predictive modeling

[The Einhorn Family]

Hello

I am to become the computer guru for a group using GRASS, 
to develop an predictive model for archaeolgical sites on Kirtland
AFB at Albuquerque, NM.

I would like to contact other groups working on similar projects.

Already know we want to use the watershed computations.

What kind of resolution would be required in a digital image to
"see" a midden heap?

Thanks,
