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
