Working with census WMS raster in QGIS
Geographic Information Systems Asked by Velester on March 7, 2021
I established a connection to the WMS service of the german census . Displayed correctly.
I’ve tried to extract values from the specific raster, e.g. population, to polygons like in the picture below.
I’ve tried all relevant SAGA VECTOR <-> Raster Tools as shown in the picture below.
All attempts conclude into an error where it says:
Grid statistics for polygons:could not initialize data object.
It implies that the tools cant evaluate the data in the raster.
How do I do this working with (german) census raster data?
I am using QGIS 3.10.4.
