Hi all

I want to compare different methods for computing DTM's slopes and aspects
from unequally spaced data . Does anyone have any data for which elevation
slopes and aspects are known ? Failing that what about suitable test functions
from which these things could be calculated ?

Has anyone done or seen something like this already ?

thanks !
