Dear Rajni anyway if your aim is a quick spatial estimation there are some instruments that implement some specie of generic variogram by itself and return the interpolated data directly. Kriging made with Surfer is basically implemented with an automatic variogram fitting...so you can use Kriging not knowing neither what a variogram is. Obviously the results are questionable...the basis of geostatistics, that is the knowledge of spatial autocorrelation of data, come to miss...it depends on the targets. Regards Simone
