MINING CO-LOCATION PATTERNS FROM SPATIAL DATA USING RULEBASED APPROACH

[摘要] Co-location pattern is a group of spatial features/events that are frequently co-located in the same region. The co-location pattern discovery process finds the subsets of features frequently located together. Co-location rules are identified by spatial statistics or data mining techniques. A co-location algorithm has been used to discover the co-location patterns which possess an ant monotone property. This algorithm includes a pruning technique to make the item set to get only the most interesting patterns.
