What is KML?

KML is a file format used to display geographic data in an Earth browser, such as Google Earth, Google Maps, and Google Maps for mobile. You can create KML files to pinpoint locations, add image overlays, and expose rich data in new ways. KML is an international standard maintained by the Open Geospatial Consortium, Inc. (OGC).

February 2009: Google Earth 5.0 is available, with support for elements in the Google extension namespace. These elements include new underwater altitude modes, time support for AbstractViews, and touring. Read the documentation for more information. To download Google Earth 5.0, visit earth.google.com.
