[GRASSLIST:6192] Re: Grass web tool

[Jan Hartmann]

Christian,

You can use Frank Warmerdam's GDAL library (www.remotesensing.org/gdal) 
to access GRASS datasets with MapServer. To do so you have to:

- compile GDAL with libgrass
- compile MapServer with this GDAL library

You can only display finished GRASS raster maps this way. If you want to 
operate on GRASS data via a web server, it should be possible to write 
PHP scripts to do so. The results of these operations can then be 
displayed by MapServer. I don't know if anyone has tried this out already.

Both the GDAL and MapServer sites offer precompiled binaries for 
Windows. I don't know if these include the GRASS link.

There are some recent postings on the mapserver-users list on using 
GRASS datasets with MapServer. See for example the thread from 
http://mapserver.gis.umn.edu/data2/wilma/mapserver-users/0304/msg00055.html
