Testing a Kriging program...

Hello out there,

Well I have now got a "working" kriging program for GRASS.
I have put "working" in quotes because I'm not sure how to
evaluate whether its doing what it is supposed to be doing.

I have passed the visual stage, i.e. the maps look like what
I would expect in terms of pattern and the pattern is
similar to that which is produced from the inverse distance
algorithm. However, there must be a better method for gauging
whether it is working...???

Does anyone have a test data set that has been well used and
evaluated over time...one that they might use to test
something that they have written? Other suggestions?

cheers,

p.s. When I'm fairly confident that it is doing what it should
     be doing, anyone who wants a kriging routine for GRASS and
     the variogram analysis routines that I've written are more
     than welcome to them.
