| Abstract: | The paper addresses the problem of using LANDSAT data to obtain estimates of crop areas at the county level. In the paper, LANDSAT data are used to supplement ground data collected in a nationwide agricultural survey. The paper extends the Battese-Fuller estimation model to a stratified sample design. The resulting estimator is evaluated on a six county area in South Dakota |
