3-Dimensional Urban Modeling And The Basic Operational Capability Analyzing

With the urbanization progress of the world soon and strengthening increasingly with the city in the positions, such as politics, economy and military etc., the city is more and more important for the both parties of the battle as the center of the developing region. More and more operations will take place in urban area in the future. The city will become 21 centuries' main battlefield. The research of the urban operation has already become the important topic of the modern war, is also the objective demand that our country supports the national sovereignty and territorial integrity.The analysis of urban basic operation capability is the research of influence characteristic of basic combat-action and the use of weapon and equip in urban area. It is also important part of urban operation theory. Because of can't be satisfying the the request of active combat by using traditional handpile for opration and paper map obviously, it is need to build up stereoscopic urban digital battlefield environment. It's the analysis platform of urban basic operation capability. It can provide the necessary referential information for commanders to draw up the operational plan more reasonable understanding urban battlefield environment completely by analysis.The main contents of this paper have: 3D terrain modeling and 3D groud feature of city, and providing a method for folded building modeling on the basis of topology. The method has the the advantage 2D topology and convenient for spatial analysis. The of the spatial data organization and management, it's used to improve the efficienc of data usage; urban basic operation capability analysis, this is the most important part of the thesis,including influence analysis of smart moving, observing, shooting, concealing, camouflaging, defending, and exploding analysis, road control region analysis etc.. Visualization of 3D-urban for providing intuitionistic detailed urban battlefield environment.
