Detailed Description

A Tile id, uniquely identifing a tile by its level and (unique for the given level) tile coordinates.

Note that this are libosmscout tiles, that evenly split the whole world into - for each level - equaly sized (regarding their latitude and longitude interval) rectangles.

Classic OSM tiles are calculated differently.
