Is there any place where I could find a GeoJSON describing the borders of the French departments, or do I have to convert a shapefile?

So do you already have a shapefile that you could convert? – Chad Cooper May 27 '13 at 14:32

I think I found one, but I'm having problem converting it. Source: http://professionnels.ign.fr/geofla#tab-3 – L. Sanna May 27 '13 at 14:33

Thank you very much, but I managed to convert it using http://ogre.adc4gis.com/. – L. Sanna May 27 '13 at 14:57

The OpenStreetMap’s French community are maintaining a rather exhaustive and accurate set of maps. Whether you’re a cartographer, a graphic designer or a developer, they’ve made it easy to reuse their work. As a matter of fact, from the OpenStreetMap’s OSM format, they’ve exported the maps to various formats such as Shapefiles, SVG, GeoJSON (to mention a few of them).
And the good news is that all their contributions are released on the French Open Data platform, under a ODbl license: https://www.data.gouv.fr/fr/organizations/openstreetmap/
So here it is: the French towns’ boundaries dataset: https://www.data.gouv.fr/fr/datasets/decoupage-administratif-communal-francais-issu-d-openstreetmap/

Someone exported French cities, departments and regions data as geojson, from the official National Geographic Institute (IGN). Free to use and open (Open Licence, compatible with CC-BY 2.0) : https://github.com/gregoiredavid/france-geojson
