The Design And Implementation Of Remote Sensing Image Processing Based On ZY-3 Special Products

Due to its irreplaceable features and advantages, remote sensing data has been applied into many areas and also increasingly shifts its focus from military data to civil data. Its image data can benefit many industries. Therefore, remote sensing image embraces another development opportunity. In order to timely,accurately and effectively transfer image data into various thematic products, Satellite Surveying and Mapping Application Center of NASG(National Administration of Surveying, Mapping and Geo-information of China)proposes to design production subcontract of thematic products production software, which is a part of No.3 resource satellite application system. In this thesis, the author is mainly responsible for the design and implementation of the production module and the mapping module of production subcontract of thematic products production software.Production module is the core of the entire thematic products production, including the creation of working space, the preparation of algorithm and data, and the image processing to communicate. Mapping module is mainly to make thematic products, render TIF image, and export JPG image. Thematic map making system consists of three function modules: thematic mapping module, mapping template management module and XML document management module.The major content of this thesis has four parts: 1) using WCF to design and implement thematic products on the basis of full understanding of Remote Sensing Image Processing Based on ZY-3 Special Products.2)combining with the production features of thematic products to design database;3) tuning database memory and evaluating system performance;4)using Arc GIS to make map.
