I'm trying to determine the visibility of a property (polygon) from surrounding sites within the same county. Sounds simple, but here's the catch: it's a solar farm analysis project, and the county requires the subject site be 'invisible' or not visible from any other property in the county. That said, the property currently has a thick loblolly pine plantation along its edges (trees are approximately 20m in height). So I've run a bare earth viewshed analysis (no problem with that one) BUT am trying to figure out how to run a separate analysis that incorporates/considers the height of the pines as an obscuring factor. Any chance you could help with this?
I don't have a DSM to work with, just a DEM.
