重复点要素快速检查与消除方法

提出了一种快速实现土地利用现状图中重复点要素检查与消除的方法。首先将点层划分成若干个覆盖整个区域的一定尺寸的规格格网,对每个规格格网内的点要素采用传统顺序去重的方式进行重点消除。最后在AutoCAD平台上,使用ObjectARX开发工具,实现相应功能算法模型的设计,并验证了这一方法的可行性及有效性。

The Method of Repeated Points Quick Judgment and Elimination

In this paper, a method is proposed to judge and eliminate the repeated points in present land use map quicklily.Firstly di-vided point layer into regular meshes covering the entire area, for points in each regular mesh, eliminated the repeated points by the way of traditional sequence method.Finally, on the platform of AutoCAD, we used the development tool of ObjectARX, realized the algorithm model design, and examples were given to validate the stability and feasibility of this method.
