地图集编制中,主要数据均要求为矢量格式,栅格图矢量化是数据处理的一项重要工作,针对一般方法在彩色栅格图矢量化方面的不足,以Corel PowerTRACE X5为例对几类栅格图进行试验和应用,并对结果作分析,在交互控制自动矢量化过程中,当设置100%的精度时,彩色图矢量化精度达98%以上,黑白线画图接近零误差,矢量化取得了满意的结果。

In the compilation of atlas, the main data are required to be of vector format, and grid map vectorization is an important work in dam processing. Aimed at overcoming the shortcomings of the common method in colored grid image vectorization, this paper applies and tests Corel PowerTRACE X5 on several types of grid image and analyzes the results. The result of vectorization is satisfac- tory for the reason that the accuracy of colored image vectorization is 98% and error of black and white line graph is close to zero when the accuracy is set to 100% in the process of interactive control automatic vectorization.
