Study & Development Of Geodesic Database System Of Shandong Province

The author introduces to you the main contents and research process of Shandong geodetic survey database in this paper. From the achievement management and application of surveying and mapping, the author expatiates on the purpose and significance of Shandong geodetic survey database's establishment. In addition, the author discourses upon the essential steps for building Shandong geodetic survey database system in this paper.To data management, this paper mostly discusses data manipulation and input of trig point result and bench mark result. The following is some basic portions of trig point result:First-order and second-order triangulation are overall adjusted in national astro-geodetic network. The product manipulation of its have been finished by national surveying and mapping bureau and its product could be inputted into database directly. Third-order and forth-order triangulation need to be adjusted in advance and then could be inputted into database by rules. Military point control has been manipulated by our company and could be put into database directly. Bench mark includes following portion: National first-order and second-order level net adjustment has been finished by national surveying and mapping bureau and its product could be inputted into database directly. Other orders bench mark of Shandong province need to be adjusted and then could be inputted into database by rules. In chapter two and chapter three of this paper, much adjustment method and process of third-order and forth-order triangulation and bench mark of Shandong province are discussed.The construction goal, function design, system performance, system characteristic, and important problem exploitation are discussed in database design segment. A whole evaluation of database is given. Finally, All function and use specification of triangulation subsystem and leveling subsystem in geodetic survey database system is given in using segment.
