Hi I have the following datasets for an area:
1. LIDAR DTM (Digital Terrain Model)
2. LIDAR DSM (Digital Surface Model)
3. Building footprints polygons
I would like to calculate the following:
1. Maximum height of each building footprint
(by subtracting DTM from DSM)
2. Area of each individual section of a footprint
(by overlay the DSM over the building footprint and delineate the individual boundaries of a footprint
based on the LIDAR classification)
Any ideas whether 1) and 2) can be done using ArcGIS or any of its extensions (3D or Spatial Analyst)?
Thanks
