1km DEM dataset in the Heihe River Basin (2011)-National Tibetan Plateau Data Center

The DEM elevation model data set of 1km in heihe river basin generates DEM grid data based on China 1:250,000 digital contour line and elevation point data interpolation released by national basic geographic information center (http://ngcc.sbsm.gov.cn). The data includes Albers projection and longitude and latitude coordinates.A large amount of surface morphology information can be extracted from DEM, including the slope, slope direction and the relationship among cells of the watershed grid, which is an important source data for watershed research.

Data file naming and use method

File name: data is stored in GRID format, file name "heihe_1km_dem".
Data reading: Arcgis, Qgis and other remote sensing software can be used to open and read.
