Dear list members, I have started using geostats only this year and therefore I appologise that my questions are too basic for this discussion list... I am using Variowin 2.2 and GeoEAS 1.2.1 to analise my data, and an early version of Surfer to contour the distribution. However, I've encountered various problems: 1. When I use latitude and longitude in my DAT file, in what units is the variogram x-axis (h)? 2. Surfer doesnt understand the grid file created by GeoEAS KRIGE. How do I transfer my results to surfer (until now, I've used the estimated values from cross validation to have surfer generate a grid file)? 3. My variogram shows completely different behaviour from distance A to B, than for distance B to C. I've tried fitting various nested models, but I havent been able to come out with a good fit for the whole variogram. Is it possible to analise A-B data separately from B-C data?
