Comparing the Geospatial Fabric with NHD
Geospatial Fabric
Catchments, NHRU, segments, POI
segments are subset of NHD
NHRU are smallest
Compared to HUC12
NHD vs NHD+ vs Segments
Not all NHRU have segment
segment is subset of NHD - better for us to use NHD and do our own pruning
Schema - Geospatial Fabric
Schema - NHD
Schema - NHD+ HR
