pixelXY_to_tileXY {quadkeyr} | R Documentation |
Convert pixel XY coordinates into tile XY coordinates
Description
Converts pixel XY coordinates into tile XY coordinates of the tile containing the specified pixel. For further information, refer to the Microsoft Bing Maps Tile System documentation.
Usage
pixelXY_to_tileXY(pixelX, pixelY)
Arguments
pixelX |
Pixel X coordinate. |
pixelY |
Pixel Y coordinate. |
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.
