Normal score transform of spatial data
List:
I have 2 related questions:
(1) first I have x-y-z data, where x & y are the geographic locations of
point values, z. I need to perform a normal score transform on the
z-values and maintain their geographic location. So, how do I go from
columns x-y-z to x-y-z-t (or x-y-t), where the t-values are the normal
score transforms of the z-values? Can I use qnorm(ppoints(data)) to do

Covariace or variogram surface
Hi
I'm interested in doing a anisotropy analysis of some spatial data and I
want to do a contour plot of a covariance or variogram surface to
visualize the directions of maximal and minimal anisotropy.
I know how to do a contour plot :-) but how can I obtain the variogram
surface having a geoeas format dataset (X, Y, Z) ?
Thanks
EJ
