PPRL de La Faute-sur-Mer — Current Reference Costs of the Plan for the Prevention of Predictable Natural Hazards Littoraux — Vendée

The reference rating corresponds to the altitude of the body of water modeled at the right of an existing project or construction. It is displayed in m NGF-IGN 69, i.e. in meters in the official grading network in metropolitan France which is attached to the Marseille tide gauge. The reference rating therefore does not correspond to a water height but rather to the altimetry of the water body. The water height corresponds to the difference between the reference rating and the altimetry rating of the natural terrain. __Origin__ COVADIS standard of the digital data of the PPRn of the departments of the Aquitaine region. __Partner organisations__ DDTM Vendée, BARBERA Francis __Links annexes__ * [XML metadata view](http://ogc.geo-ide.developpement-durable.gouv.fr/csw/all-dataset?REQUEST=GetRecordById&SERVICE=CSW&VERSION=2.0.2&RESULTTYPE=results&elementSetName=full&TYPENAMES=gmd:MD_Metadata&OUTPUTSCHEMA=http://www.isotc211.org/2005/gmd&ID=fr-120066022-jdd-eb300ee9-7a08-48a6-b561-09567989ad0f) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/3a8a7f3664d1efc7c7de954ac1c75e4915e8fe37)
