Convert tile XY coordinates into pixel XY coordinates

Converts tile XY coordinates into pixel XY coordinates of the upper-left pixel of the specified tile. For further information, refer to the Microsoft Bing Maps Tile System documentation.

Usage

tileXY_to_pixelXY(tileX, tileY)

Arguments

tileX

Tile X coordinate.

tileY

Tile Y coordinate.

Value

A list returning the pixel X and pixel Y coordinates.

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
