Spatiotemporal Exploration and Visual Analytics

Our spatiotemporal visual analytics research involves analyses  of events, people, places, and resources that vary over time.  We have developed novel, patented spatiotemporal predictive analytics techniques and useful deployed systems for use in resource allocation, workload prediction, scheduling, and logistics management.  Our predictive/correlative and other analytics research within its spatiotemporal suite of tools enables users to better:

• Explore and understand complex datasets.

• Understand potential patterns at different scales and in different spaces/environments.

• Employ the outcomes from the datasets for effective decision-making.
