Research On The Customized Development Model Of Multi-industry Thematic Application Of High-resolution Remote Sensing Data

Remote sensing thematic system is used for image loading,analyzing,thematic extracting,drawing.At present,there are some problems in the use of remote sensing data for thematic extracting.Firstly,the effective use of remote sensing data becomes a problem as the data gets bigger and bigger.It is difficult to build an integrated model from data sources to remote sensing applications.Secondly,the thematic applications are often developed independently because of the limitations of the industry.Based on the above problems and the present situation of the application of high-level remote sensing data in our country,this paper designs a customized development model suitable for multi-industry thematic application,which is used to develop thematic applications rapidly and utilize high-resolution remote sensing data efficiently.At first,the paper analyzes the characteristics of mass remote sensing data and the current common data organization model.The paper designs the data organization framework for thematic application based on the five-layer fifteen-level image subdivision organization model.The thematic application can get data easily for showing and analyzing in this framework.At the same time,a real-time GIS model is built in this framework to realize the real-time application of data in slicing storage.Then,the paper analyzes the general characteristics of the remote sensing thematic application system and proposes a customized framework for the remote sensing thematic application system.The framework divides the remote sensing thematic application system into components,designs the encapsulation specification of the components and the relationship among the components,and presents the remote sensing thematic application system through XML.According to the specification,the system interface components and nearly one hundred functional components are implemented.The thesis also realizes a custom platform for customization of remote sensing thematic application system.Finally,two pieces of software was customed by the custom platform.It proves the generality and effectiveness of the model.The development model is designed for rapid development of thematic application systems from data storage to thematic applications.The model has great significance to promote the rapid application of mass remote sensing data in the subject extraction and the rapid development of the remote sensing application system in the industry.
