3DNTM Development Tracks

Topography is defined by elevation and hydrography; elevation shapes hydrography, and hydrography shapes elevation. To support a braod range of applications, the 3D National Topography Model integrates USGS elevation and hydrography datasets to model the Nation's topography in 3D.

Track 1: Complete nationwide elevation and hydrography baseline datasets

• Delivers the terrestrial component of the 3D Nation vision of continuous data surface from the depths of the oceans to the peaks of the mountains

Track 2: Pilot integration of hydrography and elevation

• Provides universal discovery and sharing of water information as the geospatial foundation for the Internet of Water
• Provides foundational data to critical initiatives including 
  • FEMA Risk Rating 2.0
  • The National Water Model
  • Aquatic Resources mapping for the Clean Water Act
  • National Landslides Prepardness Act

Track 3: Design and implement next generation of integrated data

• Underpins a broad range of applications including flood risk management, hazards response and mitigation, infrastructure management, climate change science, and more.

Track 4: Research and develop 3D data model

• Enables new and emerging applications
  • Multiple vintages enable change detection
  • Water-related applications move from the neighborhood to the street-level in accuracy
