EPSG code for...

[Dean C. Mikkelsen]

Hi Ken,
 
Thanks for the information.
 
The other problem I was looking at is that it may be a State Plane
Coordinate System as well. 
 
California is divided into many zones and the dataset being worked with
did not include some of the projection information.
 
Cheers,
Dean

Dean,
 
Make sure you have the Proj software installed, there's information
about it here:
 
http://www.maptools.org/maplab/index.phtml?page=maplab_windows.txt
 
and here:
 
http://www.remotesensing.org/proj/
 <http://proj.maptools.org/>  
If you haven't already, grab the windows binaries, unzip and place the
Proj folder on your C drive.  
 
C:/Proj
 
Cheers,
Ken Lord

I am using the latest version of ms4w, with Chameleon using MapServer
4.4.2

Any suggestions?
