I am trying to set up a grass users group on our workstation so that
multiple users can access GRASS........
It looks like rass developers did not consider multiple accounts
working on the same data. Grass expects users to own his/her mapset.
Solution we found acceptable is:
1) create data directory tree in users account,
e.g.
cd ~/GIS/data .. this is the GISDBASE (different for each user)
2) crate symbolic links to PERMANENT databases inside this GISDBASE
for example, if copy of real data for global is in /grass/data/global
cd to cd ~/GIS/data/global (in each users account)
ln -s /grass/data/global/PERMANENT $GISDBASE/PERMANENT
etc in every's user account
Here is a script which does it:
$ more set_grass_data
#!/bin/sh
# create users map spaces by linking to PERMANENT
for mp in spearfish global imagery
do
echo 'setting up ' $mp
cd $GISDBASE; mkdir $mp; ln -s $GRASS_HOME/data/$mp/PERMANENT $GISDBASE/$mp/PERMANENT
done
ln -s $GRASS_HOME/data/imagery/spearfish $GISDBASE/imagery/spearfish
$
hope this helps - no guearantees !! pom@llnl.gov Peter O
