摘要
等高线是地形图的重要元素,本文详细介绍等高线的特征,以及测绘地形图等高线的过程和方法。通过对航空摄影测量中几种测绘等高线的方法进行比较,总结出利用全数字摄影测量系统配合其他软件测绘等高线的方法不但精度高,而且实用快捷。
Contour is an important element of the topographic map. This paper detailedly introduced the character of the contour, and the process and method of mapping contour of topographic map. Compared with several methods of mapping contours in aerial photogrammetry, it summarized that the method of full digital photogrammetric system work with the support of other software is not only with high precision but also simply used.
