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

[Jan Hartmann]

John,

Am I right that labels have to be provided? When I try to draw the grid 
layer without a LABEL, MapServer crashes. With labels it runs OK, 
although it takes plenty of time, much more than when displaying a grid 
based on a shapefile layer.
