Hello, If I generate a variogram with an outside program on the x-y plane, would this variogram be valid for ordinary kriging in gstat? I am giving gstat the x,y,z coordinates and I am trying to predict at the elevations of a digital elevation model. Thank you in advance for taking the time to answer such a basic question. Cheers, Cara [[alternative HTML version deleted]]

Hi, I would say there is no reason why not. But what do you mean by variogram, I think the variogram model. To use the model in R you only need to put it into the correct format. library(automap) data(meuse) coordinates(meuse) = ~x+y kr = autoKrige(meuse) class(kr$var_model) kr$var_model str(kr$var_model) cheers, Paul
