An Error-Components Model for Prediction of County Crop Areas Using Survey and Satellite Data
利用调查与卫星数据预测县级作物面积的误差分量模型
Knowledge of the area under different crops is important to the U.S. Department of Agriculture. Sample surveys have been designed to estimate crop areas for large regions, such as crop-reporting districts, individual states, and the United States as a whole. Predicting crop areas for small areas such as counties has generally not been attempted, due to a lack of available data from farm surveys for these areas. The use of satellite data in association with farm-level survey…
