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](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. More info: [http://prev.openstreetmap.fr/36680-communes](http://prev.openstreetmap.fr/36680-communes) **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](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 ### History — **01-01-2017**: version based on the municipal division OSM as of 01-01-2017 including the merger of 566 communes into 178 new municipalities. — 01-01-2018: version based on OSM communal cutting at 01-01-2018 (marginal change in geometry) Predecent versions available on: [http://osm13.openstreetmap.fr/~cquest/openfla/export/](http://osm13.openstreetmap.fr/~cquest/openfla/export/) If you have any questions about these exports, you can contact [e-mail] See also: — [cards in SVG format](https://www.data.gouv.fr/fr/dataset/cartes-des-regions-et-departements-issus-d-openstreetmap) — [contours of the French municipalities](https://www.data.gouv.fr/fr/dataset/decoupage-administratif-communal-francais-issu-d-openstreetmap) — [contours of EPCI 2014](https://www.data.gouv.fr/fr/dataset/contours-des-epci-2014) and [Contours des EPCI 2013](https://www.data.gouv.fr/fr/dataset/contours-des-epci-2013) — [contours of the French arrondissements](https://www.data.gouv.fr/fr/dataset/contours-des-arrondissements-francais-issus-d-openstreetmap) — [contours of the French departments](https://www.data.gouv.fr/fr/dataset/contours-des-departements-francais-issus-d-openstreetmap) and [SVG maps of the departments](https://www.data.gouv.fr/fr/dataset/cartes-des-regions-et-departements-issus-d-openstreetmap)
