介绍了一种在不规则三角网上进行地形特征点生成的方法，可以自动实现地形特征分析、特征信息提取、地形正负向趋势判断、以及地形细节精细化等，较好地解决了用等高线做数据源构建不规则三角网时出现的地形细节信息不足以及地形细节信息丢失等问题，可以广泛应用于DEM 数据更新精化、水文分析、地学分析等领域。

This paper provides a method to extract terrain feature points based on a triangulated irregular network, which can automatically conduct terrain analysis, terrain feature extraction, determination of terrain positive and negative trends, the water relationship coordination, water elevation calculations and terrain details optimization. The method solves the problem of accuracy lack and loss of terrain detail in the process of creating irregular triangular when using the contour as data source. The method could be widely used in the DEM data refinement optimization, hydrologic and geo-science analysis.
