pixelXY_to_latlong {quadkeyr} | R Documentation |
Convert pixel XY coordinatess into lat/long coordinates.
Description
Converts a pixel from pixel XY coordinates at a specified zoom level into latitude/longitude WGS-84 coordinates (in degrees). For further information, refer to the Microsoft Bing Maps Tile System documentation.
Usage
pixelXY_to_latlong(pixelX, pixelY, zoom)
Arguments
pixelX |
X coordinate of the point, in pixels. |
pixelY |
Y coordinates of the point, in pixels. |
zoom |
Zoom or level of detail, from 1 (lowest detail) to 23 (highest detail). |
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.
