Keyhole Markup Language (KML) is an XML-based format for describing geographic entities. Developed and popularized for use with Google Earth, the KML specification is now maintained by the Open Geospatial Consortium (OGC). Developers can use a .kml or .kmz (compressed) file, or a URL pointing to a KML file as the source for a layer in an ArcGIS application.
