[MS4W-Users] How to mention multiple projections in MapServer MAPFILE?

Shiva,

Mapserver can take data from multiple layers and project each layer.  However you need to specify the projection of your map, and the projection that your incoming layers use.  I do not think Mapserver will automatically read a .prj file. 

Here is how you can take data from three projections and make a final map in UTM 48:

MAP
	#make mapserver produce a final map in UTM 48
	PROJECTION 
		"init=epsg:26915"	
	END PROJECTION
	...
	LAYER
		#source data in UTM 47
		PROJECTION
			"init=epsg:26947"	
		END PROJECTION
		...
	END LAYER
	LAYER
		#source data in UTM 48
		PROJECTION
			"init=epsg:26948"	
		END PROJECTION
		...
	END LAYER
	LAYER
		#source data in UTM 49
		PROJECTION
			"init=epsg:26949"	
		END PROJECTION
		...
	END LAYER
END MAP
