Research of Land Frontier Demarcation Technology Based on the Feature Matching

Abstract

Nowadays, many countries still have border territorial disputes, and there is a must to fight for every inch of land in case of involving in the territorial sovereignty, so there is a need of exact demarcation method. On this basis, this paper researches the land frontier demarcation technology. This paper first combines the slope shape combination principle with plan curvature based on the feature matching principle to construct a model for the plan curvature and slope shape combination method, thus obtaining a ridge line and a valley line, and then obtaining the ridge line after refinement through its refinement process. This paper finally extracts and obtains an ultimate frontier demarcation line (ridge line) by the ESRI secondary development components of the computer technology. In addition, through comparison with the physical simulation method of running water, the model method constructed in this paper is significantly superior to the physical simulation method of running water.
