中国地表水体、大坝、水库和湖泊数据集(2019年)
收藏资源简介:
该数据集基于2019年Landsat ETM+/OLI遥感影像、谷歌地球高分影像以及谷歌地球云计算引擎,获得中国2019年水体分布数据,并将大面积的水体斑块(面积>1km2)分为湖泊和水库两大类,并标识出水库对应的水坝信息,形成了完整可靠的中国地表水体、大坝、水库和湖泊数据集。 该数据包含3个shp矢量文件,“China_large_dams.shp”为全国水坝数据,“China_large_lakes.shp”为全国湖泊(面积>1km2)数据,“China_large_reservoirs.shp”为全国水库(面积>1km2)数据。
This dataset is constructed based on 2019 Landsat ETM+/OLI remote sensing imagery, high-resolution Google Earth imagery, and the Google Earth Engine. It derives the 2019 water body distribution dataset of China, classifies large water body patches with an area greater than 1 km² into two categories: lakes and reservoirs, and identifies the associated dam information for each reservoir, thereby creating a comprehensive and reliable dataset covering China's surface water bodies, dams, reservoirs, and lakes. This dataset includes three shapefile vector files: "China_large_dams.shp" stores the national dam dataset, "China_large_lakes.shp" contains the national lake dataset (area > 1 km²), and "China_large_reservoirs.shp" holds the national reservoir dataset (area > 1 km²).
