Spatial Big Data

Abstract

This chapter discusses the concept of spatial big data, as well as its applications and technical challenges. Spatial big data (SBD), e.g., earth observation imagery, GPS trajectories, temporally detailed road networks, refers to geo-referenced data whose volume, velocity, and variety exceed the capability of current spatial computing platforms. SBD has the potential to transform our society. Vehicle GPS trajectories together with engine measurement data provide a new way to recommend environmentally friendly routes. Satellite and airborne earth observation imagery plays a crucial role in hurricane tracking, crop yield prediction, and global water management. The potential value of earth observation data is so significant that the White House recently declared that full utilization of this data is one of the nation’s highest priorities.
