Summary

(Hyperlink to Official Landing Page for Geospatial Fabric products) The Geospatial Fabric provides a consistent, documented, and topologically connected set of spatial features that create an abstracted stream/basin network of features useful for hydrologic modeling.The GIS vector features contained in this Geospatial Fabric (GF) data set cover the lower 48 U.S. states, Hawaii, and Puerto Rico. Four GIS feature classes are provided for each Region: 1) the Region outline ("one"), 2) Points of Interest ("POIs"), 3) a routing network ("nsegment"), and 4) Hydrologic Response Units ("nhru"). A graphic showing the boundaries for all Regions is provided at http://dx.doi.org/doi:10.5066/F7542KMD. These Regions are identical to those used [...]

Purpose

The purpose of these data is to enable research and application of hydrological simulation models for the United States at regional and national scales. These data provide geographic features that have been derived using a nationally consistent methodology. Hydrologic model parameters can be derived from the Geospatial Fabric Features.
