[LONGWY] Table of homogeneous areas describing a type of economic activity on an IRR.

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 aimed at reducing the negative consequences of flooding on human health, the environment, cultural heritage and economic activity.The objectives and requirements for implementation are set out in the Law of 12 July 2010 on a 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 data set is used to produce maps of the issues exposed at an appropriate scale.2007年10月23日发布的《关于洪水风险评估与管理的2007/60/EC号欧盟指令》（官方公报L系列第288号，2007年11月6日，第27页）对欧洲洪水防治战略产生了重要影响。该指令要求编制洪水风险管理计划，旨在减轻洪水对人类健康、自然环境、文化遗产及经济活动带来的负面影响。该指令的实施目标与要求，在2010年7月12日出台的《国家环境承诺法》（Law of 12 July 2010 on a national commitment for the environment，简称LENE）以及2011年3月2日的政令中予以明确。在此框架下，针对IRRs开展洪水及洪水风险制图的核心目标，是通过统一并客观化洪水暴露相关认知，为洪水风险管理计划（WRMs）的编制提供支撑。本数据集可用于制作符合适宜比例尺的洪水暴露要素专题地图。
