❷❸❹: Map tile numbers ( tiled web map scheme).

⓿: Version from resource manifest or altitude manifest using region.

Texture, Mesh, Transformation(, Animation) These five tile styles are used for Flyover: Type We can authenticate URLs and retrieve textured 3D models from given coordinates (latitude, longitude).

mesh decompression (huffman tables, edgebreaker variant etc.).map tiling and conversion from geo coordinates.Roughly, these parts have been figured out: Similar work is done for Google Earth here. Reverse-engineering Flyover (3D satellite mode) from Apple Maps.
