Abstract: Provided are a device and method for analyzing spatiotemporal data of a geographical space including one or more regions. The method includes imaging spatiotemporally varying data, selecting a representative image according to each transition state based on a spatiotemporal change in the imaged data, grouping pixels in the selected image by clustering the pixels, and performing group-specific data analyses.
