Have a look at s.cellstat, http://pweb.jps.net/~egm2/grass/s.cellstats/s.cellstats.html , its a combination of s.univar and s.windavg with very acceptable performance. r.to.sites -a s.cellstat s.to.rast Should do everything you want. I'm not sure of the current status of s.cellstat. It was written by Eric Miller back in September. He was going to add it to the source tree, but I don't know if he has or what version.

Or did you mean something else? -- Glynn Clements <,glynn.clements@xxxxxxxxxx>, Have a nice day, I am creating interpolations from sites informations using both (IDW, spline) methods and I realized that color tables of resulting raster maps differ (IDW is more like blue, spline looks more like brown). Is there any way to change it? Thanks Jan Kohout --------------------------------------------------------------------- HoK Honza Kohout student Fakulty Informatiky MU clen 137.

I use GRASS version 5 and have tried using both r.in.gdal and r.in.tiff. The TIFF files were generated in Freehand 9.0 (and since it didn't work) then in Adobe Photo Deluxe - the error message indicated they were unsupported files. (I have tried 8-bit and 24-bit - neither worked.) I have had success in importing other TIFF files generated from scanned documents and in importing geoTIFF files. One other note - while the TIFF files were generated in Freehand/Adobe - the files were originally Autocad version9 files. Thanks Linda Source.
