Abstract:

High-resolution remote sensing data has become a major source of information for natural resources monitoring, disaster assessment and ecological environmental protection and so on with the implementation of the major high-resolution earth observation system project. But the standard specification of remote sensing application is always a weak link in the development of remote sensing industrialization. On the basis of the research and analysis of the development status of standards for remote sensing applications at home and abroad, requirements for common standards for the applications system of China high-resolution earth observation system were analyzed from the actual needs of the remote sensing application business of various related industries in our country for the standard specifications. Adopting the unified modeling tool (UML) and object-oriented software analysis and design method, from the information perspective and the computing perspective, the general technical specification system framework for the applications system of China high-resolution earth observation system is proposed, including three kinds of levels including basic standards level, professional application standards level and subject application standards level, involving 7 categories of general classes, data classes, data products, application services, management, professional application and subject application, totally consisting of 42 sub categories. According to the common technical specification system framework of the application system, the research puts forward specific standards and specifications that need to be studied and formulated under each class. Among them, the basic standard is the focus of this research, and the basic standard involves 5 categories, 24 sub categories. In view of the basic standards, 48 specific technical specifications that need to be studied are put forward. In the future, the common application technical specification system of high resolution earth observation system in China will be continuously developed and perfected with the progress of the project and the formulation, implementation and test of the standard.
