The University of Wyoming, through its Wyoming Geographic Information Science Center (WyGISC), is leading a pilot project funded by the U.S. Geological Survey (USGS) National Geospatial Program under CFDA 15.817 (National Geospatial Program: Building The National Map). Awarded on September 30, 2025, with $299,425 in federal funding obligated through August 31, 2028, the project will assess the workflow and workload requirements for 3D Hydrography Processing (3DHP) across Wyoming using the Snake River Headwaters HUC8 watershed (17040101) as a pilot study area covering 1,711 square miles. In partnership with Woolpert, Inc., a designated USGS Geospatial Product and Services Contractor, WyGISC will produce elevation-derived hydrography data products and document the processes, skills, and resources necessary to expand this work statewide.

The resulting 3DHP hydrography products will directly benefit local, state, and federal entities within the pilot watershed, including the Town of Jackson, Teton County, the Teton County Conservation District, USDA Natural Resource Conservation Service, USDA Forest Service, and Grand Teton National Park. WyGISC will leverage these products and findings to educate and raise awareness among other Wyoming stakeholders regarding the value and applications of 3DHP data products, positioning the state for future investment in completing this work across all of Wyoming. The project is supported by matching funds allocated by the Wyoming State Legislature, reflecting the state's commitment to developing this critical geospatial infrastructure for flood risk management, natural hazard mitigation, and resource planning.

Wyoming 3DHP pilot project - upper snake river watershedperiod of performance: 09 30 2025 - 08 31 2028ABSTRACT summary: the wyoming 3DHP pilot project is a one-year initiative aimed at assessing the workflow and associated workload for completing 3DHP processing for the entire state of wyoming. The pilot project study area is the snake river headwaters HUC8 watershed (17040101), with an area of 1,711 square miles. The project will be led by the wyoming geographic information science center (WYGISC) at the university of wyoming, working in partnership with woolpert, INC., a designated USGS gpsc contractor. The purpose of the project and our public-private partnership approach is to gain the necessary skills, knowledge and understanding to champion and pursue future wyoming collaborators to further invest in completing this work for the entire state. Intended beneficiaries the resulting 3DHP hydrography products will benefit local city, county, state and federal entities based in the pilot watershed (town of jackson, teton county, teton county conservation district, US department of agriculture natural resource conservation service and forest service, and US department of interior grand teton national park). WYGISC will further utilize the final products to raise awareness and educate other local, state and federal partners on the value of the 3DHP data products and their potential uses. The federal-state cooperative agreement is being supported with matching funds allocated by the wyoming state legislature.
