COVADIS data standard provides a framework for the digital storage of geographical data within French Risk Prevention Plans (RPPs). This specific dataset, DDT 48, applies the standard to the flood risk prevention plan for the municipality of Barjac. The data was last updated by the Bureau de Recherches Géologiques et Minières on March 22, 2019.
Use Cases
