[mapserver-users] Dem classification

[Dylan Beaudette]

Hi,

Here is a start:
http://grass.osgeo.org/wiki/Main_Page

the main idea:

# make a new mapset/location
# import dem:
r.in.gdal

# convert to classes
r.reclass

# fix colors:
r.colors

# export image:
r.out.tiff or d.out.file

Cheers,
Dylan
