While doing research on points of interest, I coded a new R tool to retrieve research data from Google Maps. Google Maps is a great source of points of interest data, but it heavily limits the number of results. This R script recursively generates sub-queries, until all POIs have been retrieved. The results are generated in JSON and geopackage format.

Note that this tool has been developed for non-profit academic research. As always, suggestions and feedback are welcome.
