CTIC has partnered with Applied GeoSolutions and The Nature Conservancy on the development, testing and application of the Operational Tillage Information System (OpTIS), an automated system to map tillage, residue cover, winter cover, and soil health practices using remote sensing data. While OpTIS calculations are performed at the farm-field scale using publicly available data, the privacy of individual producers is fully protected by reporting only spatially-aggregated results at regional and watershed scales. OpTIS-based data are currently available for the years 2005 through 2018 for the US Corn Belt, including all of Illinois, Indiana, and Iowa, as well as parts of: Kansas, Michigan, Minnesota, Missouri, Nebraska, Ohio, Oklahoma, South Dakota, and Wisconsin.
The Operational Tillage Information System (OpTIS) has been developed by Applied GeoSolutions (AGS) and the Conservation Technology Information Center (CTIC) as a method for the automated use of remote sensing (satellite-based) data to monitor conservation practices in agricultural systems, including various forms of reduced tillage and the planting of winter cover crops. While the OpTIS calculations are performed and validated at the farm-field scale, the privacy of individual producers is fully protected by distributing only spatially-aggregated results – at the county and watershed (8-digit HUC) scale.
