KML

Keyhole Markup Language (KML) is an XML-based format that describes geographic entities. Developed and popularized for use with Google Earth, the KML specification is now maintained by the Open Geospatial Consortium (OGC). KML can be used to draw featuresA feature is a single record, also known as a row, that represents a real-world entity. It typically contains a geometry (point, multipoint, polyline, or polygon) and attributes but it can also contain just attributes.Learn more such as pointsA point is a type of geometry containing a single set of x,y coordinates and a spatial reference.Learn more, linesA polyline is a type of geometry containing ordered point coordinates and a spatial reference.Learn more, and polygonsA polygon is a type of geometry containing an array of rings and a spatial reference. Each ring contains an array of point coordinates, where the first and last point are the same.Learn more on maps or even designate text, images, and media that appear when the user clicks a feature. Developers can use KML files in the .kml or .kmz formats as the source for layers in ArcGIS applications. While KML was initially created to view features in three-dimensional Earth browsers, it is now supported in several two-dimensional web browser clients, such as Map ViewerMap Viewer is a browser-based mapping tool that can view, create, and save web maps. It can also perform mapping, visualization, and spatial analysis operations.Learn more, with certain limitations.
