Plan for the prevention of natural hazards of movement of the ground — Commune de Brassac — On-off issue — Department of Tarn-et-Garonne

In general, the stakes are people, property, activities, elements of cultural or environmental heritage, threatened by hazards and likely to be affected or damaged by it. The sensitivity of a hazard issue is called “vulnerability”. This class d' object includes all the issues that have been taken into account in the PPR study. An issue is a dated object whose consideration is based on the object of the PPR and its vulnerability to the hazards studied. A PPR issue can therefore be taken into account (or not) depending on the type or types of hazard treated. These elements form the basis of knowledge of the soil required for the Â#x27; development of the PPR, in the zone d’#x27; study or near it, at the date of #x27; analysis of the issues. The data of #x27; Issues represent a photograph (fixed and not exhaustive) of assets and people exposed to hazards at the time of #x27; development of the risk prevention plan. This data is not updated after PPR approval. In practice they are no longer used: the stakes are recalculated as needed with up-to-date data sources. __Origin__ The geometric modeling of ' entity at ' origin of risk depends on the type of risk, the context of the PPR, the nature of the generator and its modeling in the data source or geographical repository from which it originates. For example, a water course may be represented by a polygon or a polyline according to its size and width, an ICPE by a point (if the location of its enclosure is not known) or by a polygon (especially from the grey area of the PPR).The geometry of this class d' objects is optional when: — this geometry is already carried by an object d'a geographical repository or d' an external data source, to which it is then recommended to refer to the ' help of its identifier (and thus avoid unnecessary duplication);- it does not exist because the origin of the risk cannot be precisely defined or localised (c' is the case of certain risks such as, for example, earthquakes, avalanches, sea submersions...)Nevertheless, as it is in practice rare to benefit from stable references to external objects, the geometry of l' origin of the risk will often result from the duplication of that of the #x27; object representing the #x27; origin of the risk. __Partner organisations__ DDT Tarn-et-Garonne __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-1b367c05-f459-431d-90f0-99dfc9ee5a8c) * [COVADIS data standard: One-time issue of a PPRN](http://geostandards.developpement-durable.gouv.fr/afficherPageStandard.do?jeu=N_ENJEU_PPRN_AAAANNNN_P) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/2231026282e5de0c216c06517dde353518bf9347)
