I'm waiting for a geobrowser capable of showing KML maps in different projections . The projections commonly used by geobrowsers are not the best choice for thematic world maps. Many cartographers dislike thematic maps rendered on virtual globes, and the Mercator projection is not suited for large area maps. Greenland looks like the same size of South America, while it is actually 8 times smaller. The coordinate system of KML is geographic (latitude/longitude) coordinates on the World Geodetic System of 1984 (WGS84) datum. Geobrowsers use different projection techniques to render a KML document.

Google Maps and Microsoft's Live Maps both use Mercator projection , which is a good choice for a map that can be panned and zoomed seamlessly .
