This service is in line with the BRGM's new policy on open data and open knowledge, which is evolving with the requirements of the regulatory context concerning public data access, distribution and reuse in France and Europe. As the French geological survey, the BRGM is committed in particular to the national Open Data plan.
Geological maps as key decision-making tools
Geological maps are essential aids to decision-making for public authorities, planning agencies and consultancies in many fields of activity, including spatial planning, mineral prospecting, groundwater prospecting and protection, pollution control, natural risk prevention and the characterisation of local areas. They are also key learning aids for geoscience teachers and for everyone looking to understand the world around us.
Other digital geological maps, of Overseas France in particular, will similarly be made available in the coming months.
