Area exposed to one or more hazards on the map of hazards produced in the context of the development of the plan to prevent the risk of subsidence- collapse of cavities area of Châlons-en-Champagne.
Description
The hazards causing the risk are contained in hazard documents which can be inserted in the presentation report or annexed to the PPRN cavities. These documents are used to map the different intensity levels of each hazard considered in the risk prevention plan.
Each area exposed to one or more cavity hazards in this spatial dataset is linked with its GASPAR code: 51DDT20090008.
Genealogy:
The so-called synthetic hazards are developed from the superposition of all the hazards of the different risks of subsidence- collapse of underground cavities from the hazard data established by the BRGM. Each of the geographic areas of the PPRN cavities subjected to one or more hazards can be extracted by overlaying zone. Each exposed area, possibly recouped, is then described by a record in this resource.
