This data set is extracted according to the mask of Sichuan Tibet line and surrounding areas according to the data of 1:250000 river water system in three-level watershed of Qinghai Tibet Plateau (2012), which is vector data. Geographic coordinate system: GCS_ China_ Geodetic_ Coordinate_ System_ 2000； Spatial accuracy: scale 1:250000. The data can be opened and used by ArcGIS, envi or other geographic information systems and remote sensing software. Water system can be used to divide small watersheds, determine the watershed area, and calculate the characteristic parameters of water system, such as river network density, river system development coefficient, river system non-uniformity coefficient, etc. it plays an important role in the field of hydrology.

File naming and required software

Data naming: the water system distribution data (2012) in the 1:250000 three-level watershed division along the Sichuan Tibet line and its surrounding areas are stored in the format of structural type vector.
Reading method: the data can be opened and used by ArcGIS, envi or other geographic information systems and remote sensing software. In the process of reading, a file in SHP format will be generated, and the displayed SHP file is the file.
