The KML file format used by Google Earth, to allow developers to define custom layers which can be displayed by Google-Earth. KML, is an XML grammar and file format for modeling and storing geographic features such as points, lines, images, and polygons for display in Google Earth.
You can use KML specify icons and labels to identify locations on the planet surface, create different camera positions to define unique views, use image overlays which are attached to the ground or screen, define styles to specify feature appearance, write HTML descriptions of features—including hyperlinks and embedded images, use folders for hierarchical grouping of features, dynamically fetch and update KML files from remote or local network locations and deliver current view details from the client to the server in order to fetch KML data based on changes in the 3D viewer.
The kml file is processed by Google Earth in a similar way that HTML and XML files are processed by web browsers. Like HTML, KML has a tag-based structure with names and attributes used for specific display purposes. Thus, Google Earth acts as a browser of KML files.
