Spatial Association Rule Mining Based on Overlay Analysis and Area Calculation

A spatial association rule mining method is proposed in this study,including support counting method based on overlay analysis and area calculation,and corresponding mining algorithms.Using this method,the extraction of spatial transactions is not needed,and association rules can be mined out directly from layers of polygon features.Besides,the results are easy to be visualized with the help of GIS.An experiment with real-world data shows that this method is valid and efficient,and the result can be further analyzed with screening and visualization methods.
