The U.S. Geological Survey mapping efforts continue making the transition from a historically based production model to the stewardship model. Strong partnerships with State and Federal partners are vital to the success of The National Map, and more specifically for this presentation, the National Hydrography Dataset (NHD). The NHD is a seamless dataset used for analysis, mapping, reporting, and tracking of water related issues. As with any real world dataset, changes are constantly occurring. In addition, much of the NHD is derived from sources over 20 to 40 years old. Updating the NHD takes advantage of new imagery and other sources of information. Because of their familiarity of the landscape, local users of the NHD are in the best position to provide updates, maintenance and feedback about the NHD. USGS is working with the OGRIP Ohio Hydrography Framework Task Force, including state agencies and local groups, on expanded stewardship to improve Ohio NHD. This presentation will cover the basics of the NHD and the Stewardship process.
