The quadkeyr R package presents a comprehensive toolkit
tailored for generating raster images from Quadkey-Identified data
within Microsoft’s
Bing Maps Tile System. Designed to integrate Quadkey-Identified data
into R workflows, this package facilitates the creation of QuadKey grids
and raster images and introduces specialized functions for the
processing of Meta Mobility
data, previously referred to as Facebook mobility data.
Tile maps divide the Earth’s surface into a grid of tiles, with each tile corresponding to a specific geographic area at various zoom levels.
QuadKeys represent a location on a map by encoding its hierarchical spatial position as a sequence of characters. They provide an efficient method to address and retrieve specific map tiles, facilitating rapid display within mapping applications.
The QuadKey of any tile starts with the QuadKey of its parent tile (the containing tile at the previous level). Image extracted from Microsoft’s Bing Maps Tile System webpage.
The goal of quadkeyr is to:
quadkeyr provides functions to convert a QuadKey to a
sf POINT data.frame or sf POLYGON data.frame.
Additionally, it offers all the R functions described in the official
documentation for converting QuadKeys to and from tiles, pixels, and
geographic coordinates.

data.frame column into an sf POLYGON data.frame.
