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

[Mark Volz]

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
