摘要
本文分析比较了目前城市大比例尺数字化测图中主要方法的优缺点,并为实现数字化地形图中不连续线、面状符号及复杂线状符号向GIS的自动化导入,针对电子平板法提出了基础线的概念。对全站仪草图法,提出在全站仪上加挂微型计算机,并用常规摄像方法代替草图。
This paper analyze the advantages and shortcoming of the two main methods of present digital mapping, the technique of electronics plate and total station with sketch map. For the auto-enter of discontinous lines, polygon symbols and complex linear symbols in digital terain map in to GIS, the concept of base-line was put forward refering to . As to the technique of electronics plate, that the total stationer integrated with a mini-computer and that a CCD instead of draft are suggested.
