摘要
地形图中的注记内容转为GIS属性数据是GIS属性数据生产的一种快捷有效的方式。本文基于EPS脚本技术,介绍了一种道路注记到道路属性的转换方法,重点解决了道路注记的预处理和道路注记与道路中心线的匹配问题,并通过VBScript语言实现了该方法。通过实验论证,该方法的正确率能够达到95%以上。
The conversion from annotations to attributes is a effectual method for data security in survey data sharing and distributing. This paper introduces a method of converting from road annotation to attribute based on EPS scripting technique, focuses on solving road annotation of pretreatment and road with annotation on the road center line matching problem, and then implements the method through VBScript Language. At last, it proves by experiments that the method of correct rate can reach more than 95%.
