National Hydrography Dataset
The US Geological Survey and the US Environmental Protection
Agency have been working for some years preparing a new
1:100,000 scale digital representation of the river network
of the United States called the National Hydrography Dataset.
More information on this project can be obtained from http://nhd.usgs.gov
. This effort is nearing completion and data are being
issued in 8-digital hydrologic cataloging unit packages
as they are completed. As these data become
available they will be an important base source of information
for the object model for rivers and watersheds being devised
by the GIS in Water Resources Consortium. Discussion
is ongoing as to how best to accomplish that objective.
