Same to me.
Thanks to open source it's never too late.
If you guy's really stand up and show a need for such a plugin, I'll
think about it too.

Re: [Qgis-user] Multi users environment: From geopackage to a database?

2020-05-06 Thread Stefan Keller
Hi,

This should be IMHO an issue of highest priority for QGIS.

Jésahel  wrote
> I've created a script to deactivate wal on samba shares, because samba is the

That's interesting. Are you sure it's Samba?
SQLite FAQ [2] confirms that NFS has problems.
Did not find issues on Samba, but file locking with fcntl is mentioned here [3].

Goal should IMHO be that 1. No crash, 2. read-only multi-user access
should be possible and 3. writing users must be warned if QGIS isn't
able to exclusively open the file.
And Jésahel  script suggests, that at least point 1 and 2 are possible.

Hi

I think this could be a misleading error.
Try to reduce in the Heatmap dialog the "Output raster size" from
"99" (default) to something smaller like '1'.

I do have a final enhancement :-).

After writing e.g. "bakery or supermarket in Uster" into the
Overpass-Turbo wizard, one generates the query.
Then the query can be enhanced by replacing node/way/lines to "nwr"
and "out body; >; out skel qt;" from the output section at the end to
"out center;".
The first is an abbreviation and the second generates nodes from areas.

This is the result I'd like to propose:

[out:json][timeout:25];
{{geocodeArea:Uster}}->.searchArea;
(
  nwr["shop"="bakery"](area.searchArea);
  nwr["shop"="supermarket"](area.searchArea);
);
out center;

Yours, Stefan

[Qgis-user] QGIS to load spefific OpenStreetMap data

2019-05-14 Thread Stefan Keller
Hi,

I'm preparing a talk about QGIS and OpenStreetMap for the annual
meeting of the local QGIS chapter.

=> Question: How do you (users) load specific OSM data into QGIS, like
for example all bakeries of Zurich? (ways/polygons as centroids?)

Background: QGIS 2 had a built in downloader which is gone in QGIS 3.
This instruction is 4y old [1], and this wiki page seems to be
outdated too [2].

I know, that QGIS can read OpenStreetMap XML (.osm) and .PBF files as
vector layer. And I know about these two plugins: OSMDownloader [3]
and QuickOSM [4].

* OSMDownloader requests a bbox from the user, then downloads the
whole area through the OSM API using the OGR OSM driver.
* QuickOSM generates queries in outdated Overpass XML, but accepts
also the newer Overpass QL language, like for example the following:

[out:xml];
area[name="Uster"];
(
  nwr[shop~"supermarket|bakery"](area);
);
out body;
>;
out skel qt;

Can't you delete such attributes with same (lower case) name - and
their contents - before making the layer permanent / exporting it?

[Qgis-user] Processing tool GDAL Grid (Nearest Neighbor) with unreachable additional options in GUI

2019-04-25 Thread Stefan Keller
Hi,

I'm using QGIS 3.6.1-noosa and I want to use the processing tool "GDAL
Grid (Nearest Neighbor)" GUI in order to call gdal_grid as follows:

gdal_grid -a nearest:radius1=1:radius2=1:nodata=-99 \
-txe 50 350 -tye 650 450 -outsize 3 2 -zfield z \
"grid in.gpkg" "grid out.tif"

There are two issues here:

1. The options "-txe 50 350 -tye 650 450 -outsize 3 2" are unreachable
in GUI. Using GUI section "Additional generation options [optional]"
generates wrong options "-co txe -co 50 -co 350 -co tye -co 650 -co
450 -co outsize -co 3 -co 2".

2. In and out file names are not enclosed by parantheses,

What can I do (except calling gdal_grid from command line, which is OK
for myself but not for end users)?

Re: [Qgis-user] Convert arc .lyr to qgis

The only thing I know of which work is getting access to ArcGIS and

P.S. Hint with tongue-in-cheek (but with a grain of truth): Ask the
public administraion about GeoPackage with QGIS styling - that would
be more up-to-date :-)

Re: [Qgis-user] WMS/GeoWebCache image quality in QGIS

2017-11-22 Thread Stefan Keller
This reminds me to issues with OpenLayers plugin.
Which lookup table are you using? Are you sure you set the scale
_exactly_ so it fit's the zoom level?
QuickMapServices plugin has such a functionality ("set proper scale"),
did you check this too?

--Stefan

P.S. If issues with raster base maps persist, consider vector tiles ;-)

[Qgis-user] Expression Functions: Where are they used in QGIS Desktop? Which ones won't work "outside"?

2017-05-07 Thread Stefan Keller
Hi,

Tomorrow I'll be giving a Workshop about "Easy Programming QGIS with
Python for custom Expression Functions (EFns)" [1].

Question 1: Below you'll find an initial list I compiled where EFns
are used in QGIS Desktop. => Did I miss an occurrence?

Question 2: I tried to make a categorization for several reasons. One
reason for this is to realize that a EFn may not work outside QGIS
Desktop. Style-related EFns for example won't work currently in
qgis2web or QGISCloud. => Any comments?

:Stefan

[1] https://2017.geopython.net/#schedule

List where EFns are used in QGIS (probably incomplete):

"Server-side" / data-related:
* "Select features using an expression" (Layer property).
* "Filtering features" while loading from source. Switch to the form
view in the attribute table (button on bottom right corner) > click on
'Show All Features' (bottom left) and select 'Advanced Filter
(Expression)'.
* "Layer > Properties > Tab Fields" in Button "Text Edit" in Default-
and in Constraints-Field.
* "Layer > Properties > Tab Style" in "Label with".
* "Field Calculator" to defining new or virtual fields (Layer property).
* "Conditional formatting" in the attribute table (Create a new rule
and set the condition to the output of a custom EFn).
Analysis-related:
* "Statistical Summary" Panel (Layer property).
* "Atlas Generation" in the Print Composer. Project > Print Composer >

Re: [Qgis-user] Drive time analysis tool

2017-05-03 Thread Stefan Keller
There's the QGIS Roadgraph Plugin - a Core Plugin - but it's rather
limited, only Point-to-Point (A-to-B) routing.

For most analyses like isochrones etc. you'd need distance matrices,
where I only know Python scripts: See e.g. Anita Graser's
https://github.com/anitagraser/QGIS-Processing-tools/search?q=route

I think it's time to think about a "Network Analysis" plugin similar
to ArcGIS' Network Analyst :-)

I sometimes see this effect when ArcGIS users save Shapefiles (or
other stuff) in a .gdb directory.
So your data could be in a format different from ESRI Geodatabase?

But I can't help without further info and specific data.

Re: [Qgis-user] R: Openstreetmap offline with QGIS

2016-08-07 Thread Stefan Keller
Hi all,

Be aware that OSM2VectorTiles offers Vector Tiles - not the usual raster tiles.
MBTiles is an SQLite file format which can store both.
There exists no Vector Tiles reader yet for QGIS (except my
experimental project which is not working yet [1]).

But there exist solutions for local raster tiles from OSM.
Bernd explained one of them using QGIS and QuickMapServices and QTiles plugins.
You could also use GDAL at the command line to produce the MBTiles.

Another approach for a base map would be to get an (optimized) GeoTIFF
format, then load this into QGIS.

Re: [Qgis-user] Adding OpenSeaMap to QuickMapServices

2016-04-13 Thread Stefan Keller
Hi Anita

I tried to configure this OpenSeaMap map and it's being added.
See my configuration below [2].
When zooming in/out the plugin reports that tiles are loaded, but I
even don't get confetti; only an empty screen.
On the other hand I could succesfully load some of the TMS services I
compiled here [1].
So I guess, it's a problem with the OpenSeaMap TMS server - not the plugin.

Yours, Stefan

Re: [Qgis-user] Editing shapefile attributes in QGIS

2014-12-21 Thread Stefan Keller
I would strongly recommend to avoid Shapefiles since it's a format
from grandfathers days (e.g. with obscure short field name length).
You can save the Shapefile in Spatialite (and soon as GeoPackage)
format which is based on a single SQLite file.
Then, you can edit this (besides inside QGIS DB Manager) also e.g.
with admin tools like "DB Browser for SQLite" [1].

Yours, S.

No it doesn'nt need to be gauss resampling method.
We found that GeoTIFF with overview index performs fastest.

Re: [Qgis-user] QuickOSM, a QGIS plugin to query Overpass

2014-10-16 Thread Stefan Keller
Salut Etienne

Cool plugin!

There are other Overpass instances around, like http://overpass.osm.ch/api .
So it would be useful to configure them.
I've seen that you have the information put statically into the code at
\.qgis2\python\plugins\QuickOSM\ui\main_window.py

self.comboBox_default_OAPI.setItemText(0,
_translate("ui_main_window", "http://www.overpass-api.de/api/";, None))
self.comboBox_default_OAPI.setItemText(1,
_translate("ui_main_window", "http://overpass.osm.rambler.ru/cgi/";,
None))
self.comboBox_default_OAPI.setItemText(2,
_translate("ui_main_window", "http://api.openstreetmap.fr/oapi/";,
None))

It would be nice to have this in the Parameters section - or at least
as a parameter in osmconf.ini
(\.qgis2\python\plugins\QuickOSM\osmconf.ini)

[Qgis-user] Generating GeoTIFF overview ("gdaladdo -r gauss ...") takes days for 2GB file...

2014-10-12 Thread Stefan Keller
Hi,

I have a GeoTIFF file of 2GB size. Now, this question is about
gdaladdo and how to optimize loading time of such a large raster file.

According to my observations QGIS has fastest loading times when it's
a single GeoTIFF file with overview images.

Q.1: Does anybody have tipps for even faster solutions loading raster
files into in QGIS (prepared by OGR or other preprocessors)?

The command "gdaladdo -r gauss C:\SG.tif  2 4 8 16 32 64 128 256"
takes actually about 7 days on a Lenovo notebook.

Q2.: Any hint's on how to accelerate this (or to other tools
generating overviews/pyramids)?

Yours, S.

Re: [Qgis-user] R: QGIS 2.4 Basic Tutorial

2014-07-26 Thread Stefan Keller
Hi Michael

After the OSGeo Vienna Code Sprint I've launched a (german) page here:
http://giswiki.hsr.ch/QGIS-Materialien

My idea was to wait until there's a learning material space at qgis.org.
=> Maybe it's time now to launch such a subsite (in english and/or for
each language)?
(perhaps somebody of the qgis.org admins can help?)

Let me also mention, that we're using also a "QGIS Portable for
Education" (reduced "power user functionality") and members of my
Geometa Lab) launched at the code sprint 1. QGIS plugin "Quiz" and 2.
an "All-in-one Project". The latter is similar to  ArcGIS Layer and
ArcGIS Map Packages and allows to package and exchange whole set of
project, configuration, symbology, data and instructional files:

Re: [Qgis-user] QGIS 2 and interlis format

2013-10-21 Thread Stefan Keller
Yes, it's probably not compiled by default under Linux because of it's
dependency to a Java runtime.
In addition, the Interlis 2 driver is incomplete.
There is a project underway which delivers a new Interlis 1 and 2 driver
end of this year (without Java dependency).

Re: [Qgis-user] [Qgis-developer] About a 'directed' LINESTRING (e.g. for oneway streets)?

2013-09-01 Thread Stefan Keller
Hi Alexandre

Thanks for the quick answer and the hint to the plugin LineSwitch (from
Underdark?).
Besides that the plugin page is'nt online currently for me - I'd like to
emphasize that my main question is about the reliability through all
processing steps to maintain the direction.
I actually want to hear if anybody had issues when importing/exporting
directed lines with OGR or analysing them with fTools or Sextante.

Yours, Stefan

2013-09-01 Thread Stefan Keller
I'm designing a spatial database and like to introduce a LINESTRING where
the direction is important, e.g. to describe a oneway street or a water
pipe. I indicate this by another attribute, e.g. "direction: BOOLEAN", or
"direction: ENUM(both, as_is, reverse)

A "directed line" means that the order of the coordinates of a linestring
value is important - like in a directed graph - and needs to remain the
same whatever happens to it e.g. when importing, storing, retrieving,
analysing or rendering...

Does anybody have had any issues to manage "directed lines" in QGIS (OGR,

Hi Polyglot

Just to be sure I'd like to point to the existing OSM plugin for QGIS
[1], which deserves an evaluation and probably needs some care.

Then, although I'm an active PostGIS (Postgres) supporter, I would
recommend Spatialite (SQLite) instead, given you use case.
It's more lightweight because it does not need a server installation
and you probably only use it as a temporary store.

Yours, Stefan

We tried it with QGIS 1.8 (from OSGeo4W) but did not succeed yet (e.g.
no 'Pinch' gesture).
Now I think I know why it di'nt work because we used stable and not dev version.

Re: [Qgis-user] "Normal" mdb support possible for "normal" people?

2012-09-24 Thread Stefan Keller
Maybe I think about and extend my online GeoConverter with SQlite and
Personal or File Geodatabases some time...
But that's not suited to huge file sizes.
Do you think that could still help?

Yours, S.

Re: [Qgis-user] QGIS presence at the AGIT conference in Salzburg

2012-07-13 Thread Stefan Keller
Hi all

Thanks for the report, Andreas. Here's my two cents:

First of all I am happy that the workshop was accepted by the AGIT
team even though the deadline of the Call for Workshops was over.

So next year I hope we come up earlier with a workshop submission.
Actually I think that the next CfP will already weill be issued in
december this year! As you may have realized is that the gvSIG user
community even went a step further and organized a user meeting during
the conference.

Regarding the feedback to QGIS the most important issues already have
been said. Being someone who teaches at university level using QGIS I
only want to add following some specific issues which persistently
come up from new users:

First, some defaults configuration seem to be quite suboptimal and it
would be easy to assign the task of an optimized default setting to
some sort of "user experience" (UX) team.

Second, the testing of the windows version often seems to be neglected
or behind the "hardcore linux" committers.

Third, the whole handling of the CRS seems to be suboptimal: I'm
referring specifically to the layer CRS settings (accessed by the
context menu in the layer list to the left). In the dialog there,
there currently (1.7/1.8) is no clue which is the CRS which is
currently active (or "set").

Finally, there are more than one "modules", where there exists an
"old" and a "new" implementation of the same functionality, like the
labelling engine. At least for new users I would expect that the new
functionality should be activated (maintainers of legacy applications
should be experienced enough to "switch" and configure back since they
have to test new QGIS version anyway).

Yours, Stefan

Hi,

I think giving a workshop would be a good idea from the project point
of view but also for the attendees at AGIT.

I would propose to present something around "Programming
QGIS-Applications for Beginners with Python Plugins", perhaps enhanced
with a roundup of new features.

I'm involved elsewhere at the conference but I could contribute a use
case in environmental planning and a use case in emergency gis (see
http://www.gis.hsr.ch/wiki/GIS_im_Rettungsdienst ).

[Qgis-user] Kurse fuer Schweizer Raumplaner zur Norm Nutzungsplanung Bund, HSR Rapperswil, August 2011

2011-07-21 Thread Stefan Keller
An alle Schweizer Raumplanerinnen und Raumplaner

Im Laufe dieses Jahres wird das Datenmodell 'Nutzungsplanung' des
Bundes in Kraft gesetzt. Gemeinden und Kantone werden diese Norm in
ihren Gesetzen und Aufträgen an die Raumplanungsbüros berücksichtigen
müssen. Dadurch wird es unabdingbar, dass sich Raumplanungsbüros auf
die neue Arbeitsweise mit GIS und die modellbasierte Geodaten-Abgabe
einstellen.

Der Fachverband Schweizer Raumplanerinnen und Raumplaner (FSU) bietet
daher zwei Kurse zur "Nutzungsplanung mit minimalem Geodatenmodell" an
der HSR Rapperswil an:

* Kurs 1: für Büroinhaber und Projektleitende, Mi., 10. August 2011.
* Kurs 2: für Sachbearbeitende GIS, Do., 11. August 2011.
* Ort: HSR Hochschule für Technik Rapperswil
* Programm: http://www.hsr.ch/Kurs-2-fuer-GIS-Sachbearbeiten.7300.0.html

Anmeldung per E-mail an Frau Sabiote, esabiote(at)hsr.ch,

[Qgis-user] Geoname Finder Plugin?

Hi,

Mashups and web map applications in general typically offer a search
input geoname search.

This is a text input field where one can enter a geoname and get

What about such a "Geoname Finder Plugin" for QGIS?
