自1960年代开始实施美国航天局的遥感研究方案以来，其主要目标之一就是提高卫星获取的多光谱数据的机器处理技术水平。可能已经研究了关于使用这些数据来确定类型，监测条件，并估计个体发育阶段的文化植被。本文综述了国外作物遥感估产技术的发展现状。注意的是陆地卫星数据采集，登记和预处理方面的问题，数据转换，数据建模，比例估计，标签，发展阶段模型，作物条件模型，并展望未来的发展。
Since NASA's program of research concerning remote sensing was initiated in the 1960s, one of its major objectives has been to advance the state-of-the-art in machine processing of satellite acquired multispectral data. Possibilities have been studied regarding a use of these data to identify type, to monitor condition, and to estimate the ontogenetic stage of cultural vegetation. The present investigation provides a review of the state-of-the-art of the technology used to make remote sensing crop production estimates in foreign regions. Attention is given to Landsat data acquisition, aspects of registration and preprocessing, questions of data transformation, data modeling, proportion estimation, labeling, development stage models, crop condition models, and an outlook regarding future developments.
