Minimun clearance between sloped surface and terrain

meliorly

Hi!

I would like to know a way to locate the point at which the minimum clearance occurs between a slopped surface and the terrain (eg ASTER) below it. In other words, i want to know the pint where de vertical difference between the surface and the terrain is minimal. In addition, I would like to know the coordinates of the specific point where that minimun clearance occurs, as well as its elevation.

Thanks in advance!
