For further information, refer to the Microsoft Bing Maps Tile System documentation.

Usage

quadkey_to_tileXY(quadkey)

Arguments

quadkey

A QuadKey as a single string.

Value

A list returning the tile X, tile Y coordinates and the zoom level.

Details

Converting latitude/longitude coordinates into a QuadKey and then back to latitude/longitude won't yield identical values, unless the initial latitude/longitude coordinates correspond to the upper-left QuadKey's pixel and tile XY coordinates at the same zoom level.

Understanding this distinction is crucial for the accurate use of these functions in coordinate conversions.
