I have to calculate the DEM of countless small buildings. I have the footprints of the buildings as a polygon shape file. Is it possible to specify these footprints as boundaries for the "house-DOM"? Or do I first have to calculate a DOM for the whole area and then clip out the house areas again? Unfortunately I couldn't find anything in the readme file about this. For me, the areas outside the houses are not interesting, so that I don't want to calculate a DOM outside these house areas. I already tried it with -keep_class 6 -nodata -9999, but unfortunately it calculates the spaces in between anyway. Is there an hidden command?
Thanks a lot for your support.
