Large scale crop surveys can be made frequently and inex¬pensively during a crop growing season using Landsat data. A crop's at-harvest acreage in a stratum can be estimated from the crop's estimated at-harvest acreage in a small sample of the stratum's segments. The stratum estimate can utilize Landsat imagery obtained during the current crop grow¬ing season and in previous years. A mixed effects analysis of variance model is used to generate a weighted least squares es¬timate of the stratum at-harvest acreage proportion for the cur¬rent year. Similar Landsat based stratum crop proportion esti¬mates can be combined with historical information on non-sampled (or unsuccessfully sampled) strata to provide crop acreage estimates for large regions. These regional estimates of the at-harvest acreage can be determined early in the crop growing season, at different intermediate points, and at har¬vest time |
