Design And Implementation Of The Query System For Photogrammetry Standards Based On Web

With the rapid development of photogrammetry and remote sensing, the career of surveying and mapping in our country has been changed from technology of traditional to digital, and now is to informational. With the new technology, many standards had been appeared; it costs much time to use these standards. So, it is exigent request to establish military query system of photogrammetry standard, to improve the nowadays working method. In this thesis, the focus is put on the process of design and implementation of this system, which includes:1. Firstly, the developing background and the meaning of the query system based on Web, as well as the trends of the query system studied both in and out of our country have been discussed.2. The total design and the idiographic realization of the sub-modules have been introduced in detail; include the design of platform, the function modules, the database and the interface. At last, the question of safety has been discussed.3. The question of the identify of the thesaurus has been researched deeply, and the query based on semantic has realized in this system;4. Put forward the matching method of spot symbols based on the structure, solve the question of the matching of spot symbols basically, realize the query of spot symbols on line.5. The function of each modules has been tested, and the function, run process and operation has been introduced with samples.
