Hydro basins level 3 Mekong

This dataset was obtained by delineating drainage basin boundaries from hydrologically corrected elevation data (HydroSHEDS and Hydro1K). Input data resolution is 15 arc-seconds between 60 N and 60 S latitude (based on SRTM), and 30 arc-seconds for higher latitudes (based on GTOPO30). The dataset consists of the following information: numerical code (MAJ_BAS), name (MAJ_NAME) and area (MAJ_AREA) of the major basin in square km.

Process Step This data was dissolved on level 3 for the Pfafstetter coding system. See http://www.hydrosheds.org/images/inpages/HydroBASINS_TechDoc_v1c.pdf for detailed documentation on this hierarchical system of attributing basin flow order and relationships. The dataset was trimmed to country boundaries according to ESRI's Global Administrative Database country boundaries data.
