[Mapserver-users] gdal reading grass-database

[Jan Hartmann]

I don't know what others are doing with GRASS/MapServer, but I use GRASS 
as a means to quickly generate derived maps (reclassified, clumped, 
contoured etc). Thanks to the GRASSLIB interface in GDAL I can visualize 
these immediately in my browser, much faster than with the standard 
GRASS viewing tools. Moreover, I can combine them with any other 
MapServer layer. It's really a sort of Rapid Development Tool for 
getting my rasters right.

And yes, GRASS is an excellent modelling tool, certainly in combination 
with PostgreSQL/PostGis and R, and MapServer can be an ideal frontend 
for all this. And even in production environments, meant for the whole 
WWW, the combination can be useful for rapid prototyping of visual 
results. Perhaps even direct access to GRASS layers for WWW users via 
MapServer would be viable; I don't have experience with that, but there 
are certainly professional environments where such a setup could be 
worthwile.
