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?
