The digital city planning information system realizes the digital weifang as an example
The history! Xiang, hong-li sun, Kong Fan wei (shandong university of science and technology, shandong Qingdao! 266510) abstract: the construction of digital city needs to solve some key technical problems, such as massive spatial data management technology, large-scale 3 d scene visualization technology, based on 3 d data analysis and computing core technologies. To this end, the article to the Sky Lin e company T erra Su ite series of software products T erraExp lo rer P ro were as make and modeling the three-dimensional geographic information platform, the integrated use of 3 d model building technology, build digital weifang three-dimensional urban planning information system. Key words: digital city; 3 d G IS; Virtual reality; Urban planning central map classification number: P208! ! ! Document identification code: B! ! ! Article number: 1001-358x (2008) 02-0055-04: data preprocessing, three-dimensional data integration and system work can be applied. Its system framework is shown in flow diagram 1.
1! As a whole, the system architecture process is based on the digital weifang three-dimensional geographic information system

2! The system data production process is viewed from the process of data and the three-dimensional geographic information system of weifang
The system mainly includes preliminary
