The management and quality analysis of the primitive images have been analyzed and studied in this paper, of which the content and structure are as follows:Firstly, the developing background and the meaning of the management and quality analysis of the primitive image, as well as the trends of the management and data quality of the image database studied both in and out of our country, have been discussed in detail.Secondly, the developing direction of the technology of the remote sensing image and the importance of the remote sensing images in the field of economy nowadays have been analyzed systematically. And it is pointed that the primitive image with the elements of interior and exterior orientation will become more and more important as a sort of image production.Thirdly, the hierarchical structure of database, especially the SQL Server adopted in this system, has been deep studied and analyzed in the aspects of Applying Program Interface, Internet Data Connector and ActiveX Data Object.Fourthly, the methods of assessing the quality of the remote sensing image have been put forward in the terms of geometry, construction and the integrality of the assistant information.Fifthly, the model of propagation of errors of the precision of the ground coordinates has been calculated in the steps of inner orientation, spatial resection and answering based on the deep analysis of the principles and processes of inner direction and space resection, which have also been experimented and analyzed in term of numerical value.Finally, the total design and the idiographic realization of the sub-modules have been introduced in detail, based on which the design and development of this system are realized in combination with the program languages such as VB6.0, VC6.0 and SQL.
