Summary

The Geospatial Fabric version 1.1 (GFv1.1 or v1_1) is a dataset of spatial modeling units covering the conterminous United States (CONUS) and most major river basins that flow in from Canada. The GFv1.1 is an update to the original Geospatial Fabric (GFv1, Viger and Bock, 2014) for the National Hydrologic Modeling (NHM). Analogous to the GFv1, the GFv1.1 described here includes the following vector feature classes: points of interest (POIs_v1_1), a stream network (nsegment_v1_1), and hydrologic response units (nhru_v1_1), with several additional ancillary tables. These data are contained within the Environmental Systems Research Institute (ESRI) geodatabase format (GFv1.1.gdb).

Purpose

The purpose of the dataset is to extend the GFv1 domain in support of the NHM by deriving modeling units (the Transbounday Geospatial Fabric [TGF]) in major conterminous United States-Canadian transboundary basins that match the scale of detail and information in the GFv1 and to update the GFv1 with these new units into a seamless dataset (GFv1.1).
