Research And Realization In Geographic Information Spatial Decision Support System

The project is developing the Geological spatial information decision support system by using MapX component technology on the basis of researching space technology to support decision-making.As the development of technology and application,the present DSS has not already adapted to the requirement which various industries solve the complicated problem. SDSS, the tendency of GIS and DSS integrity is now emphasized more and more worldly. However, at present, there are still many different understandings on the system. At the same time, there is not much the practical application in making decision of water circumstances. For the current situation ,the paper researches the questions: discussing the SDSS formation and development, the important function of scientific computing visualization in the development of man-machine interactive contact surface,deeply analyzing scientific computing visible technology, simultaneously ,discussing the overall structure based on visible man-machine interactive system and the organization pattern of spatial and attribute data, giving the logical design and the physical design structure, and then proposing the overall structure in the space database management system, and discussing the spatial data and the attribute data connection. Benxi LiaoNing is as the experimental unit, builds the main function interface of making-decision supporting system and realizes the management in water circumstance.At present, because of working load bigger, this system has only completed the Benxi water circumstance policy-making support and the management, the applicable scope on the other hand is also narrow, and the following research will be further expand and make it based on the foundation ,in order to make the research results obtain a bigger promotion and the application.
