Convert pixel XY coordinatess into lat/long coordinates.

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).

Value

A list with the longitude and latitude.

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.

For a detailed explanation on how to use this and other similar quadkeyr functions, read the the vignette: https://fernandez-lab-wsu.github.io/quadkeyr/articles/quadkey_to_sf_conversion.html
