Abstract: This paper proposes an algorithm: meta-rule-guided mining multiple-level spatial association rules based on progressive refinement. This algorithm adopts some technologies such as top-down, progressive refinement and meta-rule. Finally, to introduce the application of this algorithm, take it as an example to mining the spatial association relation between the prices of sesame in the products markets and the locations of railways, national highways and rivers.
