<DIV><BR>hi,</DIV>
<DIV>i tried to import .hgt files using r.in.srtm but it didn´t work...r.in.srtm instead produces 3 files ... then i did run r.in.gdal to import the .bil file, but it didn´t recognize well the projection...i have another rasters i want to overlay but even if they (apparently) are in the same projection (lat/long wgs84) they don´t match...</DIV>
<DIV>can i change the projection of a raster without changing the location?</DIV>
<DIV>thanks</DIV>
<DIV>samuel</DIV>
