Workshop Information:

Topic: National Hydrography Dataset Applications Workshop. The workshop will include the availablility and potential uses of NHD within Virginia.

Format: The workshop will be delivered by lecture and hands-on computer using ArcGIS 9.2.

Instructor: Jeff Simley, National Hydrography Dataset Program Manager, USGS

Abstract: This class provides all of the basic information you need to exploit the power of the National Hydrography Dataset. The NHD was carefully designed for scientific applications and consists of many attributes and characteristics perfectly suited for geographic analysis using GIS. However, the data was designed to be simple enough for anyone to use, not just highly skilled GIS specialists. Thanks to this design, powerful applications can be developed with just one day's training. The class starts by looking at how others around the country are using the NHD. The NHD data structure is explored and applied to basic mapping techniques. The ability to navigate throughout the stream network is covered, opening up new approaches for conducting GIS. The data structure is explored in more detail revealing many new possibilities for network analysis. The important process of linking scientific data to the stream network is covered. These techniques, combined with network navigation, lead to cause and effect analysis allowing the scientist to discover how one event in the environment can impact another event. The importance of data change management, the added power of NHDPlus, and the role of ArcHydro are also covered.

The material will presented in such a manner as to allow higher level managers to attend just the first two or three hours and then leave. The remainder of the day will be oriented to GIS specialist with hands-on training to provide experience in using the NHD. However everyone is welcome for the entire day. You do not need to be a GIS expert to effectively use the NHD.

Skill Level: Basic knowledge of GIS.

Material: Each student will receive a copy of the workshop exercises.

Cost: None. Lunch is ‘on your own'

Registration: You can register using the online registration form or by contacting Jen Otey at the Virginia Geospatial Extension Program (540-231-9115/ jenotey@vt.edu). Class size is limited to 16 participants in Richmond and 20 in Reston. You will receive a confirmation email within 24 to 72 hours of registering.

**Due to limitation of class size this workshop is given preference to local/state/federal agency personnel who are working with the NHD and GIS.
