Installation instructions:
NHDPlusV2 data is distributed in compressed files created by 7-Zip
(compression software) with a ".7z" extension. While 7-Zip can create
files in standard Zip format, the NHDPlusV2 data is stored in a special
7-Zip format which creates even smaller compressed files.
This helps preserve disk space and shorten download times.
7-Zip, and other zipping utilities that support ".7z" files, may be used
to uncompress the NHDPlusV2 data. 7-Zip is a free utility available at:
http://www.7-zip.org/download.html.
