This question already has an answer here:
I would like to know what kind of computation I could perform on a terrain database.
I'm making terrain for VBS2 from raw data (shp files and DTM Elevation files) and then I'd like to be able to check correlation between these two terrain. I want to check that VBS2 created terrain is ''enough'' correlated with the previous data.
I planned to check the shp files and DTM files of course.
But I was wondering if there is mean, median or coefficient that I could calculate on the terrain. Moreover, should I grid the terrain and analyze each square? Thanks
