| 摘 要： | 道路模型是城市地理信息系统的基础,在系统设计中既要考虑数据的组织和存储方式,又要顾及到其视觉效果.以交警地理信息系统为背景,以对路网要素标识的惟一性和道路模型的视觉效果为切入点,提出了一个多层复合道路模型.该模型通过运用基于地理位置的编码规则对路网要素的编码确保了对路网要素的惟一标识,通过引入参数化的道沿过渡线和绘制路面标线的方法提高了道路模型的视觉效果.实践证明,该道路模型能够较好地满足交通管理系统的应用需求.

| Abstract: | Road model is foundation of city's geographical information system(GIS),should consider organization and memory way of road's information data in system design,and also take into account to its visual effect.The traffic police's GIS is taken as the back-ground;the authors take the uniqueness identification of the road network elements and visual effects of the road model as breakthrough points,provide a multilayer compound road model.This model has guaranteed uniqueness identification of road network elements through coded them by a coding rule based on geographical position,through introducing the line of road boundary with parameters and drew road traffic marking raise the visual effect of the road model.Practice has proved,this road model meet the application demand for the administrative system of traffic well. |
