摘　　要：针对传统水深综合原则适用性不强、可操作性差等缺陷,利用海底地形骨架线作为反映区域趋势的趋势线。构网过程中,通过约束角度和距离控制网络结点的生成,实现水深网的自动构建。实验证明,该方法可以很好地控制水深分布密度和结构,反映出的海底地形趋势比传统菱形网更加合理,为水深自动综合提供了一个新思路,具有一定的可行性和实用价值。Aim at the traditional sounding generalization principle's shortcomings,which are applicability is not strong and operational difference,we used seabed terrain skeleton line as a trend of regional trend line in this paper.In the process of triangulation,with generating the constraints of angle and distance control network nodes,we realized the automated construction of the sounding network.Experimental results show that this method can well control distribution density and structure of the sounding,and reflect the trend of submarine topography more reasonable than traditional diamond mesh.This method will provide a new way of thinking for sounding automatic generalization,and have certain feasibility and practical value.
