High-quality hydrographic data are critical to a broad range of government and private applications. Resource management, infrastructure planning, environmental monitoring, fisheries management, and disaster mitigation all depend on up-to-date, accurate, and high-quality hydrographic data. The U.S. Geological Survey National Geospatial Program has begun a series of virtual seminars to highlight the uses of hydrographic data. These seminars are intended to share success stories from users who have solved real world problems using hydrographic data, provide information about the National Hydrography Dataset and related products, and provide a virtual forum for users, similar to what might be encountered in a conference setting. The first seminar was held on April 9, and covered how the ICWater tool was used to respond to the January 2014 Elk River chemical spill in West Virginia. The second seminar, to be held on May 21 at 2 PM ET, will feature *Ed Clark* of the National Weather Service presenting "*The* *National Flood Interoperability Experiment - Leveraging USGS Elevation and Hydrography data to define a common framework for integrating water resource datasets."* The NFIE utilizes spatial data and new communications standards that simplify the exchange of water information among disparate producers and consumers, as well as integrating cutting-edge hydrologic modeling and analysis techniques from the research community. An abstract and speaker biography are available at http://nhd.usgs.gov/HydrographySeminarSeries.html These seminars will be presented every 6 to 8 weeks, featuring applications and speakers from different disciplines. Connections are limited and pre-registration is required.
