MapTileTree Class
Beta
A quad tree consisting of MapTiles representing the map imagery draped onto the surface of the Earth.
A MapTileTree enables display of a globe or planar map with map imagery obtained from any number of sources, such as
Bing, OpenStreetMap, and GIS servers.
The specific imagery displayed is determined by a Viewport's MapImagerySettings and BackgroundMapSettings.
The map or globe may be smooth, or feature 3d geometry supplied by a TerrainProvider. The terrain displayed in a Viewport is determined by its TerrainSettings.
