[Qgis-user] Install Postgresql and Postgis
Ubuntu 20.04, QGIS 3.16.3. I'm having problems installing Postgres and Postgis, the most recent version of the manual I can find says: $ sudo apt install postgis $ sudo apt install postgresql-9.1-postgis This doesn't work any more, Postgis installs but Postgres doesn't, I think the relevant file is missing from the repository. I'm stuck here, can anyone help?

Re: [Qgis-user] QGIS and SAGA 7.3.0
Hi berndv,
I thought we might be getting somewhere with your last suggestion, I made
the changes you mentioned and the SAGA NextGen tools duly appeared. I then
tried to run the SAGA Simple filter on a one-metre DTM, but this failed with
the message 'Unknown option 'MODE''. This is a step forward of course, I'd
not managed QGIS/NexGen to recognise SAGA at all before this. Here's part of
the output from the log:

Re: [Qgis-user] QGIS and SAGA 7.3.0
The SAGA NexGen plugin is flagged as 'Experimental', which I think means 'it may not work for you' - this is fair enough. I see that SAGA 2.2.5 is still in the repository so I think I'll do away with Version 7.3.0 in the short term and fall back on the older version, calling it from the Processing Toolbox as I used to. Many thanks for the suggestions, I'm always amazed at how helpful people are.

Re: [Qgis-user] QGIS and SAGA 7.3.0
Thanks for this, berndv. In the 'provider.py' file for SAGA NextGen I have tried changing the required version to 7.3 but this doesn't make any difference. I think it's probable that the plugin really does need a valid 'SAGA folder' to be set - and it's this that's got me stumped at present. All suggestions welcome!

[Qgis-user] QGIS and SAGA 7.3.0
Ubuntu 20.04, QGIS 3.14.16, SAGA 7.3.0 In QGIS I lean quite heavily on SAGA algorithms, which worked fine until I upgraded to Ubuntu 20.04 (focal). This forced an upgrade of SAGA to Version 7.3.0. Trying to use this from the Processing Toolbox resulted in a warning and problems, so I installed the SAGA NextGen Provider, in the hope that this would fix them. It hasn't, but I'm far from sure that I've set the required 'SAGA folder' correctly. It would be helpful if someone could tell me what this should be, or how to find out what it should be. I think SAGA 7.3.0 is correctly installed, is starts correctly with 'saga_gui' from a command line.

Thus, it would appear that gdal2tiles was not installed as part of the QGIS installation. Should I report this as a bug? (I'm always nervous of reporting bugs without checking first).

[Qgis-user] WMS Problem in QGIS 3.10
I have problems with loading UK Environment Agency WMS layers. This has only arisen since I installed QGIS 3.10. I understand that when QGIS makes a WMS request it adds the current version to the User-Agent string, so in version QGIS 3.10.0 this results in "Mozilla/5.0 QGIS/3.10.0-A Coruña" and that it might be the "ñ" character that's causing the request to be rejected. For testing purposes here is a typical EA WMS request: https://environment.data.gov.uk/spatialdata/lidar-composite-digital-surface-model-dtm-1m/wms I've reported the problem to the EA, but I wonder if I should report it as a QGIS bug as well? All of the above assumes that it is the extended set character that is causing the problem and of course this might not be the case. -- Sent from: http://osgeo-org.1560.x6.nabble.com/QGIS-User-f4125267.html ___ Qgis-user mailing list Qgis-user@lists.osgeo.org List info: https://lists.osgeo.org/mailman/listinfo/qgis-user Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-user

Just a thought. A friend upgraded recently and some of his settings didn't carry over, it was a CRS problem.

[Qgis-user] QGIS Processing toolbox and Grass 7
64-bit Ubuntu 12.04.5, QGIS 2.5 (nightly) from the Ubuntugis repository. I'm having problems with Grass 7 tools when trying to run them from the Processing toolbox. Processing fails with the error message shown below. I have tried deleting /home/nick/.qgis2/processing, but the problem persists. Grass commands stopped working after I removed my old installation of Grass and replaced it with Grass70. Under 'Processing options' I have unticked Grass and ticked Grass 7, there do not appear to be any other (GUI) options available. Can anyone help? Regards, Nick.

Re: [Qgis-user] new user
Hi Gill, I might not understand your problem fully, but I think that as a newcomer to QGIS a reasonable approach would be to load your OS OpenData map images first and then load the contours. (I'd keep clear of the OpenData contour DXFs if I were you and go for the new contour data in shapefile format.) Once you have something that looks reasonable on the screen you could then export a high-res image from the Print Composer that could be loaded into Photoshop. >From what you have written I think your base mapping must be OS VectorMap District rasters. If I remember rightly these have a resolution of around 250 dpi so it probably wouldn't make much sense to export an image from the Print Composer at much greater than this.

Re: [Qgis-user] Polygon digitalization
Just checking Bert, but have you seen this? http://confound.me.uk/maps/ppv4.pdf This is the way I work, I find it quicker than tracing polygons and it also separates the job of digitising from the job of entering data (which I find convenient). The only other way I can think of would be to start off with a large polygon and slice it up into smaller ones using the split features tool. Not tested here and I don't think this method will let you cut holes in polygons.

Raster -> Conversion -> RGB to PCT will convert an RGB image to a one-band indexed (paletted) image. You should be able to polygonise this by going Raster -> Conversion -> Polygonize.

It's difficult to know what is happening here.

Re: [Qgis-user] QGIS for surfaces documentation (of Mural Painting)
If you know the dimensions of the painting then georeferencing the image should not present problems. For example, if the painting is 200 cm wide by 100 cm high you could georeference the image using a coordinate of 0,0 for its bottom left-hand corner and 200,100 for its top right-hand corner. In the georeferencer use 'Helmert' and 'Linear' and set a CRS of (say) EPSG:3395. The CRS is not really important in your case, but you have to specify something.

Thanks for the response Victor. I didn't think I needed SAGA to be installed
to run GRASS functions from the Sextante tool box. In fact I'm pretty sure
that until a few days ago GRASS functions did run from the tool box without
SAGA installed. Anyway, I've installed SAGA, enabled it in the Sextante tool
box and the GRASS functions still don't work. Which has left me puzzled.
I don't have anything in the log tagged "Grass console output". I've just
tried using grass.v.parallel which failed with the same message as before.
The only thing written to the log file was under "Algorithm":
sextante.runalg("grass:v.parallel","/home/nick/beenham/walk_maps/long.shp",20,20,0,2,1,False,False,"458542.246135,459826.641395,168788.919831,170532.062032",0,None)

Re: [Qgis-user] getting statistics from a raster layer
One other thing, you want to collect statistics for your clipped raster, so when you clip the raster make sure that you tick 'no data value' and enter a value of (say) -3. This will set the value of the pixels in your clipped raster that lie outside of your area of interest to 'null' and they will be ignored when calculating statistics (which is what you want). I think the correct statistics for your area of interest are as follows: STATISTICS_MINIMUM=20.97500038147 STATISTICS_MAXIMUM=22.629600524902 STATISTICS_MEAN=21.829234117232 STATISTICS_STDDEV=0.40600423541182 Nick. -- View this message in context: http://osgeo-org.1560.n6.nabble.com/getting-statistics-from-a-raster-layer-tp5002022p5002891.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

Antonio Silva wrote > Following the suggestions I got an error message: "Cannot compute bounding > box of cutline." when cutting the raster. Just checking, but the raster layer and the vector polygon layer do have the same CRS? You can't cut a raster with a vector unless both have the same native CRS. In other words, both layers must align properly on the QGIS screen with on-the-fly CRS transformation turned off.

Re: [Qgis-user] getting statistics from a raster layer
I think the first thing to do is clip the raster to your area of interest using the vector polygon. Raster -> Extraction -> Clipper. Select the polygon shapefile as the mask layer. To get the statistics load the clipped raster, right-click on it in the layers panel, select "Properties" and then click the "Metadata" tab. This will show the mean, min, max and SD, but not (unfortunately) the median.

The alternative might be to use Google Earth. Select the line drawing tool and in the box that pops up click the "Measurements" tab and then select your units of distance. Then click on your starting point and draw a short line. Then pick up the end of the line and move it. As you do this you will see that the reported line length changes. When you've finished adjusting the line click "OK", then save the line as a KML file and load it into QGIS. Horrible really.

It's quick and produces perfect polygons. It also separates the task of digitizing from that of entering attribute data, which I find convenient.

[Qgis-user] RE: Qgis-user Digest, Vol 75, Issue 17 - 2. Re: Help: GPS data not showing in correct position
For form's sake, I should start by renaming the CSV file to something that doesn't have spaces, et cetera, for example, 'GPS_Android_points_IKE.csv'. Next, swap the LONG and LAT column headers, these are the wrong way round. When loading the CSV file into QGIS set its CRS to EPSG:4326. Find EPSG:4326 by entering 4326 into the 'Filter' field. Then sent the project CRS to EPSG:27700 and enable on-the-fly. Find EPSG:27700 by entering 27700 into the 'Filter' field. Then load the raster image and set its CRS to EPSG:27700.

[Qgis-user] Problem with Python scripts
Using QGIS Lisboa RC1 under Ubuntu 11.10 amd64. I have continuing problems with the Python scripts gdal_merge.py, gdal_polygonize.py and gdal_sieve.py. Trying to run these either via the Raster menu or in a terminal produces a segfault. The gdal executables are fine and these are in the same directory as the scripts (/usr/bin). Reinstalling QGIS does not solve the problem and I am now at a total loss to know what to do, especially as it appears that this behavior is not reproducible elsewhere.
