Package: GeoDist 0.1.0.8000

GeoDist: Constrained distance calculation and associated geotools

This package allows the calculation of distances that are constrained by frontiers, islands, mountains, ... These distances are then implemented in classical geotools like kriging with a modified version of geoR functions.
