Geo-spatial big data analytics

Developing technically sound and efficient solutions for mobility data collection and analysis from machine-generated sensor data poses multiple challenges in terms of storing and retrieving massive spatial-temporal datasets, extraction of useful mobility information from incomplete and possibly inaccurate sensor and transportation network datasets, and intuitive visualization of both raw data and analyzed mobility data. AIT has profound competencies in big data and geo-spatial database management, statistical learning, and visual analytics and contributes to the relevant scientific communitites.
