资源简介:
该数据集包含青藏高原1970s,1990,2000,2010年份大于1平方公里湖泊矢量数据。 湖泊水体边界根据Landsat MSS, TM, ETM+等影像目视解译而来。 数据类型为矢量数据,属性字段包括Area (km²)。 投影坐标系为Albers Conical Equal Area。 主要用于青藏高原湖泊、水文与气象变化研究。

This dataset contains vector data of lakes with an area greater than 1 km² on the Qinghai-Tibet Plateau in the 1970s, 1990, 2000 and 2010. The boundaries of lake water bodies were derived through visual interpretation of Landsat MSS, TM, ETM+ and other remote sensing images. The data type is vector data, and its attribute fields include Area (km²). The projected coordinate system is Albers Conical Equal Area. It is primarily utilized for studies on lake, hydrological and meteorological changes over the Qinghai-Tibet Plateau.
