Research of Adaptive Definition Model of Frontier Map Based on Feature Points

Abstract

With increasingly tense social development resources, once involved in territorial issues between the countries, there must be fight for every inch of land. Therefore, it is particularly important to develop a frontier map. This paper combines with the adaptive principle and extraction of feature points to establish an adaptive definition model of frontier map based on the special purpose of the frontier map. And this paper first obtains a scatter diagram of the relationship between the scale limit and negative load by calculating the negative load of the electronic map, and then obtains a curvilinear equation through the differential fitting, so as to find out key feature points to reflect the variation trend of the curve. This paper finally establishes an adaptive definition model of the frontier map, and establishes seven key scales developed by the frontier defining map, so as to make a significant contribution to develop a perfect electronic map of the national boundary.
