[mapserver-users] meters to lat/lon

[Zhang, William]

Hi, I have not much knowledge about projection. Hope somebody can help me on
this question. I am using lcc projection to project tiger shape files. After
projection, the map extents were converted from Lat/Lon to meters. How to
calculate the map extents back to lat/lon unit? Because at client-side we
have some data with lat/lon and we like to plot these data on the projected
map.
	......
	UNITS METERS  
  	PROJECTION
    		"proj=lcc" 
    		"ellps=GRS80" 
    		"lat_0=33n" 
    		"lat_1=45n" 
    		"lon_0=96w"      
  	END
	......

Thanks for the help.
