藏东南地区边界、地形数据（2000）

本数据集包括藏东南地区（Southeastern Tibetan Plateau, SETP）的矢量边界以及DEM、坡度、坡向、曲率等地形数据：
1、SETP_Boundary: 以帕隆藏布流域为中心，利用周边河网（包括雅鲁藏布江、怒江、澜沧江及各自支流）划分藏东南地区。该区域包括了念青唐古拉山东段、喜马拉雅山东段及横断山的西侧部分，是我国海洋性冰川分布最为集中的地区。
2、地形数据：基于NASA Earthdata数据中心提供的NASADEM数据，拼接生成了藏东南地区的DEM、坡度（SLOPE）、坡向（ASPECT）、剖面曲率（PROFC）和水体掩膜（SWB）数据。
3、山体阴影：基于藏东南地区的NASADEM进行表面分析，生产了高度角为45°的山体阴影数据。

This dataset contains the vector boundary of the Southeastern Tibetan Plateau (SETP) and topographic data including DEM, slope, aspect, curvature and others:
1. SETP_Boundary: Centered on the Parlung Tsangpo River Basin, the Southeastern Tibetan Plateau is delineated using surrounding river networks including the Yarlung Zangbo River, Nu River, Lancang River and their respective tributaries. This region covers the eastern section of the Nyainqentanglha Mountains, the eastern section of the Himalayas and the western part of the Hengduan Mountains, and is the most concentrated area for maritime glacier distribution in China.
2. Topographic data: Based on the NASADEM data provided by the NASA Earthdata Data Center, the DEM, slope (SLOPE), aspect (ASPECT), profile curvature (PROFC) and water body mask (SWB) data of the Southeastern Tibetan Plateau are mosaicked and generated.
3. Hillshade data: Surface analysis is conducted based on the NASADEM of the Southeastern Tibetan Plateau, and the hillshade data with an altitude angle of 45° is produced.
