Improving State Hydrography in Tennessee with 3DHP

The State of Tennessee is embarking on a journey to improve its statewide hydrography dataset through participation in the USGS 3D Hydrography Program. They have funded a HUC 10 pilot project in east TN in an attempt to help identify funding partners and develop sample data that can be shared and highlight the value of 3DHP data. The presentation will also identify some use cases in two state agencies (Transportation and Environment and Conservation) that helped move this effort forward and begin development of a broader 3DHP project proposal for FY24 and respond to future USGS Broad Agency Announcements.
