Re: [GRASS-user] Import Shape Files

2020-07-01 Thread Martin Bittens
Hello Markus, first of all thank very much for your efforts. Unfortunately, the error message "Projection UTM (zone invalid) did appear anyhow although I replaced the *.prj file by that one you sent.  But now I figured out the following (after importing the shape file and making active): -

[GRASS-user] Monitor dislay time vs psmap display time

A 5m DEM displays very quickly on the monitor (using d.rast map=basin_5mtopo) but when that map is the raster in a psmap script it takes a very long time for grass to process the script (with the vector overlays). Why might this be? Regards, Rich ___
