Application Of 3D Space In Planning

Since reform and opening-up, the economy of our country gets the development at full speed, the construction projects of all parts are launched in an all-round way too, have made constant progress in the educational circles too in research of planning the field. GIS analyses and processes tools as a kind of advanced computer, the application planning the field is paid attention to day by day too, this text researches and analyses the application that GIS is planning the field in terms of 3Dal space. It is to popularize routine GIS 2D data model 3D space that the application in the field of GIS of 3D technology, realize space in model it analyses to be and visual to model , facilitate user ocular analysis expresses the means, it is a research focus in the field of GIS. The main target in planning is used is the building and topography . As to building, in what people pay close attention to the thing being whole structure and each other, or and spatial relationship between the environment of it. Comparatively speaking, a more one how can get analysis of geographical environment appraise the data and standard in3D space as to landscaping, and can carry on the vision analysis with visual 3D to the existing model through the low-priced means . Important component that this text " protects and supervises the information system in the scenic spot "of "10th 5 Years Subjects "of the key research projectas the country, carry out the studying appliedly of essential , foundation on the policy of " strict protection , unified management , reasonable development , continuous utilization " of scenic spot in the country. Here originally in the article, have carried on research to 3D space analysis and two visual parts of 3D space separately. Analyse the respect in 3D, on the basis of investigation and research and mathematics model are analysed after carrying on a large amount of on the spotting, have proposed the evaluation criterion system to the view of the style and features of view of Gorge-River; And many kinds of information technologies taking GIS as the core have realized the appraisal on Laser Three Gorge on DANinghe River barranca view of Wushan (the pilot project of the subject ) as the means, and has received the good result. The visual respect of the 3D is to the need of planning , it is combined with data form of GIS in OK that study, operate the visual model of the 3D by way of according with and planning to be used to. Through using OpenGL technology , study how to click by according with the way in which the human eye is observed and used to and carrying on the 3D to the topography visually even more in the definite geographical coordinate, the ones that adopted are being penetrated and perspecting the errors shown to the topographical 3D brought while avoiding usually in GIS software visually.
