Research And Application On Precision LUCC Monitoring System Based On 3S Technology

3S technology in the land, resources, environment, industry gradually attention and space exploration, database building and supporting decision-making by developing in depth, but in land use / cover change (Land Use / Cover Change) there are still inadequate monitoring. The main problems: the database for a long time, low efficiency, often using artificial data than the right, often to monitor the accuracy of less than a point of order request. Therefore, the paper quoted neighborhood merging of the algorithm thinking, comprehensive application of 3 S technology to Visual Basic 6.0 for the integrated development platform to ARCGIS8.3 the second development tool kits in ArcObject components and database development components and DBGRID DATA ENVIRONMENT The integration of the development of remote monitoring systems.The work done by the paper as follows:1. The analysis of the current land-use management tools, comprehensive application of technology 3 S establishment of a monitoring system for remote sensing image of the importance of doing a demonstration.2. Focused on the remote monitoring system model structure, function and module theory, analysis of the database structure and data relationships.3. A neighborhood on the merger method of thinking, algorithm design process and the preparation of the core functions of the code.4. In application of remote sensing monitoring system, the technical design of the specific routes, using mathematical methods of field data error checking, and eventually realize the study area overall land use planning, land acquisition and illegal land use in monitoring the construction.The results prove that the use of neighborhood algorithm thinking of the merger plans grouper comparison of remote sensing images monitoring system for simple, efficient access, monitoring accuracy of the state regulatory requirements.
