Update on Spatial and GIO Related Issues

This update focuses on integrating key Spatial Water Datasets such as the National Elevation Dataset (NED) and National Hydrography Dataset (NHD). Important stages, partnerships, tools, and standards are highlighted along with the coordination efforts for spatial data. The collaboration between various agencies like NWS, NRCS, USFS, and USEPA is discussed, emphasizing the advancement of high-resolution data sets for water projects. This comprehensive framework aims at streamlining data processes and enhancing geospatial insights for coastal watersheds and state partners.
