【摘要】 以区域性主要农作物种类识别、长势分析与产量估算及农业种植结构现状监测为主要研究对象,开展适于农业管理部门业务化运行的卫星遥感信息处理的关键技术研究。从分析主要作物类型识别的遥感物理依据入手,提出了卫星遥感数据处理及专题信息提取的基本技术框架、主要农作物类型及种植面积信息的提取方法以及主要粮食作物长势分析和产量估算模型,并对结果进行了简要的精度分析。更多还原

【Abstract】 Focusing on agricultural crop monitoring, the authors have presented in this paper the key technology for satellite remote sensing information processing, which is expected to be operational. Starting with an analysis of the physical basis of remote sensing for crop type identification, this paper has not only given a technical framework for satellite remote sensing data processing but also presented the approaches to the thematic information extraction from remotely sensed data. In addition, A model for estimation of winter wheat yield has been formulated, with a description of the means for accuracy assessment.更多还原
