Research And Implement Of The Remote Sensing Image Database System In The Soil And Water Conservation Based On ArcSDE

As the Remote sensing (RS) technology developing rapidly, it is widely used in planning, management, supervision, and other application in soil and water conservation. In the soil and water conservation information system, RS technology, for its characteristic of extensive coverage, high speed and being objective, receives more attention in, also becomes an important way to monitor soil erosion.The research status of soil and water conservation information system and the application status of RS technology in soil and water conservation were studied, which showed the important role that the RS image database system played in the information system. In the thesis, ORDBMS was chosen as the structure of the RS image database system after the existent database structures were studied. Compared with the RS image storage in Oracle 9i, the method of storing the RS image based on ArcSDE was selected to design the RS image database system. According to the feature of the RS image database system in the soil and water conservation information system, the rule of tiling and the way to build pyramid model were discussed through experiments.The RS image database system should satisfy the business demand in the soil and water conservation on conveniently storing and managing large amount of the RS image. The function and the database structure of the RS image database system were designed to meet the need of the system. In the end, based on the application tools-ArcObjects and Visual C++, all designed function of the system was realized using the system integration and data interface technology. Thus, the RS image database system was built to manage the RS image in the soil and water conservation.
