National Hydrologic Geospatial Fabric Refactored Hydrofabric
The National Hydrologic Geospatial Fabric Reference and Derived Hydrofabrics is a geospatial dataset of connected rivers, streams, lakes, catchments, hydrologic locations, and relevant attributes to support multi-scale and integrative hydrologic modeling and analysis.
This child dataset contains features and attributes representing the National Hydrologic Geospatial Fabric Refactored Hydrofabric. The Refactored Hydrofabric is a processed version of the Reference Hydrofabric with a more uniform distribution of catchment size. The complexity of different models requires flexibility to create different spatial levels of resolution and detail. Catchments with flowpath-lengths shorter than the user-specified minimum length threshold that increase data volume and compute cost but don't add hydrologic fidelity have been consolidated into larger ones. Catchments whose flowpath lengths are longer than the user-specified maximum flowpath-length threshold are split apart to provide uniform fidelity and better represent network outlets such as streamgages. When refactoring, key hydrologic locations like stream gages are preserved precisely, unless they are specified specifically as split events.
This item contains an Open Geospatial Consortium geopackage (gpkg) containing refactored flowlines, catchments, and other layers for all of Conterminous United States CONUS (refactor_CONUS.gpkg). See the processing steps for specific refactoring details.
