What are the best methods for interacting with GRASS via a web
interface?
GRASSlinks (there are several flavours):
http://pnwpest.org/glinks/index.html
(the Spearfish dataset may be of interest [Mount Rushmore, USA])
http://www.agcrc.csiro.au/4dgm/grasslinks/
http://www.regis.berkeley.edu/grasslinks/
http://www.regis.berkeley.edu/glinks/about_gl.html
UMN MapSever:
http://grass.itc.it/start.html
(click on "Start" demos)
I think the difference is GRASSlinks is more for dynamic GIS queries and
MapServer is more for queries of static maps (eg mapquest.com)..
There's a Java frontend out there somewhere as well, maybe that is
useful.
