I have a raster image whose values are a digital elevation model of terrain.
I need to know the surface type (topographic characterization) of particular points along transects of this DEM.
How to find it?
(In my application I have two points: a transmitter end and receiver end. I find the highest point between the transmitter end and receiver end: see the figure below. I would like to know whether the highest point is smooth or is a knife edge; that is, to within the resolution of the image it appears to be non-differentiable.)Attachment 31719
