The United States Geological Survey (USGS) maintains hydrography datasets for the Nation. The National Hydrography Dataset Plus High Resolution (NHDPlus HR) dataset integrates the High Resolution National Hydrography Dataset, Watershed Boundary Dataset , and 3D Elevation Program digital elevation models. Value-added attributes (VAAs) within the NHDPlus HR dataset provide pre-calculated network characteristics. NHDPlus HR VAA’s provide users with a rich source of data for hydrologic analysis and modeling to help our understanding of how water flows through the network and aid in predicting impacts of events such as flooding and contamination anywhere along the network. VAAs usefulness in the analysis and visualization of network characteristics will be highlighted and demonstrated in this lightning talk.
