地理信息系统(GIS)是一种功能强大的分析工具,目前其功能的应用开发仍不充分。本文以美国辛辛那提交通规划研究为例,结合GIS,用计算机动画进行可视化研究。研究交通规划中拥挤程度、CO浓度的三维表现、评估方法。结合ArcView及其3-D分析挂件、AutoCAD和3DSMAX,把传统的用数字、文字描述的评估结果用二维或三维场景、虚拟动画的形式,以友好的用户界面形象地表现出来,以利于专业人士与决策者、市民之间的交流,模拟不同规划方案的实施效果,提供决策的依据。
Geographic Information Systems (GIS) is a powerful analytical tool whose application of functional development is still inadequate. In this paper, Cincinnati traffic planning and research in the United States as an example, combined with GIS, visualization using computer animation. Research traffic congestion in the level of three-dimensional CO concentration performance, assessment methods. Combined with ArcView and its 3-D analysis pendant, AutoCAD and 3DSMAX, the traditional numerical and textual evaluation results are displayed in the form of two-dimensional or three-dimensional scenes and virtual animations with a friendly user interface to facilitate professional People and decision-makers, the exchange between the public, to simulate the implementation of different planning programs to provide the basis for decision-making.
