This KML network link displays a map overlay for Maps-For-Free Relief (http://www.maps-for-free.com/) in Google Earth. The overlay grid is updated automatically each time the view changes, depending on camera height and angle. Maptiles are cached intelligently and can be superimposed with the original satellite imagery by changing the opacity of the link. For more information on how it works, see the
main page.
To start, simply download the file
world-maps-maps-for-free-relief-layer-for-google-earth.kmz and open it in Google Earth. Alternatively, a kml link with 2 different World Maps layers can be downloaded here.
