Ask about a specific address or cadastral parcel: natural and industrial risks (flood, clay shrink-swell, radon, seismic, polluted sites), urban-planning zoning, recent property sales, energy ratings, noise, fibre and mobile coverage, protected areas and heritage. D\u00e9partements, overseas included, and r\u00e9gions come with their own statistics.\n\nUseful before moving, buying or renting, for due diligence on an address, to compare towns, and for local journalism or research on public statistics.\n\nLimitations: France only (metropolitan France and the overseas d\u00e9partements). Read-only: it never changes anything. Owner names are not part of the public data and are never returned. Figures come from the latest official release of each source, which can be one to three years old. All data is under the Etalab Open Licence 2.0.\n\nConnecting asks you to sign in to a La Grande Carte account (email and password, or Google).",
