等高线测绘过程中常见技术问题的解决方法

Solution of Common Technical Problems in Contour Surveying and Mapping Process

针对等高线测绘中经常出现的一些技术问题,以南方CASS软件为例对等高线的外业测量到内业绘制方法作了详细介绍,主要包括地貌特征点采集、高程点预处理、绘制地性线、提取高程点数据文件、DTM建立与修改、绘制等高线、等高线后处理工作、等高线的滤波与拟合等内容。

In order to solve some technical problems that often appear in the contour mapping, taking South CASS software for example, this paper introduces the software in detail from contour outside measurement to inside drawing, including geomorphological features point collection, elevation points pretreatment, topographic lines drawing, elevation point data files extraction, DTM creation and modification, contour drawing, contour post - processing, contour filtering and fitting and so on.
