River networks dataset at 1:1000 000 in Sanjiangyuan region (2017)- A Big Earth Data Platform for Three Poles

This data originates from the National Geographic Information Resources Catalogue Service System, which was provided free to the public in November 2017. We have spliced and cut the source of the three rivers as a whole, so as to facilitate the use of the study of the source area of the three rivers.

This data set is composed of 1:1 million water coefficient data in Sanjiangyuan area, including three layers: water system surface (HYDA), water system line (HYDL) and water system point (HYDP). The water system surface (HYDA) includes lakes, reservoirs and double-line rivers; the water system line (HYDL) includes single-line rivers, ditches, river structure lines; and the water system point (HYDP) includes springs and wells.
