Swedberg develops PerSE for periodicity analysis

Brian Swedberg has developed PerSE (Periodicity in Spatiotemporal Events): a web application designed to aid users in the detection and analysis of periodicity in spatiotemporal event data sets. A key advance of PerSE is the ability to handle variable spatiotemporal scales and calendar systems. PerSE is composed of several cross-filtering views: the Map, Attribute View, Time-Wheel, Time-line, and Table. Users interactively set and release filters on one or more of the views to detect and analyze calendar related periodicity.
