Research on Multi-scale Spatial Association Rule Mining of Point Object
Chen Jiang · 2004
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.
