(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...

Parameter values for the Precipitation Runoff Modeling System (PRMS) using the National Hydrologic Modeling (NHM) infrastructure. The contents of the attached zip folder are a direct download from the USGS bitbucket repository titled National Hydrologic Model Parameter Database (NhmParamDb) (https://my.usgs.gov/bitbucket/projects/MOWS/repos/nhmparamdb/browse). The NhmParamDb is stored using a Git version control system, which tracks modifications to the master dataset through 'commits'. Each commit has a unique code to allow for retroactive identification of any given component of the repository. The specific attributes of the download contained in this release are: Date: May 8, 2017 Commit: 6ccc41d5688 Filename:...
The output data in this collection is essentialy identical to that in version 1.0, but is more formally packaged. It includes reference to source data sets and software used to derived the output. Input data include two routing parameters from the NHM archive ("paramdb") of PRMS parameters: hru_segment_nhm and tosegment_nhm. hru_segment_nhm defines the stream segment to which the fluxes from each HRU arrives. tosegment_nhm defines the next downstream segment in the Geospatial Fabric. The values for both of these parameters reflect the national stream segment identifiers (as opposed to region-specific equivalents, hru_segment and tosegment). The software is provided in order to allow regeneration of the headwater...
