黄山市潜在淹没区不透水面数据集(2010）

黄山市2010年潜在淹没区不透水面数据集。该数据基于新安江水文站警戒水位，利用SRTM DEM数据，在面状数字高程模型上提取黄山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，得到黄山市潜在淹没区范围。在黄山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，提取黄山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 of Potential Flooded Areas in Huangshan City (2010).
This dataset is constructed based on the warning water level of the Xin'anjiang Hydrological Station, using SRTM DEM data to extract the spatial extent of Huangshan City that is equal to or below the warning water level from the raster digital elevation model. Meanwhile, combined with the distribution data of the main stream water system of the Yangtze River, disconnected regions within the area below the warning water level are eliminated, and the basin boundary is applied to derive the final potential flooded area extent of Huangshan City.
Based on the derived potential flooded area extent of Huangshan City, the impervious surface area within the administrative region of Huangshan City is extracted using the 2010 remote sensing monitoring data of land use status in the Yangtze River Basin.
Specifically, the areas of urban construction land, rural residential areas and other construction land in the land use dataset are extracted as impervious surfaces.
