KML or Keyhole Markup Language is a file format used to render geographic data in an Earth browser such as Google Earth. An XML-based language for geographic visualization and annotation, KML was originally created for Google Earth. For more information, see https://developers.google.com/kml/documentation. KML files can be created to pinpoint locations, expose rich data in new ways and add image overlays.

The Reference shows which all tags are optional, and within a given element, tags must appear in the order shown in the Reference.
