I am currently undertaking my final year dissertation looking at the automatic filtering of a Digital Surface Model to a Digital Terrain Model. In order to try and validate my data I have collected some 'true' height data using GPS. I have managed to load this into ArcMap 10 so that the attribute table has the height value. I was therefore wondering if anybody knew of a way that I could compare the height value collected from the GPS to the value I have for my Digital Terrain Model to see if there is any difference.
