quadkey_to_latlong {quadkeyr} | R Documentation |
Convert a string of Quadkey numbers to lat/long coordinates
Description
This function converts Quadkeys to latitude/longitude WGS-84 coordinates (in degrees). For further information, refer to the Microsoft Bing Maps Tile System documentation.
Usage
quadkey_to_latlong(quadkey_data)
Arguments
quadkey_data |
A single QuadKey as a string or a vector with unique QuadKeys. |
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.
