Provides access to information from < https://api.gouv.fr/explorer/geoapi/> about French "Communes", "Departements" and "Regions".
This package requests informations from the French GeoAPI inside R — https://api.gouv.fr/explorer/geoapi/
Developped by Etalab, with La Poste, l’INSEE and OpenStreetMap, the GeoAPI API is a JSON interface designed to make requests on the French geographic database.
rgeoapi was developped to facilitate your geographic projects by giving you access to these informations straight inside R. With
rgeoapi, you can get any coordinate, size and population of a French city, to be used in your maps.
For an optimal compatibility, all the names (especially outputs) used in this package are the same as the ones used in the GeoAPI. Please note that this package works only with French cities.
Install this package directly in R :
