Building Partnerships for Data Stewardship; The California National Hydrography Dataset Program

Maps can only be as good as the data they are built upon, and data is only as useful if it is good data. One of the foundations of the National Map is the National Hydrography Dataset (NHD). The digital version of the blue lines on USGS topographic quad maps has evolved into a hearty dataset serving as the geospatial framework for the mapping, modeling, and planning of the nation’s water resources. The NHD is maintained in a rigorous process that utilizes technical mapping standards, custom tools, and a stewardship-maintenance system. Through this process, coordination among data stewards, editors, and end-users is required in order to achieve standardization within the NHD and maximize utility for hydrologic modeling, environmental assessment, map making, and beyond. In California, the state’s Department of Water Resources recently assumed the role of steward for the NHD with the goal of making a good dataset better and more useful for the people of the state and the nation. This presentation explores the partnership between CA DWR, the US Geological Survey, the Center for Geographical Studies (CGS) at CSU, Northridge, and the Geographical Information Center (GIC) at CSU, Chico that launched the NHD Stewardship Program for California and the partnerships we will build as the program moves forward.
