The National Hydrography Dataset is a partnership
between the USGS and over 50 government agencies to produce a
GIS dataset of the Nation's surface water. This dataset is designed
to allow the analysis of water related events within the surface
water network, such as the upstream/downstream relationship of
permitted discharges, water quality monitoring stations, and drinking
water intakes. The NHD provides the surface water geospatial framework
upon which the events can be addressed, and related through the
flow network. The NHD is also designed for use in mapping, allowing
the user to construct customized surface water maps. The dataset
is available nationwide at 1:100,000-scale, and is nearing completion
at 1:24,000-scale. The NHD is designed for continuous maintenance
through a stewardship program made up of data users and the USGS.
This all-day workshop will give the user a comprehensive overview
of the NHD enabling them to use the NHD in a variety of GIS applications.
The workshop will cover: (1) How the NHD is used by various users
across the Country, (2) Characteristics of the NHD, (3) Mapping
with the NHD, (4) Flow navigation, (5) Linear Referencing, and
(6) Network analysis.
