What is KML?
KML is a file format used to display geographic data in an Earth browser such as Google Earth. 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).
Who uses KML
You can use KML to plan trips, share location data with friends, or record hikes you've been on.
Scientific data, such as natural resource maps, or geographic trends, are easily shared as a KML file.
