[Sgems-users] kriging with external drift

[sara s. <sar...@ya...>]

Dear all
I would like to use kriging with external drift on my data through gslib or (wingslib). As I know I have to define a regular rectangular grid for the estimation, in gslib programs. But I have my external data on a non-rectangular but regular grid (90m*90m)grid. How could I possibly define such a grid for estimation?
I appreciate any help so much.
Best regards
Sara
