Abstract

Height Above Nearest Drainage (HAND) is an approach for estimating the vertical height of any point on the landscape from the nearest stream surface or bed. This dataset is based on the U.S. Geological Survey's National Elevation Dataset (NED) with 10-meter horizontal resolution, comprising raster data for the 331 HUC-6 units in conterminous U.S. (CONUS), excluding the five units of the great lakes. This was developed at the UIUC CyberGIS supercomputing facility, and is now archived at the UT Austin TACC (Texas Advanced Computing Center) for download.

To interactively select HAND data by HUC6 basin in either the Harvey or Irma hydrologic study area, use the Harvey Archive Story Map [http://arcg.is/001jje] or the Irma Archive Story Map [http://arcg.is/PSOKH] and click on the HAND tab. To directly browse this data for anywhere in CONUS, visit [https://web.corral.tacc.utexas.edu/nfiedata/].

Height Above Nearest Drainage (HAND) for USA

Height Above Nearest Drainage (HAND) is an approach for estimating the vertical height of any point on the landscape from the nearest stream surface or bed. This dataset is based on the U.S. Geological Survey's National Elevation Dataset (NED) with 10-meter horizontal resolution, comprising raster data for the 331 HUC-6 units in conterminous U.S. (CONUS), excluding the five units of the great lakes. This was developed at the UIUC CyberGIS supercomputing facility, and is now archived at the UT Austin TACC (Texas Advanced Computing Center) for download.

  • To interactively select HAND data by HUC6 basin for the Harvey or Irma hydrologic study area, use the [Harvey Archive Story Map] (http://arcg.is/001jje) or the [Irma Archive Story Map] (http://arcg.is/PSOKH) and click on the HAND tab.

HAND output metadata

Assume ${HUCID} denotes the HUC6 code for each unit below. This is the list of files in each HUC6 HAND directory:

  • ${HUCID}-wbd.shp HUC unit boundary shape file, extracted from USGS WBD
  • ${HUCID}-wbdbuf.shp HUC unit boundary shape file, extracted from USGS WBD (buffered)
  • ${HUCID}-flows.shp Flowline shape file, extracted from NHDPlus V21
  • ${HUCID}-inlets0.shp Inlets point shape file in the HUC unit. Native projection
  • ${HUCID}-inlets.shp Inlets point shape file in the HUC unit. EPSG:4269
  • ${HUCID}-weights.tif Weight grid of the rasterized inlet points
  • ${HUCID}.tif Clipped HUC unit DEM from USGS 3DEP 10m elevation dataset (buffered)
  • ${HUCID}fel.tif Pit-removed DEM; output of TauDEM pitremove
  • ${HUCID}p.tif D8 flow direction raster; output of TauDEM d8flowdir
  • ${HUCID}sd8.tif D8 slope raster; output of TauDEM d8flowdir
  • ${HUCID}ang.tif Dinfinity flow direction raster; output of TauDEM dinfflowdir
  • ${HUCID}slp.tif Dinfinity slope raster; output of TauDEM dinfflowdir
  • ${HUCID}ssa.tif Contributing area raster; output of TauDEM aread8
  • ${HUCID}src.tif Stream grid; output of TauDEM threshold (threshold=1)
  • ${HUCID}dd.tif Bufferred HAND raster; output of TauDEM dinfdistdown
  • ${HUCID}hand.tif HAND raster, buffer removed, final result
