Outlines of French boroughs from OpenStreetMap

Exports of the French administrative division at the level of the arrondissements resulting 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).

###Descriptive of the contents of the “rounding” 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, it is the limits of the GEOFLA of IGN that have been used as well as the plot of the coasts from the aerial images of Bing.

**Format**

These files are offered in shapefile format, in WGS84 projection with several levels of detail:

— simplification at 5 m
— simplification at 50 m
— simplification at 100 m

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

**Content**

These files contain all the French boroughs, including the DOMs, but without Mayotte.

For each district, the following attributes are added:

— insee_ar:

— Wikipedia:
