thank you very much /Johannes -------- Original-Nachricht -------- Datum: Wed, 10 Aug 2011 12:43:42 +0200 Von: "Johannes Radinger" <jradin...@gmx.at> An: grass-user@lists.osgeo.org Betreff: Import global maps (Ascii, png or KLM) from riverthreat.net Hello, I've a question concerning the import of raster maps into grass: On http://www.riverthreat.net/data.html it is possible to get worldwide data on river threats and environmental pressures. The data are provided either as images (png), ascii files or Google-Earth KLM files with a resolution of 30 seconds (0.5 degrees). I'd like to import some of these maps into grass gis for further analysis. Thus some questions arise: *Which coordinate system do I have to select so that the data are displayed correctly? * What is the best data format for the import? I think maybe Ascii? These files have a header like following: ncols 720 nrows 360 xllcorner -180.000000 yllcorner -90 cellsize 0.500000 NODATA_value -9999.000000 Maybe you can help me with the import!
