We propose a two-pass strategy for mining and manipulating spatio-temporal datasets at different levels of detail (i.e., granularities). The approach takes advantage of the multi-granular capability of the underlying spatio-temporal model to reduce the amount of data that can be accessed initially. The approach is implemented and applied to real-world spatio-temporal datasets. We show that the technique can deal easily with very large datasets without losing the accuracy of the extracted patterns, as demonstrated in the experimental results.||Funding Details:||Science Foundation Ireland; Irish Research Council for Science, Engineering & Technology||Type of material:||Conference Publication||Publisher:||Springer-Verlag||Copyright (published version):||Springer 2008||Keywords:||Spatio-temporal data mining; Spatio-temporal multi-granularity||Subject LCSH:||Data mining
