基于WebGIS的數(shù)字校園設(shè)計與實現(xiàn)
[Abstract]:With the development of human society and the acceleration of urbanization in China, the construction of digital city is imperative. The operation of campus can not be separated from learning, life, teaching and research, management and other aspects, flexible and efficient campus system can coordinate the operational efficiency of various departments on campus, and provide a good basis for the work and life of teachers and students on campus. Therefore, based on the existing information resources of the campus of Chongqing Jiaotong University, we need to build a three-dimensional digital campus system to realize the spatial information display, search, analysis, books, classroom, business information management and other functions of the digital campus system. This paper takes the south bank campus of Chongqing Jiaotong University as the research object, takes the GIS data as the modeling foundation, first uses the City Engine three-dimensional modeling software to make the three-dimensional model of various buildings quickly; Then the 3D scene is published to the ArcGIS Server geospatial server, and the system environment is built by using the technology of B / S, using the JAVAEE SSM development framework and MySQL open source database, using ArcGIS Server for JavaScript as the GIS client development platform, and using the TomCat open source application server. Realization and verification of map function, actual campus, e-commerce platform, book management, classroom management and other modules. Finally, the realization of Chongqing Jiaotong University digital campus system platform. The main work of this paper is as follows: (1) collecting and processing campus geospatial data, analyzing the technical platform needed for the development of 3D digital campus, understanding its working principle, To provide the data basis and development platform technical support for the 3D digital campus development. (2) compare and analyze each modeling software first, then use CGA code based on City Engine 3D modeling software, to the buildings, roads, These three aspects of the rapid modeling, the necessary dynamic parameters of the model adjustment, the final rapid batch generation of three-dimensional scene; (3) comprehensive analysis of the three-dimensional digital campus system and the functions of each subsystem, Complete the overall design of the system architecture and database design, achieve map function, classroom management function, library management function, e-commerce, (4) publish the 3D scene to the geospatial server, realize the development of the client and server functions based on the open source development framework and technology, and then verify the function modules of the system. Finally, a three-dimensional digital campus system based on WebGIS is implemented.
