摘要
探讨了基于GIS的控制网点自动选取和控制网自动组建方法,提出了一种以数字高程模型DEM为基础,数字地形分析为主要技术手段的控制网自动设计与优化的新方法。通过对测区数字地形分析提取候选控制点,建立关联矩阵,生成控制网,最后用蒙特卡罗方法对生成的控制网进行了精度估计和优化。
On the basis of the study on how to auto-select control points and auto-establish control network with GIS technology,a new method of control network design and optimization is proposed in this paper,which is based on DEM and digital terrain analysis technology.The candidate control points are extracted and control network is established with the help of digital terrain analysis.At last,the Monte Carlo method is used to estiamte precision and optimize the control network.
