The drainage basins distributed with the HYDRO1k data set suite are derived using the vector stream networks along with the flow direction data set. Each polygon in the basin data set has been tagged with a Pfafstetter code uniquely identifying each sub-basin. A detailed description of the coding scheme can be found in Verdin. Additional attributes defining the characteristics of each sub-basin have been developed. These are described in the Readme file. These data are available in an ARC/INFO export format and in shapefile format.
