Remote Sensing Applications in Agriculture at the USDA National Agricultural Statistics Service

The United States Department of Agriculture’s (USDA) National Agricultural Statistics Service (NASS) has researched and used remote sensing technology for acreage estimation since the early 1970s. Significant advancements in recent years have enabled NASS to transition the use of remote sensing from primarily a research function to performing an integral role in the agency’s crop acreage estimation program covering all major crops grown in high producing states in the U.S. This accomplishment was achieved in large part as a result of 1) enhanced data partnerships, 2) improved methodologies, 3) increased availability of commercial software, and 4) improved imagery and ancillary data. With acreage estimation now operational, the Agency is focusing its efforts to transition yield estimation from research to operational, as well. Currently corn and soybean yield estimates for 10 major producing states are provided in-season to the Agricultural Statistic Board (ASB) and the NASS field offices. Although, yield estimates are solid, with more experience and research, improvements are expected. Looking to the future, NASS has begun conducting research to quantitatively measure crop progress and condition using remote sensing and intends to expand the use of remote sensing into mapping soil moisture and improving disaster assessments and monitoring.
