Feature Request: analog to sp::surfaceArea() #1587

Open hannahlowens opened 3 months ago

hannahlowens commented 3 months ago

As the subject line says, it would be fantastic to have a terra option for sp::surfaceArea()--that is, using an elevation raster to calculate surface area. I've been using cellArea/cos(slope), but it's not as satisfying.

The MultiscaleDTM::SurfaceArea function in can accomplish this if you're still looking for a solution.
