| 摘 要： | 等高线注记是一种特殊的曲线注记,它除了有普通曲线具有的分段注记以及在曲线光滑部分注记等问题外,还存在字头朝向问题和沿辅助曲线注记的问题。本文提出了新的分段注记算法以及高程朝向判断方法,使等高线注记有更好的注记效果。

| Abstract: | Label on contour curve is a special label.In addition to the general segmentation label of the curve and labeling on some issues such as the smooth curves,there are still some problems including character head direction and issues of labeling along the auxiliary curves.The paper presented a subparagraph labeling algorithms as well as elevation towards the judgment on elevation orientation for better effects of labeling on contour,that label on contour better effects. |

| Keywords: | anti-Douglas character head direction edge development labeling along the auxiliary curves |
