Hydro basins level 6: Mekong

Hydro-basins provide hydrographic data layers that allow for the derivation of watershed boundaries for any given location based on the near-global, high-resolution SRTM digital elevation model. Watersheds were delineated in a consistent manner at different scales, and a hierarchical sub-basin breakdown was created following the topological concept of the Pfafstetter coding system (Verdin & Verdin 1999). The resulting polygon layers are termed HydroBASINS and represent a subset of the HydroSHEDS database. There are 12 levels. Level 6 represents major river systems from headwaters to coast. This version is sourced from FAO.

Positional Accuracy No known issues with accuracy.
Logical Consistency No known issues with logical consistency.
Completeness The dataset is a subset of the gloabal Hydrosheds data and is complete.
Process Step This data was dissolved on level 3 for the Pfafstetter coding system. See 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.
