This class is used to create a global terrain object representing a certain fragment of Earth's surface on the basis of available GIS data (elevation and imagery). The global terrain is rendered using pre-generated tilesets which represent LODs for different data layers (heights, albedo, normals, and masks). Tilesets are managed via the TileSet class. Tileset data is stored in tileset files on the disk, these files are managed via the TileSetFile class
