Shandong Provincial Flood Control And Electronic Sand Table System

This text put forward purpose and meaning of study on 3-Dimension Electronic Terrain for flood control of ShanDong. Reviewed the domestic and international current application situations of relevant technology. Analyzed the inquire to the information management of reducing natural disasters of flood control the systematic current situation. Analyzed inquire to set up one the whole province flood prevention message 3-Dimension words of range manage the system, aimed at the problem in the flood control information management system. Put forward the systematic design plan of study. Utilize the modern high-tech,i.e.Geographical Information System (GIS ) , Remote Sensing (RS ) , Network (Internet), DataBase (DB ), Virtual Reality (VR ), and so on. Uses the different scale the terrain data as well as the flood control works foundation information, Establishes the Shandong Province three dimensional scene, And in three dimensional scene foundation. Thus realizes in the three dimensional scene guards against floods the information management and the inquiry.According to studied theory and the plan in the text, have carried on the experiment site construction. Organic and highly effective integrationed the different criterion spatial data, the flood prevention project data, and to existing system in close integration with, has constructed the provincial level flood prevention information management three dimensional foundation platform. Solved under the magnanimous data environment to guard against floods information fast processing, inquiry, analysis and so on crucial the technology, has completed the entire province 1: 250,000 three dimensional scenes as well as Dawen River basins 1: 10,000 three dimensional scenes constructions, and has connected the flood-control works database, has realized the partial flood-control works information three dimensional inquiry, has realized the hydrodynamic force model in three dimensional system application. Has drawn the conclusion, proposed the later research content and the direction.
