Francisco,

A GRID keyword has been added to LAYER in Mapserver 3.7 that provides
the functionality you're looking for.  Here's an example:
=20
LAYER
  NAME "GRID"
  PROJECTION=20
   "proj=3Dlatlong"
   "ellps=3DWGS84"
   "datum=3DWGS84"
  END
  TYPE LINE
  STATUS DEFAULT
  CLASS
 COLOR 0 255 128
   LABEL
  TYPE BITMAP
  SIZE MEDIUM
  COLOR 255 128 89
   END
  END
  GRID
 MININTERVAL 0.10
 MAXINTERVAL 0.10
# INTERVALCOUNT 10
# MINARCS   16
# MAXARCS     16
  LABELFORMAT "DDMMSS"=20
  END
END
=20
This will render a grid in Lat-Long with one tenth degree spacing and
degree minute second labels.  For variable spacing, remove the min, max
interval tags.
=20
To allow Mapserver to pick defaults for the grid, simply specify
=20
GRID
END
=20
in your layer.

Subject: [Mapserver-users] Displaying Lat-Long grids in the map image?

Hello everybody.
=20
I want to set up my maps to show the Lat-Long (UTM or whatever) grids. I
got the idea that there is no way to add them as a property of the map
file, am I right? In that case, does someone has a clever idea to do
this? I made a shapefile with the gridlines cathegorized to show
different densities of gridlines at different scale levels, but I guess
that there must be much more elegant alternatives.
=20
Thank you all.
