quadkeyr review
A free, open-source R package for quadkey and tiled-coordinate conversions.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
For R developers who need to index or address web-map tiles, quadkeyr provides functions for converting between longitude/latitude coordinates, tile coordinates, zoom levels, and Bing Maps-style quadkey strings. It is an open-source R package distributed for self-hosted or desktop use, aimed at scripts and applications rather than interactive GIS authoring. Its value is concentrated in tile addressing: teams looking for a broader GIS workspace will need another tool for the rest of their mapping work.
The package’s scope is deliberately narrow. Its listed functions cover converting geographic coordinates to tile coordinates, converting tiles to quadkeys, and reversing quadkeys back to tile coordinates, with zoom-level parameters for tiled maps. That makes it relevant when a workflow needs to derive or interpret tile identifiers in R. It does not provide spatial analysis, raster support, web mapping, dashboards, or mobile apps, so it should not be treated as a general-purpose GIS platform.
quadkeyr is free and open source, with documentation and reference material published by rOpenSci. There is no hosted application described; deployment is package-based for local use. This suits developers comfortable incorporating R utilities into their own scripts and applications, including solo users through enterprise teams. Choose it for quadkey conversions without a commercial plan; choose a broader GIS product if you need analysis, raster workflows, or interactive map authoring alongside tile utilities.
