A Landsat Agricultural Monitoring Program (LAMP) was established to monitor Iowa's corn crop in near real-time. The Program utilized Landsat data in conjunction with collateral data sources to monitor crop development and identify/assess anomalies and crop stress. Throughout the growing season, data were screened manually and by computer for indications of crop condition. Alarms were generated by weather related events and/or by changes in the satellite imagery. These alarms were then assessed as to their nature, extent, severity and projected impact on crop production. Landsat digital data, coupled with specially gathered collateral data, were used to update this initial alarm impact assessment. During the 1976 growing season, LAMP identified and assessed the effects of heavy rains, hail, tornadoes and drought on corn production in Iowa.
