Territory: Population and buildings at hydrogeological risk 2018

The Dataset presents the number of resident citizens exposed to hydrogeological risk, the areas divided by hydraulic hazard, the buildings for residential use with one or more floors. The Higher Institute for Environmental Protection and Research (ISPRA), in order to obtain a map of landslide hazards throughout the national territory, proceeded to mosaic the hazardous areas of the Hydrogeological Structure Plans (PAI), by harmonizing the legends in 5 classes (very high hazards P4, high P3, medium P2, moderate P1 and areas of attention AA). The data collected concern the Municipality of Milan.本数据集涵盖受水文地质风险（hydrogeological risk）影响的常住居民数量、按水力灾害（hydraulic hazard）分级的区域，以及层数为一层及以上的住宅用建筑相关信息。 环境保护与研究高级研究所（Higher Institute for Environmental Protection and Research, ISPRA）为获取覆盖全国领土的滑坡灾害风险地图，对水文地质结构规划（Hydrogeological Structure Plans, PAI）中的灾害区域进行镶嵌拼接，并通过统一图例将其划分为5个等级：极高风险P4、高风险P3、中风险P2、低风险P1以及关注区域AA。 本次采集的数据均针对米兰市。
