HydroBasins
HydroBASINS is a global, vectorized layer of hierarchically nested sub-basin boundaries. It provides seamless coverage and uses the 'Pfafstetter' coding system offering a 12 scales breakdown to enable analysis of catchment topology and up/downstream connectivity. Extracted from HydroSHEDS at 15 arc-second resolution, this layer is part of the HydroATLAS collection.

Cautions
The polygon data sets of HydroBASINS are distributed in ESRI ‘shapefile’ format (ESRI 1998). Each HydroBASINS shapefile consists of five main files (.dbf, .sbn, .sbx, .shp, .shx). Additionally, basic metadata information is provided in XML format (.xml). Projection information is provided in an ASCII text file (.prj). All shapefiles are in geographic (latitude/longitude) projection, referenced to datum WGS84.
