3D Hydrography Program (3DHP) 2024 Staged Product (FY25 Release) - ScienceBase-Catalog

This product is new in federal fiscal year 2025 (FY25), and consists only of vector data in a series of feature classes. The product represents the 3DHP dataset and the schema in which it is contained as of September 30, 2024 Future Annual Staged Product releases will reflect the schema at the time the product is generated and include more EDH-sourced data holdings.

Elevation-Derived Hydrography: The USGS’s rich new hydrological features dataset

The US Geological Survey (USGS) is the main source of publicly available elevation data in the United States. One of the USGS’s major programs, the 3D Hydrography Program (3DHP), includes Elevation-Derived Hydrography (EDH), a detailed water features dataset that is derived from elevation data such as Digital Elevation Models (DEMs). EDH fills the need for hydrography data that align with elevation data, which is important for analysis such as flood modeling. It is difficult to use hydrographic and elevation data together if they do not align—for example, a hydrographic features dataset produced from imagery might indicate a different location for a river’s edge than an elevation dataset over the same area. Because EDH data consist of hydrological features derived from an elevation dataset, the two datasets will align, enabling more accurate analysis and hydro modeling. This new dataset promises to be a very useful tool for a wide range of natural resource applications. In fact, the USGS posted a Hydrography Requirements and Benefits Study (Dewberry 2016), which indicated that the value of the benefits provided by hydrographic data could exceed US$1 billion annually in the United States. These benefits are broken down by “business uses,” which include river and stream flow management, water quality, coastal zone management, and many others. Amongst the public and private hydrographic data users who participated in this study, with regards to hydrographic data integration, “the top five requirements for integration with other datasets were elevation, stream flow, wetlands, …

The 3D National Topography Model Call for Action—Part 1. The 3D Hydrography Program

The U.S. Geological Survey is initiating the 3D Hydrography Program (3DHP), the first systematic remapping of the Nation’s surface waters since the original 1:24,000-scale topographic mapping program was active from 1947 to 1992. Building on decades of experience maintaining the National Hydrography Dataset (NHD), the Watershed Boundary Dataset (WBD), and the NHDPlus High Resolution (NHDPlus HR), the 3DHP will completely refresh the Nation’s hydrography data and improve discovery and sharing of water-related data. The design of the 3DHP is based on the results of a study that estimated that the fully implemented program would have the potential to provide more than $1 billion in benefits to Federal, State, Tribal, Territorial, and local governments and to private and nonprofit organizations every year, in addition to myriad societal benefits. The 3DHP would directly support better decision making regarding water resources by providing more accurate, complete, and integrated information than is currently available.The...
