摘要
由于空间数据的多尺度性 ,在多尺度的空间数据中也存在概念层次关系。文中根据从小尺度的空间关联规则推导大尺度空间关联规则的思想 ,提出了一种点对象在多尺度的空间数据中生成概念层次关系的算法。实验表明 。
Since spatial data has the feature of multi scale, the spatial concept layer relations also have the feature of multi scale. The paper provides an idea that the small scale spatial association can be gained from the big scale ones by analyzing computing and merging in the perfect multi scale association rules mining system. An idea of gaining the big scale spatial association rules from the small scale spatial association rules is also expressed. The algorithm of judging the similitude between the point objects is offered. From the experiment, it is proved that the algorithm is effective.
