Using Mapserver as a WMS server with Google Earth

There is a PHP script at this site for integrating WMS with Google
Earth:

Just wanted to pass along what else I needed to do to make it work
properly with Mapserver.  Google Earth does not support interlaced PNGs
so the following outputformat needs to be defined in the map file:

	OUTPUTFORMAT 
		NAME PNG24 
		DRIVER "GD/PNG"
		MIMETYPE "image/png" 
		EXTENSION PNG 
		IMAGEMODE RGBA
		TRANSPARENT ON 
		FORMATOPTION "INTERLACE=NO" 
	END 

WMS gets should include a FORMAT=image/png in the request.  Also make
sure that Google Earth is set to refresh after each draw and that should
do it.

Just a heads up,
Joe Miller
