Hallo,
I'm using extract roof tool from local government 3D basemaps. During task segment roof, the option for building footprints turn error (have red cross) after I added the elevation surface (DSM).
The error:
ValueError could not convert string to float: '0,200000'
I changed several times the building polygon with others but it didn't work.
I wonder what's the cause is. Could you please help?
