[R-sig-Geo] Great Circle distances in Automap, Gstat

[Edzer Pebesma]

library(sp)
?is.projected
?CRS

Please note that to my knowledge (but I might be wrong) R does not have 
kriging functions with ready-to-go covariance functions that are valid 
on spherical coordinates. Of course you can write your own.
