Simulated Topological Network (STN) of Digitized River Networks for the World Water Development II

The global Simulated Topological Network at 30-minute spatial resolution (STN--30) represents rivers as a set of spatial and tabular data layers derived from a 30-minute spatial resolution (STN--30) represents rivers as a set of spatial and tabular data layers derived from a 30-minute flow-direction grid. This dataset includes many different attributes (i.e., basin area, length, distance to river mouth, etc.). These datasets represents an update of VC6rC6smarty et al. (2000a, b) using methods developed in Fekete et al. (2001). Also, the continental Simulated Topological Network files at 6-minute spatial resolution (STN--6) represent rivers as a set of spatial and tabular data layers derived from a 6-minute flow-direction grid developed from Fekete et al. (2001). Potential flow direction is in this archive. Hydro1K EDC flow direction datasets served as the basis of these networks and were then manually corrected to match a vector overlay of rivers. Continents represented are: Africa Australasia Asia Europe North America South America
