30 arc-second DEM data of the Heihe River Basin (2009)

30 arc-second DEM data of the Heihe River Basin (2009)


This data is based on the DEM data generated by 1:250,000 digital contour lines and elevation points in China released by national basic geographic information center, and the DEM data set of heihe river basin is generated by the nearest neighbor method resampling method of ARCGIS spatial analysis module with a spatial resolution of 30 SEC.


File naming and required software

File name: the data is stored in GRID format. The files are divided into Albers and geographic folders. The file names are "dem30secalb" and "dem30secgeo".
Data reading: Arcgis, Qgis and other remote sensing software can be used to open the reading, in the form of images.
