GRASS itself offers various interpolation methods: http://grasswiki.osgeo.org/wiki/Interpolation#Reinterpolation_of_.22sparse.22_.28scattered_points_or_lines.29_maps I used elevation as auxiliary variable for temperature interpolation in v.vol.rst, obtaining the 2D raster map result via "output cross-section raster map". See http://grass.osgeo.org/grass64/manuals/v.vol.rst.html Another option is to call some R functionality from GRASS, see http://grasswiki.osgeo.org/wiki/R_statistics Markus _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
