Spatial data set contained in the Medium Eure Flood Risk Prevention Plan file

Risk Prevention Plans (RPPs) are the key government instrument for risk prevention. Their objective is to control development in areas at risk.

The development of a risk prevention plan generates a set of spatial data organised into several data sets. The same PPR may include spatial datasets containing:

PPR’s main encompassing perimeters (study perimeter, prescription perimeter, regulated perimeter);

— restricted areas of the plan once approved. RPP regulations generally distinguish between ‘construction ban areas’, so-called ‘red areas’, where the hazard level is high and where the general rule is the construction ban; ‘areas subject to requirements’, known as ‘blue zones’ where the hazard level is medium and projects are subject to requirements adapted to the type of issue and areas not directly exposed to risks but subject to prohibitions or prescriptions;

— hazard areas represented on the map of hazards used for risk analysis by crossing with the stakes, specifying for each zone the level of the hazards to which it is exposed;

issues (persons, assets, activities, cultural or environmental heritage elements) threatened by a hazard and likely to be affected or damaged by it;

— origins of risk, i.e. the entity of the real world which, through its presence, represents a potential risk. This entity may be characterised by a name, a reference to an external object or a geographical object that locates the actual entity causing the risk.

本数据集为收录于《中厄尔省洪水风险防治规划》文件中的空间数据集。

风险防治规划（Risk Prevention Plans, RPPs）是政府开展风险防治的核心工具，其目标为管控高风险区域内的开发活动。

编制风险防治规划会生成一系列空间数据，并进一步整合为多个数据集。同一份风险防治规划可包含以下类型的空间数据集：
风险防治规划的核心覆盖范围（研究范围、管控范围、合规范围）；
—— 规划获批后的限制管控区域。风险防治规划的管控规则通常会区分‘建设禁建区’（又称‘红色区域’），此类区域灾害等级较高，通用规则为禁止建设；以及‘合规管控区’（又称‘蓝色区域’），此类区域灾害等级中等，项目需根据具体风险类型适配管控要求，此外还包括未直接暴露于风险之下，但仍需遵守禁令或管控要求的区域；
—— 用于风险分析的灾害地图上标注的灾害风险区，需通过与管控点位叠加分析，明确各区域所承受的灾害等级；
受灾害威胁、可能遭受影响或损毁的承灾对象（包括人员、资产、生产活动、文化或自然遗产要素等）；
—— 风险源，即现实世界中因存在而构成潜在风险的实体。该实体可通过名称、外部对象引用或用于定位实际致险实体的地理对象进行标识。
