Quantitative evaluation of computer-processed ERTS MSS data classifications has shown that major crop species (corn and soybeans) can be accurately identified. Preliminary comparisons of acreage estimates from ERTS data and ground-based systems agreed well. The classifications of satellite data over a 2000 square mile area not only covered more than 100 times the area previously covered using aircraft, but also yielded improved results through the use of temporal and spatial data in addition to the spectral information. Furthermore, training sets could be extended over far larger areas than possible with aircraft scanner data. The results demonstrate the potential utility of this technology for obtaining crop production information.
