Dear list,
I am going to teach a coure on GIS and I would like to use GRASS. Some questions.
1.- Should I introduce the students to the newer version 6 or use to the stable 5.4
2.- Are there any teaching materials for the lab, tutorials, that could assist me on this task.
3.-How can I overcome thee concurrent access problem, creating and account for each user or is there another route.?
Thanks in advance

Consider using Markus' and Helena's Second Edition of "Open Source GIS: A
GRASS GIS Approach" as the textbook. See <http://www.springeronline.com/> for
details.

The GRASS book is very good but aimed at GRASS 5.4. Most raster and GIS
things are the same, but sites and vectors have changed. It is worth
having a look at.
The GRASS 4.2 Seeds Beginner's Tutorial (Leics) is nice, but somewhat
out of date.
3.-How can I overcome thee concurrent access problem, creating
and account for each user or is there another route.?
GRASS 6 allows concurrent use, just make a different mapset for each
user and keep the read-only but viewable-from-all-mapsets maps in the
PERMANENT mapset. Concurrent use of the same mapset is not allowed, and
users should not be encouraged to start switching mapsets mid-session if
there is a chance of collision. If each user is running from their own
account and the data is central, they should be able to view others
mapsets as read-only so not much danger there.
Would it be centrally installed binaries or run off of an application
server? If app server, you might have to do some (known) hacks to slow
down the 100% CPU use during mouse queries; it's an outstanding issue.
Dear list,
I am going to teach a coure on GIS and I would like to use GRASS.
Some questions.
1.- Should I introduce the students to the newer version 6 or use to

From my point of view I would highly suggest to use the stable version
GRASS 6.0 or even the shortly upcoming version 6.0.1.
You students should definitly have a look at the new vector features in
GRASS 6.
Furthermore nearly all raster-modules are ported to GRASS 6.
2.- Are there any teaching materials for the lab, tutorials, that
could assist me on this task.
GDF Hannover bR [1] offers trainig cources and tutorials [2] as well,
currently only in german language. A english translation is ready
translated and needs only some "polishing".
Again, as other posters already mentioned the book Neteler/Mitasova
[3]/[4] is excellent as a GRASS reference book.
3.-How can I overcome thee concurrent access problem, creating
and account for each user or is there another route.?
I am not quite sure what you mean. If you are talking about users on a
single system, it is good to have single users on one maschine.
If you are talking about a distributed data-basis (e.g. on a NFS-mount)
you should create seperate mapsets for seperate users.
