Hi Tim,
I have been in a similar situation, and modified some functions in geoR
in order to fit variograms, and perform kriging with non-Euclidean
distances. In particular, you can use likfit() and get
maximum-likelihood estimates for variogram models with non-Euclidean
distances.
You can get

Hello R-sig-Geo list,
I want to calculate maximum likelihood estimations for variogram
parameters (sill, range). My data locations span North America, thus I
believe that UTM coordinates (or any other projection) will distort
distances between sites too much for me to use Euclidian coordinates.
