以彩色数字栅格地图道路数据为处理对象，提出一种基于可变矩形跟踪框技术快速矢量化道路类线要素的方法。在确定道路矢量化规则的基础上，通过采用可变矩形跟踪框技术，结合端点（交点）判断及道路惯性延伸点判断方法实行栅格地图道路的快速矢量化，并克服了当前几种常用矢量化方法的不足。实验结果表明该方法的矢量化效果十分理想。

In this paper , an effective vector algorithm for road from digital color raster map is proposed .On the basis of the road vector rules, we apply adjustable frame tracing algorithm , endpoint ( crossover point ) judgement and inertial direction to road vector on raster map image .This method overcomes the shortcomings of current methods in map vector .Experiment results show that it can vectorize the roads of raster map image rapidly and interactively .
