Dataset Direct Download Service (WFS): Area exposed to one or more hazards on the map of hazards produced in the development of R111-3 subsidence and collapse of Reims sector cavities.

The hazards causing the risk are contained in hazard documents which are included in the presentation report and annexed to R111-3 cavities. These documents are used to map the different intensity levels of each hazard taken into account this R111-3. Each area exposed to one or more cavity hazards existing in this spatial dataset is linked with its GASPAR code: 51DDT20090009. Genealogy: The so-called geotechnical risk pre-zoning hazards are developed from the overlay of all the hazards of the various subsidence-fall risks of underground cavity based on hazard data and risk probability established by the BRGM. Each of the geographic areas of R111-3 subjected to one or more hazards can then be extracted by overlaying zone. Each exposed area, possibly recouped, is then described by a record in this resource.
