MigrO: a plug-in for the analysis of individual mobility behavior based on the stay region model

We present MigrO, a clustering environment for the extraction of individual mobility patterns from GPS trajectories, relying on the notion of stay region [1]. A stay region is an 'attractive' area where the moving object resides for a period, possibly experiencing arbitrary long periods of absence, before moving to a more attractive stay region. The core component is the SeqScan algorithm for the extraction of temporally ordered sequences of stay regions grounded on the notion of presence. An additional set of functionalities support trajectory pre-processing and clustering evaluation. MigrO is developed as plug-in for the open-source QuantumGIS system thus can exploit the rich set of functionalities of the hosting system, oering a formidable platform for the analysis of the mobility behavior. In this demonstration, we present MigrO at work in two case studies, both from the domain of animal ecology, illustrating two kinds of behavior, the migratory behavior and the exploratory behavior of two species of animals.
