Outlines of French regions on OpenStreetMap

Exports of French administrative division at regional level (regions) from OpenStreetMap produced in the vast majority from the cadastre.

This data comes from crowdsourcing carried out by the contributors to the OpenStreetMap project and is under ODbL license which requires identical sharing and the mandatory attribution mention must be “© OpenStreetMap contributors under ODbL license” in accordance with http://osm.org/copyright

This is a semi-automatic export with lighter and topologically verified geometries (no overlap). From 2016, the geometries are original, unsimplified.

Descriptive of the contents of “regions” files

Origin

The data comes from the OpenStreetMap cartographic database.
These were established from the cadastre made available by DGFiP on cadastre.gouv.fr.
In addition on Mayotte where the cadastre is not available on cadastre.gouv.fr, the route of the coasts was made from the aerial images of Bing.

Format

These files are available in shapefile format, in WGS84 projection with several levels of detail (until 2015):
— simplification at 5 m
— simplification at 50 m
— simplification at 100 m

The topology is retained during the simplification process (see: http://prev.openstreetmap.fr/blogs/cquest/limites-administratives-simplifiees)

Content

These files contain all the French regions, including the DOM and Mayotte.

For each region, the following attributes are added:

— code_insee: 2-digit INSEE code of the region (e.g. 42)
— name: name of the region (e.g. Alsace)
— Wikipedia: wikipedia entry (language code followed by the name of the article, e.g. en:Alsace)
— Wikidata: wikidata identifier of the region
— surf_km2: area area in km² on the WGS84 spheroid
