Members

Name	Documentation	Type	Description	Optional
Globe	The globe on which the longitude/latitude is specified	String	A valid scene graph node with a RenderableGlobe	No
Altitude	The altitude in meters. If the ‘UseHeightmap’ property is ‘true’, this is an offset from the actual surface of the globe. If not, this is an offset from the reference ellipsoid. The default value is 0.0	Double	Value of type ‘Double’	Yes
Latitude	The latitude of the location on the globe’s surface. The value can range from -90 to 90, with negative values representing the southern hemisphere of the globe. The default value is 0.0	Double	Value of type ‘Double’	Yes
Longitude	The longitude of the location on the globe’s surface. The value can range from -180 to 180, with negative values representing the western hemisphere of the globe. The default value is 0.0	Double	Value of type ‘Double’	Yes
UseCamera	If this value is ‘true’, the lat and lon are updated to match the camera	Boolean	Value of type ‘Boolean’	Yes
UseCameraAltitude	If this value is ‘true’, the altitude is updated to match the camera	Boolean	Value of type ‘Boolean’	Yes
UseHeightmap	If this value is ‘true’, the altitude specified in ‘Altitude’ will be treated as an offset from the heightmap. Otherwise, it will be an offset from the globe’s reference ellipsoid. The default value is ‘false’	Boolean	Value of type ‘Boolean’	Yes

Type	The type of translation that is described in this element. The available types of translations depend on the configuration of the application and can be written to disk on application startup into the FactoryDocumentation	String	Must name a valid Translation type	No
