六安市潜在淹没区不透水面数据集(2010）

六安市2010年潜在淹没区不透水面数据集。该数据基于佛子岭水文站警戒水位，利用SRTM DEM数据，在面状数字高程模型上提取六安市等于及小于警戒水位线的空间范围。同时，结合长江干流水系分布数据，排除小于警戒水位范围内的不连通区域，利用流域范围，得到六安市潜在淹没区范围。在六安市潜在淹没范围基础上，利用长江流域土地利用现状遥感监测数据2010年数据，提取六安市区域属于不透水面的范围。提取土地利用数据中心城镇建设用地、农村居民地与其他建设用地范围作为不透水面。

Impervious Surface Dataset for Potential Flooded Areas in Lu'an City (2010). This dataset is developed based on the warning water level of the Foziling Hydrological Station and SRTM DEM data, by extracting the spatial extent within Lu'an City that is equal to or lower than the warning water level from the digital elevation model. Meanwhile, in combination with the distribution data of the Yangtze River mainstream water system, disconnected regions within the area below the warning water level are excluded, and the watershed boundary is employed to derive the potential flooded area scope of Lu'an City. Based on this potential flooded area scope, the impervious surface extent within Lu'an City is extracted using the 2010 Yangtze River Basin land use status remote sensing monitoring data. Specifically, areas corresponding to urban construction land, rural residential areas and other construction lands in the land use dataset are classified as impervious surfaces.
