Analysis of spatio-temporal data has become critical with the emerge of ubiquitous location sensor technologies and applications keeping track of such data. Especially with the widespread availability of low cost GPS devices, it is possible to record data about the location of people and objects at a large scale. Visualization often plays a key role in the successful analysis of location data. Due to the complex nature of this analysis process, current approaches and analytical tools fail to effectively help spatio-temporal thinking and contribute to solving a large range of problems. In this work, we propose an interactive visualization tool to support human analyst in understanding user behaviors and location patterns and anomalies in massive collections of spatio-temporal data. Our tool, which combines a geovisualization framework with 3D visualizations and histograms, is tested by a real mobile service dataset with almost 1.5 million rows.
