This tabular data set represents the percent of Hydrologic Landscape Regions compiled for two spatial components of the NHDPlus version 2 data suite (NHDPlusv2) for the conterminous United States; 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network. This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID. The source data is the "Hydrologic landscape regions of the United States" produced by the United States Geological Survey (Wolock, 2003). Units are percent. The "Hydrologic landscape regions of the United States" are a 20-class classification scheme of noncontiguous regions (HLRs) built on the basis of similarities in land-surface...

This tabular data set represents the percent of land cover classes from the new generation of the 2016 National Land Cover Datasets for the years 2001, 2004, 2006, 2008, 2011, 2013, and 2016 compiled for two spatial components of the NHDPlus version 2.1 data suite (NHDPlusv2) for the conterminous United States; 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network. This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID. The source data is the "NLCD 2016 Land Cover Conterminous United States" datasets for the years 2001, 2004, 2006, 2008, 2011, 2013, and 2016 produced by the United States Geological Survey (Yang and others, 2018)....

This dataset was prepared by Phil Nott pnott@birdpop.org using ArcView 9.3 1. Merged NLCD canopy cover images (IMG) for NLCD superzones 1, 2, and 3. 2. Reclass value 127 to NoData 3. Aggregate 30m resolution to 990 meters with 33x aggregation = 990m resolution cells.
Calculated as the percentage cover within 990m-resoultion cells after 33x aggregation of NLCD 2001 canopy cover derivation whereby presence (1) was assigned to all 1,089 30m canopy cover cells in whichthe value exceeded zero.
This tabular data set represents the percent of land cover classes from the 2001 National Land Cover Dataset compiled for two spatial components of the NHDPlus version 2 data suite (NHDPlusv2) for the conterminous United States; 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network. This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID. The source data is the "National Land Cover Database 2001" produced by the United States Geological Survey (Homer and others, 2007). Units are percent. The "National Land Cover Database 2001" (NLCD 2001) is a 16-class (additional four classes in Alaska only) land cover classification scheme that...
