Convert tile XY coordinates into a QuadKey.

Converts tile XY coordinates into a QuadKey at a specified zoom level. For further information, refer to the Microsoft Bing Maps Tile System documentation.

Usage

tileXY_to_quadkey(tileX, tileY, zoom)

Arguments

tileX

Tile X coordinate.

tileY

Tile Y coordinate.

zoom

Zoom or level of detail, from 1 (lowest detail) to 23 (highest detail).

Value

The QuadKey as a string.

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.
