[ka-Map-users] blank map, lat/long/extent/scale problems?

[Paul Spencer]

Ryan,

you have UNITS METERS but have decimal degrees for extents.  This is  
definitely going to screw up mapscript.  This likely happened because  
the gmap map file has an LCC projection whose units really are meters  
and you seem to have copied that (including the cvs ID tag :)).  If  
your data projection is in decimal degrees then you should change  
your units to DD in the map file.

Cheers

Paul
