DSM generator with a building shp

[atoulou]

Hello,

I would like to generate a DSM with the preprocessor of UMEP on a part of the Lyon metropolis.
I have a DEM file (1m resolution), and a building vector file with a "HAUTEUR" column where the building heights are.
When I generate the DSM, not all the buildings are taken into account (although the building heights are available in the building vector file).

Why is this happening ?

Thanks in advance for your help,

Best regards

Hi,

Hmm, not sure. I could not replicate your error. Here's my result:
DSM.zip

Cheers,

Actually your file is good, but I ran the procedure again and I getthe same result (without all the buildings), did you do something different ? Or do you have any idea what can I check that might cause this error ?

Thanks again

Best regards

No, used same settings as you did. Strange that it adds only some buildings. Not sure what could cause this.
