Analysis And Implementation Of3D Campus Geographic Information System

With the development of science and technology, geographic information systemhas made great strides, and the construction of three-dimensional modeling technologyhas made noteworthy achievements. On the basis of the two-dimensional geographicinformation system, through other technical means, to achieve the establishment of thethree-dimensional model, which has played a positive role in the development of a city.The development of3D technology has been created from a simple model developed tomodel application, it has put forward higher requirements on practical application.This Based on the south bank campus of chongqing jiaotong university as theresearch object, the3D modeling theory and technology is introduced into the GISsystem, combining with the current mainstream technology and software, from systemrequirements and feasibility and the key technology of3D GIS system model building,such as platform function design for analysis. In skyline platform, the establishment ofcampus prototype of3D model, using the Visual Studio2010c#campus3D scenesystem for secondary development, implements the south campus of chongqing jiaotonguniversity construction and development of three-dimensional geographic informationsystem. In addition to general2D,2D software commonly used basic map operationfunction, the system also implements the distance measurement area, the terrain profileanalysis and spatial analysis function, let the user be in the system of campus3Dintuitive experience. System will provide data support for the management of schoolleadership department to decide, To improve the three-dimensional city, digital city,digital residential building，it plays an important exemplary significance and role inguiding.
