The U.S. Geological Survey (USGS) National Hydrography Dataset (NHD) and Watershed Boundary Dataset (WBD) are foundational datasets for scientists and citizens (and citizen-scientists!) in Federal, State, Tribal, local government, academia, and the private sector. The Hydrography Requirements and Benefits Study (HRBS) was designed by USGS and the Natural Resources Conservation Service to expand dataset managers’ understanding of hydrographic data and how these data can be improved. The study collected user requirements and associated benefits of fulfilling these requirements through online surveys and targeted in-person interviews. Respondents identified 420 Mission-Critical Activities reliant upon hydrographic data, ranging from water-quality monitoring and land management to real estate and recreation. Respondents reported over $18 billion in annual programs supported by hydrography data. This presentation will provide an overview of the results of the HRBS and discussion of various pilot activities and implementation scenarios, particularly those emphasizing better integration of hydrographic data with elevation data.
