[GRASS-user] r.cva

I did a fresh install of grass623. However, I forgot r.cva is an add on. I found the old threads when I did this install with Bejamin Ducke's help (AKA leading me by the nose because I'm clueless): http://lists.osgeo.org/pipermail/grass-dev/2006-June/024106.html

[GRASS-user] Connect additional dbf file based on layer 1 attribute column

Dear list, I am trying to import the European Vector Database (ESDB) version 2 to GRASS -- original data is ArcInfo shapefile. Maybe most of you already know about this freely downloadable database, but for those who don't: http://eusoils.jrc.ec.europa.eu/Library/ESDAC/Online_Data.cfm Well,

[GRASS-user] Fixing Collared DRGs

Hi folks- I'm new to GRASS, but am eager to learn a GIS that doesn't require me to use Windows. I can manage to do the basics with GRASS (although I'm having trouble with the python GUI, but that's another story). What I'm trying to do now is remove white collars from some GeoTiff topo maps I

[GRASS-user] v.in.ascii and overlapping areas

I am trying to use GRASS to do distribution maps of objects from an archaeological site. Some have exact findspots (points), others have general findspot areas (boxes). I have tried to export these using a standard v.in.ascii file. I export the four coordinates of the box boundary, and
