USGS research cooperative agreement for land-cover accuracy assessment and area estimation

**Buyer:** Geological Survey (U.S. Geological Survey)
**Posted:** November 02, 2026
**Respond By:** December 03, 2026
**Identifier:** G27AS00040
**NAICS:** 541360, 541720

The U.S. Geological Survey seeks a research partner to improve how annual remote-sensing land-cover products are assessed and used to estimate land-cover area.
- **Government buyer:** U.S. Department of the Interior, U.S. Geological Survey (USGS), through the Earth Resources Observation and Science (EROS) Center and National Land Imaging Program.
- **Opportunity:** One cooperative agreement for an eligible participating partner of the Great Lakes Northern Forest Cooperative Ecosystem Studies Unit (CESU); USGS will collaborate substantially in the work.
- **Research requested:** Improve sampling and statistical strategies for accuracy assessment and area estimation for annual land-cover monitoring, including Annual National Land Cover Database (NLCD) products.
  - Investigate sampling restratification and sample reallocation, and develop stratification approaches that address multiple accuracy metrics.
  - Quantify and incorporate interpreter variability and reference-data uncertainty.
  - Develop and implement sampling-design and analysis protocols for accuracy assessment in Alaska and Hawaii.
  - Share findings through presentations, journal publications, and communications with partner federal agencies.
- **Funding and performance:** Estimated total funding is $135,000, including approximately $45,000 for the first budget year. The anticipated project period is three years: one base year and two additional budget years, with later funding dependent on satisfactory progress and availability of funds. No cost sharing is required.
- **OEMs and vendors:** No OEMs, commercial vendors, or product part numbers are identified.

### Description

The U.S. Geological Survey is offering a cooperative agreement to an eligible participating partner of the Great Lakes Northern Forrest Cooperative Ecosystem Studies Unit. The project will research and implement sampling and statistical strategies to improve accuracy assessment and area estimation for annual remote-sensing-based land-cover monitoring, including examining impacts of reference data uncertainties. The work supports assessment of USGS land-cover change products such as the Annual National Land Cover Database. The notice anticipates one award with an estimated total funding of $135,000.
