青藏高原流域边界数据集(2016)
收藏资源简介:
青藏高原流域边界数据集使用2000年的航天飞机雷达地形任务收集的干涉合成孔径雷达SRTM DEM 数据、参考河流、湖泊等水系辅助数据,利用arcgis水文模型,分析、提取河网,将青藏高原划分为AmuDayra、Brahmaputra、Ganges、Hexi、Indus、Inner、Mekong、Qaidam、Salween、Tarim、Yangtze、Yellow等12个子流域。其中研究区外围边界是基于2500米等高线。
The Qinghai-Tibet Plateau watershed boundary dataset uses SRTM DEM data collected by the 2000 Shuttle Radar Topography Mission (SRTM), which adopts Interferometric Synthetic Aperture Radar (InSAR) technology, together with auxiliary hydrological data including reference rivers and lakes. It applies the ArcGIS hydrological model to analyze and extract the river network, thus dividing the Qinghai-Tibet Plateau into 12 sub-watersheds: Amu Darya, Brahmaputra, Ganges, Hexi, Indus, Inner, Mekong, Qaidam, Salween, Tarim, Yangtze, and Yellow. The peripheral boundary of the study area is defined based on the 2500-meter contour line.
