I have a large DEM reprojecting from lon/lat to Lambert Conformal Conic and specified the lanczos_f method to minimize smoothing (the west edge of the DEM is at the coast).
I would like to learn how to minimize processing time when modules accept a higher-than-default amount of memory dedicated to them and the maps are very large.
The wiki page on parallel grass jobs, working with tiles section, looks like the way to go. Has anyone a more complete example of using g.region and WIND_OVERRIDE so I can see what I need to do with the 31 remaining large 10m DEMs that need to be reprojected? The ellipses leave me clueless about dividing a raster file with 8*10^7 cells. I'm looking forward to learning this, Rich _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/grass-user
