NRI imagery should not be confused with the NAPP and NAIP imagery used to produce Missouri's first and second generation DOQQ's and FSA compliance products. Neither meets NRI resolution requirements for collecting selected NRI data elements and aiding field office data collection.
Aerial photography covering Missouri's sample segments is flown in late May, June and July.
Additional coverage is sometimes acquired for the Wetland Reserve Program (WRP) sites and other special applications. NRI utilizes high resolution, 9x9 color film. Each photo is segment centered with GPS and acquired at a contact scale of 1:7,920 (1 inch = 660 feet) with a resolution of 0.15 meters.
