| 摘 要： | 为地球资源卫星工程设想的一个应用系统。该系统将包括五个分系统,它们是：·数据接收和记录分系统；·数据预处理和常规产品生产分系统；·应用分析和专家分系统；·数据模拟和评价分系统；·数据分配和用户服务分系统除去常规的卫星接收和预处理系统外,将深入探讨重要的应用分析和专家分系统,这个分系统基本由图像处理、地理信息系统并结合专家知识的应用模型组成。它以预处理分系统的产品(图像数据)作为输入,并利用建立在计算机内人的智能模型,输出若干种类的向量形式的专题图。显然,应用分析和专家分系统不仅比通常图像分析系统有更高的分类精度并考虑在图像解释过程中具有人工智能化。整个应用系统应该是地球资源卫星系统不可分割的重要部份,它能把实时和有效的动态数据提供给各类用户为经济建设服务,同时有可能提供总的统计信息和整个国家或广大地区的专题图。这样的结果对国家宏观规划和决策是非常有用的。这一应用系统将担负检验并决定地球资源卫星任务的最后有效性。

| Abstract: | An application system is proposed for the Earth Resourue Satellite(ERS) project. The system under consideration consists of five subsystems, as follows: .the data receiving and recording subsystem; . the data preprocessing and production subsystem; .the applied analysis Modeling and expert subsystem (AAS) ; .the data simulation and evaluation subsystem; .the data distribution and user's service subsystem. Except the tradionally satellite receiving and preprocessing subsystem, the. important subsysten of AASwill be discussed further in detail. It is basically a geographic information system (GIS) but incorporating with human intelligence of interpretation of remote sensing imagery. Such a subsystem takes the products (image data) of preprocessing. subsystem as input and produces different thematic map in vector format by using the human brain knowledges assisted by computer.Obviously, the advantages of AASare not only the higher accuracy of classification than the common image analysis system or GISbut the capability of human intelligence in the process of image interpretation. The whole application system is an unseparable important part of Earth Resource Satellite programme requirements. It will provide the real time and effective dynamic data information to various users for different economic constructions, and will be able to supply the global static information and thematic map of a certain part of the country or even the whole country also. These results are very useful for national planning and macroscope decision making. The application system will undertake the task to check the final effectiveness of the Earth Resource Satellite project. |
