Very rookie user here asking a kind of odd question i am sure.
I am performing a viewshed, and have sucessfully gone from orthometric lines, to tin, to raster, made observation points, and finalized the viewshed sucessfully.
A twist is that we need to add vegetation to the existing surface. I have a polygon .shp file for this vegetation. And we were directed to simply have a vegetation height of 15 m for the canopy elevation.
How do i drape the vegetation, and add the 15 m as required. Meaning i was hoping to be able to use the "edit TIN" feature, with a field of 15 for each polygon and have that interpolate above the existing surface.
Is this even possible?
Thanks in advance to anyone who can help an idiot.
