I have LAS data. I have made a DEM from the LAS points. I have a Z-enabled polygon feature representing building footprints.
Somehow I need to incorporate the height of the buildings into my DEM so that I can do an analysis to see what portion of the ground behind the building is not visible from my observer point.
I have attached an image showing the LAS data as elevation along with the line work representing the buildings and the observer point.
