS-Documentation/issues/1683 This gives you the last 10 minutes data - or any interval you want, refreshed automatically as required To use an SVG symbol such as an airplane for the current position, you can create a new point layer with a query like: select * from table where timestamp = (select max(timestamp) from table); This will always return just the latest point feature... and if the timestamp is indexed, it can do it pretty quickly. Assign a suitable airplane symbol to the layer and set this layer also to redraw automatically. Then assign the label for this point layer to be built up as a string with deg/dec min, then the latest position will always be written on the map in the format you want. This would work with any of the 3 main open source spatial SQL databases (Postgis, MySQL/MariaDB/Spatialite) as it uses very standard SQL statements. I have done similar things in the past with Postgis & Spatialite. A lot of these sorts of issues can be treated as layers plotting subsets of data filtered & reformatted as required - so they become data management problems rather than live GPS data problems, and normal database functionality can be used to provide the required capabilities. Hope this helps!!

Re: [Qgis-user] What Plug in does live GPS input in QGIS?
HI, The QGIS panel allows you to manually save individual GPS points to a currently open & editable point layer - a mouse click on the button does this. Upon saving a point, you will be presented with a dialogue box to enter the values for any fields (attributes) defined in the map layer. There is also a check box in the pane to log the NMEA GPS data to file. You can then use a Python QGIS NMEA plugin (nmea2qgis2) to open the saved GPS NMEA data file, and optionally save as a shapefile. This is an experimental plugin, so you will need to enable these. I just used this plugin today - and found a bug in the python code which incorrectly converts southern hemisphere latitudes to decimal degrees, but this is a simple fix, & I'll email the author to hopefully fix the code. Prior to this I used an awk script to convert the GGA lines in a QGIS GPS log file to points, with a counter allowing them to be ordered and easily turned into a line by another QGIS plugin (Points2One). Hope this helps...

Re: [Qgis-user] GPS Live Tracking Problem
Hi Don, I use this regularly, but I save specific points by clicking on the plugin to do so. I do not normally save the track. I have a few suggestions... You are correct, the displayed track is not normally saved, but I think you can tick the box to "Automatically add points" to save the points along the track. I'm not sure what the "automatically save added feature" does, but it is probably worth trying. If you set QGIS up with an open & editable point layer, you can use the GPS panel to save points there, for each point QGIS will prompt you to fill in the attribute values before saving...

I own a commercial farm and have used QGIS to develop a property map with layers containing roads, trails, fields, buildings, etc. I would like to use my IPhone 8 as a GPS receiver to track movements live and have them appear digitized on a designated map layer and saved as a line feature on that layer. I would also like to establish waypoints this way as well. The documentation indicates that this is possible, but I'm having trouble and would be grateful for some help. I'm using QGIS 3.2.0 Bonn. I'm running Windows 10 Home, 64 bit, on a Dell Latitude E6520 with 8 GB of RAM. Per recommendations I found in the QGIS documentation, I'm using GPS 2 IP installed on my phone to enable it to send GPS data to my QGIS software. I'm using the "GPS Information" panel in QGIS as directed. I have successfully established a connection between my phone and QGIS. Per some instructions I found in the QGIS documentation regarding Live GPS Tracking, I created a new vector line layer (Shapefile type) and enabled editing for that layer and highlighted it in the Layers Panel. I then traveled around the property and, as hoped, a line was created on the map live as I moved. At the completion of the route I attempted to save changes. However, this is where I encountered the problem. What I noticed first was that the line created by the GPS track was not "attached" to any layer. If I unchecked all layers, the line was still there on the white map canvas. And I could not get rid of it unless I closed and re-opened QGIS...at which time it would go away. On the other hand, I cannot save it either. It does not appear to be attached to any layer nor can I save it the layer I created or any other layer. I've tried deleting and creating a new vector layer, but I get the same results. Everything seems to be working to get the track into QGIS, but I just can't get it associated with and saved on a layer. I'm very impressed with QGIS and our property map has already been a valuable tool for us. This GPS tracking ability would be very useful and I would very much appreciate any help. Thank you in advance for you willingness to help a beginner.

Re: [Qgis-user] Simple methodology for user / data / map interactivity?
Sort of in the area you are asking about: See the Action tool Under Windows this can invoke a batch file to display the result of an sql for data about the (Postgis) feature clicked on. Even easier under Linux with a bash script. If one of the fields is an image file, you can create an action to display the image associates with the feature. A useful bit of functionality... But to do exactly what you are asking, I think the Attribute table does this, so it is a matter of explaining the steps to your users, rather than writing code... If you select a set of features in a Postgis (or most type of layer) layer rendered on the map, QGIS highlights the selected ones as defined in the project properties. Open the Attribute table for the layer, you will see the selected features, not only highlighted on the map, but also in the attribute list. Click the "move selected features to top" button, and the selected/highlighted features will always be at the top of the list. The attribute table has buttons at the top to zoom & pan to selected features...

I would like to use QGIS as a visual / interactive front to somePostGIS data and am not sure what the best route to doing so is. Happy to explore further myself, but wanted to get some input on what needs to be joined up to get started on building a little process. Basically, if I wanted to present a map of features and have a button (like the attribute information one) which a user would click then use to select features, I want this to run a SQL query which to get related features for example and highlight them on the map view, possibly pan to the extent of the newly selected feature set. Does this sound like a plugin – or would that be taking things too far? Would the best way for the dynamic layer to be setup, to be a view – empty except when populated by the query and styled to be dominant over the full set of features? As a simple example, say I had a district zone system of polygons and I wanted a user to be able to click on any polygon, and have all the neighbouring polygons highlighted, centred and fill the map view as fully as possible.

Re: [Qgis-user] QGIS vs ArcGIS in Education and Practice
Hi, I agree that most "GIS jobs" are after ESRI expertise. However, I think you have answered yourself - many universities offer GIS classes. Based on donated ESRI software to create market dominance. Many other disciplines, especially in environmental science also run GIS classes with a focus on their discipline. These typically use QGIS & open source as they are not the beneficiaries of ESRI marketing largesse, and open source provides the required functionality within budget :-) So - if you want to train GIS professionals, ESRI does make sense, if you want to train (say) ecologists in using GIS for ecology, use QGIS. If you want a more solid grounding is GIS, & spatial data analysis, modeling & management, teach a suite comprising QGIS, R & Postgis. Another aspect to consider, in the third world, especially African & Pacific Island nations, QGIS is the preferred platform. Generally only in the first world, and often just western nations, is commercial GIS software a popular choice.

The rest are going to get enough basic skills to use it if their job requires it, but it isn't their passion. I have been arguing the QGIS is more affordable and accessible, but learning two or more applications complicates things. Do I have them repeat things they already know how to do in one application in the other? Do I teach certain skills/techniques in one platform and others in the other platform? Ideally I would like to teach them how to evaluate and select the application that they like best for a particular project, but how do I do that? Most QGIS users seem passionate about open source, and tend to avoid ESRI products if at all possible, in my experience. But most gov. jobs in the U.S. still say must have experience with ArcGIS.

To put it bluntly, I think ANY GIS practitioner who can only list experience with a single application (or vendor's suite) on their resume is not at all competitive in today's market. There's enough free open source or trial software available that it really shows a lack of motivation for someone not to have skills in more than one application.

Some minor ports may take someone a while to complete - & others need not be waiting on this. A QGIS release announcement is NOT a promise that every OS out there will have a new package ready to go at the same time...

I believe the wider user community are incredibly well served by both the devs & the packagers (as a user of Windows, Ubuntu (dev version) & OpenSuse packages) and would like express my appreciation here!! If a packager has not built you a package when you want, compile it from the new source - that is what open source is fundamentally about. Though personally I, being lazy & not a dev by any means, just wait for the package except on Ubuntu (actually Mint) where my desire to play with the bleeding edge is enabled by the the nightly dev build - a wonderful resource!

Re: [Qgis-user] Assistance with high-level use case of QGIS for commercial use
Hi Dave, If you don't require any desktop mapping, just a web accessible spatial overlay operation, I'd have thought using Postgis to store your polygon layer(s) & to carry out the overlay operation, then return the txt file would be simpler & easier, via any sort of scripted web interface. the sqls for the overlay to return the text file could just about be as simple as: copy feature from txtfile; select f.id, f.lat, f.lon, p.id from polygon p, feature f where ST_Contains(p.poly, ST_SetSRID(ST_Makepoint(f.lon, f.lat),4326)); drop feature; The first loads the text file into a database table - at potentially 10,000's per second... The second creates a point geometry from the point coordinates, sets the coordinate reference system for this to lat/long, and returns the point values as well as those of any polygon on your polygon dataset which the point lies within. The point table is then deleted. You just need to wrap this up in your preferred scripting language to make it web accessible.

Their fee to deploy a mapservice has opened my eyes to other options. I use the term mapservice loosely because what I want to deploy won't even have a map GUI. It is quite simple actually:I would like to deploy QGIS such that multiple non--GIS users can use their individual secure logins to upload a .txt file (in a prescribed format) which will contain a feature ID, latitude and longitude coordinate for each row. Then in batch mode, the program would then overlay the points with a polygon layer I maintain on that server. The output would be a .txt file containing the input attributes plus 1 attribute added to each row from the polygon layer. No map display needed, no other user interaction. This is a simple geospatial operation for which they will pay a nominal fee.I was able to do this same operation manually with QGIS desktop and I see there is an API to perform the operation as a script. So...are there any barriers to me doing this with QGIS/QGIS Server? Is there support for this use-case already?

[Qgis-user] Relations capabilities
Firstly, thanks to those who already helped me with this. I have established a relation between non-spatial catch records in a postgis table and a table of station information (linked via foreign key). If I click on a station with the info tool, I can see the various catch records from that station - so the relation is working. But that seems to be it. If I filter on the species in the catch, that only applies to the catch data showing up when I select a station - it does NOT hide stations where that species was not caught. I cannot change symbology based on a relation, I cannot select features based on a relation - all I can do is view the records - and with 70 fields in the station layer, the catch records are just a small window at the bottom of the form.

Re: [Qgis-user] information
Hi Gill, QGIS needs to know exactly what CRS the data is before it can convert them to something else. The EPSG code is normally how you do this. If you see:http://spatialreference.org/ref/?search=irishthere seem to be 6 possibilities. I'm not sure what the difference is, but you should identify the correct EPSG code for your coordinates. You can then (in QGIS with the dataset opened as a map - have you got that far?) right click on the layer in the layer tab to bring up the layer menu, & use the "Set layer CRS" facility to tell QGIS this (if it does not already know - in some cases it may have read this from the data automatically). There are now 3 ways to "translate a long list of Irish grid references to a map which has lat and long data" depending on exactly what you mean. You can then go to Project->Properties to set the QGIS map to EPSG:4326, which is basic lat/long coordinates. This will tell QGIS to display your Irish grid data as lat/long - ie: reproject on the fly to provide you with a lat/long map. You can use the layer menu to save your layer, in a different format and/or projection as you specify. If you change the output CRS to EPSG:4326 & save it, the new dataset will be have lat/long coordinates. This creates a new data file (rather than a map), as a lat/long version of your data. In the Print composer, for setting up a map layout for printing, you can have a map in (say) Irish grid coordinates, but set up labelled ticks on the map frame which are in lat/long. You can also choose to use decimal degrees, degrees with decimal minutes, optional NSEW suffixes, etc. This gives you a locally projected map labelled with degrees. I hope this helps, Cheers Brent Wood From: Gill Weyman To: "qgis-user@lists.osgeo.org" Sent: Friday, February 19, 2016 11:51 PM Subject: [Qgis-user] information HelloI am new to qgis and wondering how I translate a long list of Irish grid references to a map which has lat and long data?

Re: [Qgis-user] adding points within polygons
Which version of QGIS are you using? This is in the dev version which I'm using (on Linux), but not in QGIS 2.8 (just looked at that on another laptop - Geometry tools is there - but not the centroid one). I don't know if it is in 2.12 or not. You can also install the "realcentroids" plugin. This seems to create a replica of the polygon table, but creates a point feature to replace the polygon, which should also do what you want. I just tried it & it worked in a simple test case. Perhaps your easiest option. There is also a processing -> qgis geoalgorithms -> polygon centroid function, but this can return a point which does not lie within the polygon if the polygon is concave. A bit more cumbersome - but you can also: edit the polygon layer, open the attribute table start the field calculatorcreate a new (real no with decimals) column as the X value ie: X($geometry) create a new column as the Y value ie: Y($geometry)save as CSV file open the CSV file & define it as a point layer using the new X & Y columns for coords You now have a point layer of centroids (but note that centroids can lie outside a concave polygon):-) Cheers Brent From: rsweeny To: Brent Wood ; "qgis-user@lists.osgeo.org" Sent: Tuesday, February 9, 2016 7:54 AM Subject: Re: [Qgis-user] adding points within polygons Brent So kind of you to respond.

Re: [Qgis-user] Adding Points by Coordinates
Hi Grant, You can add a text file (delimited text layer) of points pretty easily (the comma icon or from the layer menu). Then just edit the text file with your favourite text editor. I suggest you create the file first, then open it in QGIS. Specify the field delimiter, if the first line has column names (usually a good idea), the CRS, which columns to use for X & Y coords and tick the "watch file" box to refresh when new lines are added. No real need to build such a tool into QGIS when this works so well.

Re: [Qgis-user] postgis/gresql views
Hi Matt, What is the actual SQL you use to create the view?Something like:create view v_geo asselect tab1.location, tab1.zone, tab1.date, tab1.value, tab2.geomfrom tab1, tab2where tab1.location=tab2.location; Then do a select * from v_geo order by location, zone, date; To check the records are as expected, before you try to open in QGIS. Also note that ideally you should include a integer primary key to clearly identify each record uniquely. eg: alter table tab1 add column id serial primary key;and include this id column in the view. You have not described the relationship between zones & locations. My assumption would be that locations are point features & zones represent polygons that the locations lie within, but this doesn't make sense with your example - "for all zones in location" It is also unclear whether you want to view categorised data in QGIS, or create Postgis views in Postgis from QGIS:"Ideally I'd like to be able to create labels and views from within qgis ..."

Re: [Qgis-user] Fwd: QGIS hardware recommendations?
Hi, The general answer is as much and as fast as you can get - cpu, memory & disk. Depends as much on your expectations, patience & workload as anything :-) If you are working with lots of data, memory & disk, anything analytical, cpu - and note that reprojecting on the fly counts as analytical :-) I'm doing pretty well with ex-lease Dell E6420 laptops. They are now being sold cheaply - 3-4 years old but are well built & came with a 3 yr warranty when new so are not the cheaper 1 yr warranty home & student systems the big retailers sell. Typically good I5 2.6Ghz cpu, 4gb ram, 500gb WD Black HDD (a faster model than most spindles drives - though slower than SSD). Generally quite adequate for my use of QGIS but can be improved. I can use several Gb of data as shapefiles or Postgis tables, processing with R, reprojecting on the fly, surface modelling, etc, & I find it satisfactory - not blindingly fast, but not really waiting too long for anything. For a fastish version, I add 4gb memory (8Gb total), get a modular HDD enclosure to fit the removable optical drive bay & add an SSD for boot & swap, install Linux & run Postgis on the spindle drive. Works out at <$300US for a pretty quick system for most things. Also has pretty good battery life for the performance. One point to note - be careful on your cpu choice. I7 does not mean faster than I5, but does generally mean more cores. Clock speed is also misleading, an I5 2.67 cpu can be substantially slower than an I5 2.6Ghz (I have one of each in front of me right now - with same memory & disk). eg: from PassMark CPU Benchmarks - High Mid Range CPUs Intel Core i7-2640M @ 2.80GHz 3,914 Intel Core i7-4550U @ 1.50GHz 3,893 Intel Core i3-4110M @ 2.60GHz 3,873 Intel Core i3-2120 @ 3.30GHz 3,869 Intel Core i7-3537U @ 2.00GHz 3,857 Intel Core i5-5300U @ 2.30GHz 3,849 While these don't tell the whole story (mix of laptop/desktop versions), it is likely that you would often not see much difference between these cpus in terms of performance - but simplistically, the more QGIS takes advantages of multiple cores, the more a FAST I7 is likely to work better. I would not go below I5@2.5Ghz for QGIS. Hope this helps... vague as it is, but performance is not a simple question...

Hi, Don't save as a pdf - these do not generally work as georeferenced images & QGIS cannot create a geopdf. The easy way is without using the print composer, just save the project as an image (Project menu) - the default is a georeferenced png (png + world file). Avenza cannot read these, but QGIS can. Open the png image you just saved as a new raster layer in QGIS, & then save it as a Gtiff format image. This should create a geotiff of the map that you can read with Avenza.

Hi Stephen, What sort of database? While QGIS can talk to several popular spatially enabled databases directly (MySQL, PostGIS, SQL Server, Oracle, etc - sometimes with a bit of work) and to non-spatial databases with virtual data sources, it may be simpler in your case to export the data as CSV and open it as delimited text in QGIS. You will need to specify the field delimiter character, & the columns to use for X & Y coordinates, & the CRS (EPSG:4326 if lat/long decimal degrees), then QGIS will plot your data fine. If you still want to create a shapefile, use QGIS to save the layer as a shapefile.

Re: [Qgis-user] Organic heatmap outter contour, and making it look better
Generic Mapping Tools (http://gmt.soest.hawaii.edu) can do all you want, fully scripted: surface, triangulate, xyz2grd, greenspline can all generate a grid from scattered point data, depending just how you want it done gridhisteq can normalise it if requiredgrdimage will turn it into a postscript imageps2raster will turn it into a georeferenced png if you want to clip it to a contour, you can use psclip, or you can use a colour palette to set cells representing certain values to NA, & render them as transparent you can then provide it as a WMS layer with mapserver, qgis server or geoserver See sections 7.14-7.19 here:http://gmt.soest.hawaii.edu/gmt4/gmt/html/GMT_Docs.html GDAL may be adequate, but has a more limited set of gridding & cartographic tools, and GRASS can also do what you want.

Hi, I'm looking to build a LiveDVD/USB key with QGIS, OSM base layer and web services for New Zealand. Our road & topo data is very up to date in OSM, and we have numerous government (central, regional & local) agencies and others providing data via OGC services, so I'm hoping the system will have embedded OSM, and pre-loaded OGC servers to connect to, as well as some QGIS plugins specific to New Zealand.

Some years ago I built a laptop system demo'ed at several local schools which worked OK, with mapserver serving OSM via WMS direct from Postgis. NZ is small enough that the data could be rendered dynamically from the vector data in a reasonably interactive system. I can't reasonably use Postgis on a read only filesystem, and all the later guides assume that tiles will be used. Does anyone have any advice as to how I might best do this?

Re: [Qgis-user] Help reusing QGIS action
Cheers Bernhard, Yes, I can do that, but creating the action for each layer is the repetitive task I want to simplify. Instead of typing the the command line for the action, I could just select & apply. This is less of an issue for me as for the users less familiar with QGIS that I'm working with. Like I can create a symbology once, then save it & apply it to new layers, I'd prefer not to have to create the action for every layer - instead I could create it once then save & reuse as appropriate. As an institutional resource, I can create a set of QGIS styles (symbologies) that users can copy & apply to layers, without having t go through the complex operation of creating it themselves. It would be great to be able to do the same thing with actions - create a library of actions for institutional WFS services that users can re-use - which is where your suggestion of Python is a good one - being platform independent.

[Qgis-user] Free online QGIS training
For those wanting to make effective use of the free environmental and spatial data being made available by institutions such as LINZ, DOC, Landcare Research, NIWA, Statistics NZ, etc, (not to mention international resources such as OSM, NASA, WMO, ...) without buying into expensive commercial GIS software, there are several options, including the use of the world's most popular Open Source GIS application, QGIS. QGIS ibecame a core part of NIWA's Open Data policy, after it became obvious that providing open data, without tools tools enabling effective data reuse was a somewhat shortsighted approach.

Re: [Qgis-user] lat/log grid
Hi Kathleen, NIWA in New Zealand also needed this sort of capability, & paid Nyall Dawson (downunder QGIS developer) to implement improved lat/long grids & annotations to the QGIS map/print composer (he did a great job!) - but if you want the grid as a map layer, then you'll need to follow some of the links Anita suggested to create a set of lines forming the grid. You could also use use CAD tools plugin to edit parallel & orthogonal lines in a new layer, but beware that displaying lat/long lines in a projected map can be problematic - the straight line vs great circle issue. To create an image with a lat/long grid using the map composer (requires at least v2.6 of QGIS): create your map as usual & start a new print composer (file menu).1. add your map to the page (using tool on left side) 2. add a grid, choosing your spacing & labelling preferences - to create something like the attached image (using menu on right side) 3. Save as image (menu along top) Note that you can create multiple grids, which lets you have one grid with (say) 5 degree ticks/lines, then another with no ticks/lines but with labels at a 10 degree interval - so your map has every second line labelled. Hope this helps, if you need more detailed instructions, ask me off list...

Hi Michael, I'm (definately!) not a dev, but maybe can help I think the update all & update selected buttons pertain to the field calculator just to the left of the buttons, otherwise the editor is one row at a time. If you enter a string value in the column, then press enter, it will be saved. To use the field calculator, select the field you want to update (left hand pick list), then enter the formula defining the value...eg: for a simple string, for a 64 char text field called test, you finish up with the formula: test='HYT' (note that strings need to be quoted, numerics don't) then apply this to all or selected columns via the two buttons...

First of all, if any of the developers sees this - it's a wonderfull tool and a joy to use. Now, my question: I have a vector layer (ESRI shapefile) and I'm trying to fill some values. numerical values - no problem. I select some points (this is a point file), type the value I want, press "update all" and the column is filled with the value. But I tried the same with a text string (I created a new column and set it to type "string", made it 64 characters long to be safe), and it doesn't seem to work. after creation, the entire column has the value "null", but try as I might to enter a value and press "update all", this does nothing. If I do the same using a digit (and remember, this is a string attribute!), that DOES work for some reason. Any ideas what's going on? I've just tested it at home and the same problem exists, so it's not just my work PC. Oh, and another question, although I'm pretty sure the answer is no: I need to outline building outlines, which I currently do using other apps. But I'd love to switch to working with Qgis fulltime. Does QGIS have tools / plugins to help with drawing orthogonal shapes? I'm thinking about something that would let me draw one line freehand and then the rest of the lines would be constrained to be parallel or orthogonal to the first line. Alternatively something that would take a freehand-drawn polygon and straighten it. ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
Re: [Qgis-user] Creating oblique views of QGIS layers
Hi, I have not done this in QGIS, but have done it often with GMT. I've also used it to generate a page of maps showing a time series of survey results, each as a 3D perspective plot. A script draws a layer, then the next, applying a Z offset to each layer as it renders them, building the stack. You can use pstext to add text for each layer (which can be on the page - does not have to be in the map extent. At the end ps2raster can convert the postscript to bitmap which you cam add to your layout in the QGIS composer. Depending on how complex your layers are, the script can get a bit complicated... the nature of the beast. QGIS (or GDAL) can save your QGIS vector layers in GMT format, rasters can also be converted to a format GMT can render.

Re: [Qgis-user] Storing data to postgis from Qgis
David, Given your data is managed in Postgres, what you are doing seems (from my limited understanding) to contravene good data management practice. It is more a data management than (Q)GIS operation. Ideally you never replicate records in a database - this leads to data inconsistencies and update/maintenance problems. The approach generally used (apart from data warehousing cases) is to use views to create virtual tables, so your selects (which do not require QGIS to make - just to visualise) can be applied to create a view on your source table containing the desired records. You could wrap this functionality up in a script (language of your choice) to facilitate the creation & modification of such views, such as the addition of new records to an existing view - either by extending the where clause, or adding new record using "union". A stored QGIS project opening such views as layers will automatically pick up any changes made which impact on the view contents.

Hi David, I'm not sure why you are trying to do that from QGIS, given you can do it all from Postgis directly, especially given your data is already in a database, without the mapping/GUI overhead... nothing you have suggested as a means of selecting data subsets requires QGIS.

Re: [Qgis-user] How to store spatial information of various geometry types (point, line, polygon) in one place?
I agree - that approach to managing spatial data was last century's one. I recommend you use a spatially enabled database to manage spatial data . as many geometries/geographies as you want per feature. We have polygons with a point label location, linestrings with start finish timestamps as well as start, finish and mid points. >From a traditional GIS centric perspective the coords defining the spatial >representation of an entity has a special place - they are the entity, & the >other attributes just hang of it. A fundamentally flawed model according to >good data management practices. A good RDBMS stores a spatial representation value as just another attribute, you can have as many geometry, date/time, numeric or text fields describing your real world entity as you like... enablind spatial data to be corecvctly modelled & managed. Pretty much all GIS tools these days support connecting to an external spatial database as an alternative to an internal database or file based system. I prefer Postgis, but MySQL/MariaDB, or even the free versions of SQL Server & Oracle support the OGC SFS standard, which, amongst other things, defines an approach for storing simple spatial features in a RDBMS. If you want a cloud based approach - Amazon cloud supports Postgres, you can establish a database, install Postgis & insert your data, configuring the Postgres server to allow access from your systems as you require via IP afddress & user name.

Hi All, For work, we use a Google Sheets spreadsheet that is accessible to various people. The spreadsheet is mostly text attribute data with spatial information stored in WKT fields (points and polylines). When it comes time to make a map, I download a csv and import into QGIS. I realized that the csv import process will only allow one geometry type during the import and discard the others. This results in having to repeat the import process for each geometry type in the csv. Is there some better way to do this, ideally that would allow text and spatial data of various geometry types to be stored and read all at once? Is there a way to get around the seemingly archaic separation of vector layers based on geometry types? Is there a native QGIS format that can handle this and import from a spreadsheet? Or, ideally, is there some sort of magical connector between Google Sheets and QGIS, so a change online in Sheets would update the map in QGIS? cheers, kilolima -- View this message in context: http://osgeo-org.1560.x6.nabble.com/How-to-store-spatial-information-of-various-geometry-types-point-line-polygon-in-one-place-tp5159178.html Sent from the Quantum GIS - User mailing list archive at Nabble.com. ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
[Qgis-user] QGIS WMS/T problem
I have a colleage using QGIS with a problem accessing some local ESRI WMS/T services: * Dunedin City Council: http://apps.dunedin.govt.nz/arcgis/rest/services/Public/PhotoCache2013/MapServer/WMTS * Otago Regional Council: http://gisdata.orc.govt.nz/arcgis/rest/services/Imagery/OtagoRegionalAerials/MapServer/WMTS The Metadata tab on layer properties shows errors for right bounds (at all scales). And I've had no luck accessing ArcGIS rest services directly using qgis.utils.iface.addRasterLayer in the Python console. The layers work without problem in a web client using Openlayers. Can anyone shed any light on the problem? Other ESRI WMS/T services are working OK.

Re: [Qgis-user] print composer
If you can get by by saving the map canvas rather than exporting via the print composer - under project, choose save as image.
