Roger, Thanks for the help! I can try this tomorrow. What do the data look like? Do you have temperature and elevation at the observation points and elevation over the grid? < This is exactly what I have; but I have a question: the elevation values I have associated with the point locat

List: I can not seem to work out the syntax for using R/gstat within a GRASS 6.1 session to do universal kriging. I have a DEM (elevation data on a grid) and point data for temperature; theoretically, the temperatures should relate to elevation. So, I am trying to spatially interpolate the tem
