Point Set Generalization Based on the Kohonen Net

Point set generalization is one of the essential problems in map generalization. On the demands analysis of point set generalization, this paper proposes a method to generalize point sets based on the Kohonen Net model; the standard SOM algorithm has been improved so as to preserve the spatial distribution properties of the original point set. Examples illustrate that this method suits the generalization of point sets.

点集合归纳是在地图归纳的必要问题之一。在点集合归纳的要求分析上，这篇论文建议一个方法基于 Kohonen 网模型概括点集合；标准 SOM 算法被改进了以便保存原来的点集合的空间分发性质。例子说明那这个方法适合点集合的归纳。
