Short description of the KML standard
The OGC Keyhole Markup Language (KML) is an XML language focused on geographic visualization, including annotation of maps and images. Geographic visualization includes not only the presentation of graphical data on the globe, but also the control of the user's navigation in the sense of where to go and where to look. KML is complementary to GML in the sense that it represents the visual representations of geodata (which typically includes cartographic stylings) and not the geodata itself (as is represented using GML). KML data can be directly viewed in Google Earth, Cesium Virtual Globe, and most geoinformation systems.

Implementations / Products
The following selection of products was made by the SDDI team and includes those implementations which are (or likely will be) used in the SSD project and from which we know that they are compatible with the requirements of the Smart Sustainable Data Infrastructure. Please note that the list is not a complete list of available or suitable KML implementations. The Open Geospatial Consortium provides a catalog of implementations of their standards which can be found at http://www.opengeospatial.org/resource. Note that also the OGC list is not complete and not necessarily completely up-to-date.
