The US Geological Survey has launched the 3D Hydrography Program (3DHP), the first systematic remapping of the Nation’s hydrography since the original 1:24,000-scale mapping program was active between 1947 to 1992. 3DHP data will be based on high-resolution elevation data collected by the 3D Elevation Program collected and validated to meet published specifications, maintained in a streamlined data model, and delivered to users through a series of web feature services and static products. This event explored different components of 3DHP, including a program overview, the data collection approach, data management, and current and anticipated products.
Presenter: Stephen S. Aichele, PhD, with the USGS National Geospatial Program
