Re: [Qgis-user] question about GDAL module ( QGIS 3.4.14-1 and 3.10.1-A)
Thanks so much that worked! For neophytes like me- I had to add a custom environmental variable called PYTHONPATH and set that to the *.py modules location (searched my C drive to see the various locations, selected the one with the root paths in the installation being used). … Cinda Graubard GeoMax 303.440.4539 office 720.272.9812 mobile GIS for Mineral Exploration 2D and 3D Visualization, Integration, Analysis, Modeling Project and Data Management Data capture and conversion Databases Software Sales and Training -Original Message- From: Qgis-user On Behalf Of andreaerdna Sent: Sunday, December 15, 2019 2:53 AM To: qgis-user@lists.osgeo.org Subject: Re: [Qgis-user] question about GDAL module ( QGIS 3.4.14-1 and 3.10.1-A) The bug was also reported on the QGIS GitHub Issue tracker: https://github.com/qgis/QGIS/issues/33386 Waiting for a bugfix, You can tray to workaround the bug setting the PYTHONPATH environmental variable (in QGIS, Settings->Options->System->Environment) to the path of the folder in Settings->Options->System->which there is the gdal_polygonize.py file.

Re: [Qgis-user] question about GDAL module ( QGIS 3.4.14-1 and 3.10.1-A)
Hi Cinda, I cant help diagnose the issue, but I can give you an alternative method of using gdal_polygonize Im assuming you are using this under Windows. Using the OSGeo4W Shell, navigate to the folder containing the dataset and then use gdal_polygonize raster_in.tif -f "ESRI Shapefile" shapefile_out.shp You can alternatively use the full file path also instead of navigating to a specific folder. A full list of additional commands can be found here https://gdal.org/programs/gdal_polygonize.html It should be quicker anyway than trying to run it from within QGIS Regards, Richard -- Richard McDonnell MSc Geographic Information Systems, FME Certified Professional FME Certified Professional FRM Data Management -- Oifig na nOibreacha Poibl?
