Research theme: Smart City and Big Data

The recent explosive publications of big data studies have well documented the rise of big data and its ongoing prevalence. Different types of “big data” have emerged and have greatly enriched spatial information sciences and related fields in terms of breadth and granularity. Studies that were difficult to conduct in the past time due to data availability can now be carried out.

The aim of this research theme is to enhance our understanding of the cities through various applications of big data.
