While OpenStreetMap is rather good for cartographic information (and rendered maps) in urban areas of France, it is rather unsatisfactory in rural areas (except in the area where I live, where I improved the map!) The IGN local maps (1 : 25,000) are the reference maps for these, and include a high level of cartographic details while covering all of France. They are available online from the government-subsidized Géoportail, but are not part of the data made available through the French government open data effort (list of data available detailed here in French). In particular, while there exist an API to query information, it cannot be downloaded for offline use (as far as I am aware).

Where can I download high-precision cartographic data of France, with a good coverage of rural areas?

  • Could you make clearer what you target? I suppose it is something Géoportail does not offer, but what is it? Is it that Géoportail does not release machine-readable data?

  • @Vince Géoportail offers an API to query information, but no possibility to download machine-readable data for offline use. I have edited my question to make that clearer, thanks!

Data.gov provides geospatial data for areas around the world through NASA satellite imagery and other shared services. You can search for mapping data in France or anywhere else at http://geo.data.gov/geoportal/. You can also see a view of a new geospatial catalog on Data.gov below.

I've already entered the parameters for France, so you can see the data available. Just draw the bounding box where you need it to find any geospatial data that is available in that area.

  • Thanks for the link… there's no cartographic data listed on that site, unfortunately, so while it will be useful for other researches, it doesn't help for maps
