1. Having been a Grass user (and installer), I convinced a collegue to try
a few things. Unfortunately, though he can access GRASS4.1, he is unable
to access my database. After the initial specification of the location and
mapset, GRASS responds with a message saying "Sorry, no access to <<PERMANENT>>."
Afterwords, it lists the Mapsets in the location and says
"note: you do not have access to any of these mapsets"I have made sure that everyone has read access to the files in the mapset
(and in fact changed the protection so that everyone had write access), with no
change in the situations.I am obviously missing something simple. Does anyone have any suggestions?
Your colleague must have his own mapset, which he will create by giving a new
mapset name in the GRASS start-up window (be sure that the LOCATION directory
has appropriate write and execute permissions for him). Then, he can use the
g.mapsets command to designate which mapsets he can *read* data from. Only the
owner of a mapset can write to it, regardless of perissions (at least, using
standard GRASS commands!).
