Large-Scale Spatiotemporal Data Analytics and Learning
Project Description

A spatial trajectory is a trace generated by a moving object in geographical spaces, where a moving object can be any entity whose locations can be continuously captured using location positioning devices or monitored by various types of sensors. With the rapid development of location-positioning and sensor systems, navigational and social network applications, wireless and telecommunication technologies, a myriad of spatial trajectory data has been available representing the mobility of a variety of moving objects, such as people, vehicles, assets, animals, and natural phenomena. Spatial trajectory data is a typical type of big data, featuring extremely large volumes, a high level of structure and semantic diversity, and the dynamic and streaming nature of the data and the related environment. They contain rich information to monitor and to discover the relationship for moving objects and locations at an unprecedented scale. Spatial trajectory data management and analytics are fundamental technologies to enable intelligent transport systems, location-based services, resource tracking and scheduling, emergency responses, urban planning, IoT and smart city, to derive values from big spatiotemporal data.

This project is part of our leading research to develop a highly scalable, quality-aware, general-purpose, and open system to manage spatiotemporal data. We will focus on new computing and database platforms and machine learning models to support descriptive, predictive and prescriptive trajectory data analytics.
