Simple download service (Atom) of the dataset: Table listing flood risk maps produced on a given IRR.

A series of spatial data produced by the GIS High Flood Risk Land Flood Directive (TRI) of the French Metropolis and mapped for reporting purposes for the European Flood Directive.
European Directive 2007/60/EC of 23 October 2007 on the assessment and management of flood risks (OJ L 288, 06-11-2007, p. 27) influences the flood prevention strategy in Europe. It requires the production of flood risk management plans to reduce the negative consequences of flooding on human health, the environment, cultural heritage and economic activity.
The objectives and implementation requirements are set out in the Law of 12 July 2010 on the National Commitment for the Environment (LENE) and the Decree of 2 March 2011. In this context, the primary objective of flood and flood risk mapping for IRRs is to contribute, by homogenising and objectivating knowledge of flood exposure, to the development of flood risk management plans (WRMs).
This dataset is used to produce flood surface maps and flood risk maps that represent flood hazards and issues at an appropriate scale, respectively. Their objective is to provide quantitative evidence to further assess the vulnerability of a territory for the three levels of probability of flooding (high, medium, low).

本数据集为法国大都会地理信息系统（Geographic Information System, GIS）高洪泛风险土地洪泛指令（TRI）生成的系列空间数据，且针对《欧洲洪泛指令》的报告需求完成了制图处理。
2007年10月23日发布的欧盟2007/60/EC号指令《关于洪泛风险评估与管理》（《欧盟官方公报》L 288，2007年11月6日，第27页），为欧洲洪泛防治战略确立了基本框架。该指令要求编制洪泛风险管理计划，以降低洪泛对人类健康、生态环境、文化遗产及经济活动产生的负面影响。
相关目标与实施要求已在2010年7月12日颁布的《国家环境承诺法》（LENE）以及2011年3月2日的政令中予以明确。在此框架下，针对受影响区域（IRRs）的洪泛与洪泛风险制图工作的核心目标，是通过统一并客观化洪泛暴露相关认知，助力洪水风险管理计划（WRMs）的编制。
本数据集可用于制作洪泛范围图与洪泛风险图，二者分别以适宜比例尺表征洪泛灾害与相关风险。其目标在于提供量化依据，以进一步评估某一区域在高、中、低三种洪水发生概率等级下的脆弱性。
