[GRASSLIST:1144] Re: Grass and mapserver question

[Jorge del Pozo]

Hello.

First you have to convert the vector map into a shape file:

#vector layer in SHAPE:
#v.out.shape map=soils type=area pref=soils cats=string
...
 DATA /path_to_htmldocs/spearfish/soils
...
DATA /path_to_htmldocs/spearfish/soils
...

or, if you want to display a raster map:
#GRASS raster map directly from location (8bit only):
LAYER
  STATUS ON
  DATA "/path_to_grassdata/spearfish/PERMANENT/cellhd/soils"
END

And also be carefully with the file's permisions.

Sorry for my poor english.
