资源简介:
第三极1:100万水系数据集包括:第三极地区不同等级的线型水系(Tibet_water_line)、多边形水系(Tibet_water_poly)矢量空间数据及相关属性数据:名称(Name)、类型(Type)、水系长度(leng)、水系面积(Area)。
数据来自1:100万ADC_WorldMap全球数据集,数据经过拓扑,入库是全面、最新和无缝的地理数字数据。
世界地图坐标系统是经纬度,D_WGS_1984基准面。
The Third Pole 1:1,000,000-scale hydrological dataset includes vector spatial data and their associated attribute data for linear water systems (Tibet_water_line) and polygonal water systems (Tibet_water_poly) of different grades in the Third Pole region. The associated attribute data include Name, Type, water body length (leng), and water body area (Area). This dataset is derived from the 1:1,000,000-scale ADC_WorldMap global dataset. The data has been topologically processed, and the archived geospatial digital data is comprehensive, up-to-date and seamless. The coordinate system of the dataset is latitude-longitude, using the D_WGS_1984 geodetic datum.
