Abstract

Crop production assessments are extremely valuable because of their economic importance in influencing international trade and national economic policies. Associated with the outstanding problems of food supplies in the world, crop production assessments become more and more important. And because of its good time properties and accuracy, remote sensing is becoming an important method of crop production assessments. And models for the forecasting of crop yields using remote sensing satellite data are studied intensively worldwide. After reviewing the experience gained by other researchers in this field, we selected two models, an NDVI-production regression model and a biomass-estimating model, which might be suitable for the estimation of rice and maize production in Korea-north. Satellite data from 1982 to 1997 were utilized within the models to explain the variation of crop production and obtained good results.
