Summary
8.27 - updated with feedback from Mike J. ------------------------------------------------------- The National Hydrologic Geospatial Fabric Reference and Derived Hydrofabrics is a geospatial dataset used for hydrologic modeling, containing a network of connected rivers, lakes, and catchments. It consists of four different network representations: Reference Fabric, Refactored Fabric, target-size Hydrofabric, and Point of Interest (POI) Aggregated Hydrofabric. Each representation is designed to meet specific modeling needs by providing different levels of consolidation and aggregation of the hydrographic features. The dataset includes features and attributes representing hydrologic locations associated with observational data, cataloging, [...]

The National Hydrologic Geospatial Fabric Reference and Derived Hydrofabrics is a geospatial dataset used for hydrologic modeling, containing a network of connected rivers, lakes, and catchments. It consists of four different network representations: Reference Fabric, Refactored Fabric, target-size Hydrofabric, and Point of Interest (POI) Aggregated Hydrofabric. Each representation is designed to meet specific modeling needs by providing different levels of consolidation and aggregation of the hydrographic features. The dataset includes features and attributes representing hydrologic locations associated with observational data, cataloging, or reporting water data quantity or quality, and structures important to the storage and conveyance of surface water.
This child item contains features and attributes representing the The National Hydrologic Geospatial Fabric Refactored Hydrofabric. The Refactored Hydrofabric is a processed version of the reference hydrofabric where very small (less than about 1000 meters corresponding flowline length) catchments have been consolidated into larger ones and very large catchments (greater than about 10 kilometers corresponding flowline length) are split apart to limit size or to better represent important network outlets such as streamgages. When refactoring, network density is preserved and all hydrologic locations from the reference hydrofabric are preserved.
The item contains 21 Open Geospatial Consortium geopackages with refactored features for 21 NHDPlus Vector Processing Units (refactor_XX.gpkg), and one geopackage containing refactored features for all of CONUS (refactor_CONUS.gpkg). See the processing steps for specific refactoring details that produced the geopackages. The Refactored Hydrofabric is a processed hydrofabric derived from the reference hydrofabric where several network and spatial processing tasks are conducted to create more uniform distributions of flowline length and catchment area across the hydrofabric domain while preserving and enhacing points of interest defined in the reference fabric defined in the previous step.
