DESCRIPTION:

The global Simulated Topological Network at 30-minute spatial resolution (STN--30 version 6.01) 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.). This dataset represents an update of Vörösmarty et al. (2000a, b) using methods developed in Fekete et al. (2001).

The preview image show flow direction for potentially flowing river networks, Vörösmarty and Meybeck., 2004).
