Design and Realization of Red-Line Layout Based on GIS
-
摘要: 规划道路红线是规划、布局整个城市的基本骨架, 是规划部门非常重要的数据信息.但目前规划道路红线还停留在传统手工设计和管理上, 已经跟不上城市的快速发展.只有将规划道路数字化, 才能解决这种矛盾.分析了规划道路红线在城市规划行业中的重要性, 以及GIS技术在规划道路红线中的地位, 并针对规划道路红线的特点, 设计出规划道路红线地理信息数据并对红线的录入操作, 比如说道路中线、边线、拐角处理, 交叉口处理, 以及喇叭口处理都做了详细的介绍, 旨在能够利用计算机技术和GIS技术实现规划道路红线的数字化, 以满足城市规划领域的需求Abstract: Road red line layout is the framework of layout of the whole city, and thus is very important data for the urban planing department. But the traditional design of road red line layout cannot keep up with the development of the modern cities. This problem will not be resolved unless red line layout is digitalized. Hence, the authors of this article analyse the importance of layouting road red lines in city planning, and the status of GIS technology in the layouting. According to the characteristics of the road red line layout, the authors design digital data and details the function of inputting and creating red line data, such as road mid line, edge line, curves, intersect and trumpet with an aim to make use of computer and GIS technology to realize digital data of layouting road red lines, and to satisfy the demand of the practical city planning.
