[Qgis-user] Watershed - Catchment area upstream of a point

There is a known issue with "upslope" in later versions of QGIS. The way to solve it is to insert a small edit into the bit of notepad script that runs upslope. Read here SAGA Upslope Area tool error: tool need graphical user interface · Issue #44514 · qgis/QGIS · GitHub

Hi Thayer, sorry, I’m very busy at the moment. It would be very kind, if you open the issue. Thanks. Dirk Von: Thayer Young [mailto:thaye...@yahoo.com] Gesendet: Dienstag, 8. November 2022 20:37 An: Pispers, Dirk ; Alessandro Pasotti Cc: qgis-user@lists.osgeo.org Betreff: Re: [Qgis-user] PostG

Re: [Qgis-user] Watershed - Catchment area upstream of a point

Hi, I have used SAGA for hydrological analyses following the instructions in Hans van der Kwast's excellent book on hydroloy in QGIS. It worked well in my Japanese environment, but I forgot about the details. Still, Hans van der Kwast also showed how to use GRASS for the same purpose. I trie

Re: [Qgis-user] Watershed - Catchment area upstream of a point

Hi Tony, Just wondering If QGIS is using SAGA to do the work, have you considered installing SAGA & using it directly? Brent Wood Principal Technician, Fisheries NIWA DDI: +64 (4) 3860529 From: Qgis-user on behalf of Tony Shepherd (FarmMaps NZ) via Qgis-

[Qgis-user] Watershed - Catchment area upstream of a point

Hi All I'm wanting to use a DEM/DTM to automatically map the watershed/catchment area upstream of a known point. After a bit of reading, this appears to be a not-so-simple task but suggestions are to use the "Upslope Area" algorithm. In my case, the program fails to finish running, and

Re: [Qgis-user] PostGIS raster layer filtered by attribute

Hi Dirk, I have not seen a bug report for this yet. Would you like me to issue one? I was able to reproduce that the provider for views of raster tables did work in 3.10 but stopped working by 3.14. -Thayer On Friday, November 4, 2022 at 08:06:48 AM EDT, Alessandro Pasotti wrote: On

Re: [Qgis-user] Problem display overlapping lines

Hi, It would be nice to have this QGIS.  My first reaction is to use line offset but the end result is not predictable. You may need to work with Python to do this.  You could also probably create a model. If you need to identify the overlapping segments, you can use my Fix Directional Netwo

Re: [Qgis-user] Parameter Inputs (False/True) for SAGA: 'Point statistics for polygon' module is not passed correctly in QGIS python console

Hello everyone   I am not sure how to close a request to you again.    Meanwhile I found the error in the code section myself. The names of the parameters are not e.g. 'AVG ' as specified in the QGIS module logfile, instead they are 'AVG             ' (note the long 13 space after the G) as spe

Re: [Qgis-user] Opening a layout in "Zoom full" view

Hi, Just tested on 3.26.3 on a brand new install (Windows 11 and all).  I confirm that this is a problem.  I would do a bug report. This should not be an option. Layout opens at 5.7% even when saved at 100%. Nicolas Le 2022-11-02 à 4:42 p.m., Tony Shepherd (FarmMaps NZ) a écrit : Hi Nicola

Re: [Qgis-user] Exporting, processing and re-importing

Hi Magnus, This is the correct place for asking your questions. If you have a unique identifier you can join your altered Excel file to your original geometry file. From the Layer Properties of the layer with geometry choose "Joins" and click the green plus sign in the bottom left. Then choose
