浅谈地形图上切绘勘探剖面线

TO DRAFT EXPLORING SECTION LINE BY MEANS CUT DIRECTLY ON THE TOPOGRAPHICAL MAP

主要介绍在地形图上切绘勘探剖面线的制作技术和方法，与传统的野外实测方法相比，除精度符合规范要求及质量可靠外，还具有节省开支、降低消耗、减轻劳动强度、提高工作效率的优点。

In this paper, the author has mainly introduced the technique and method to draft exploring section line by means of method cut directly on the topographical map. Comparing with the conventional field survey method,this method,besides the precision accorded with specification requirement and the quality is reliable, has also following advantages: cutting down the expenses and the consumption of raw materials,reducing the labour intensity and raising the working efficiency.
