How to compute surface of raster or any point using ARCOBJECTS?

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.)[ATTACH=CONFIG]31719[/ATTACH]
