[mapserver-users] GRID - how to display labels not in degrees

[Alexandre Dube]

Hey Jeff,

   Yes, it worked without setting any interval, but that made me realize 
my mistake.  The interval values are in degrees when using 4326, so 
switching to 900913 they must be in meters.  Setting them to more proper 
values, such as 1000000 instead of 2 did the trick.  It works fine.

Thanks,

Alexandre
