Reference System (CRS) with identifier LonLat84_5773. Geodetic latitude, and altitude (in that order) as defined in Annex A of the KML specification by the GML Coordinate The encoding of every kml:Location and coordinate tuple uses geodetic longitude, KML relies on a single Coordinate Reference System, which is not referenced explicitly in KML files. KML can support not only the presentation of data on the globe, but also control the user's navigation in the sense of directing where to go and where to look.

KML files can pinpoint locations, add image overlays, and expose rich data through icons and captions.

KML is an XML grammar used to encode and transport representations of geographic data for display in an earth browser (3D) or online map (2D). was adopted as an international standard in 2008 by the Open Geospatial Consortium, Inc. Keyhole was acquired by Google in 2004 and the product became Google Earth. for use in a product called Keyhole Earth Viewer. The markup specification was originally developed by Keyhole, Inc.
