KML is a file format used to display geographic data in a mapping application, such as 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).
The KML file specifies a set of features like place marks, images, polygons, 3D models, textual descriptions, etc. for display in Here Maps, Google Earth, Maps and Mobile, or any other geospatial software implementing the KML encoding. Each place always has a longitude and a latitude. Other data can make the view more specific, such as tilt, heading, altitude, which together define a “camera view” along with a timestamp or timespan. KML shares some of the same structural grammar as GML. Some KML information cannot be viewed in Google Maps or Mobile.
