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.
