GEAR Lab Publication on Measuring Resilience with Big Earth Data

Dr. Lei Zou from the GEAR Lab recently published a collaborative article in the Big Earth Data Journal providing a comprehensive review of community resilience definitions, along with the traditional and emerging data and methods of quantitative resilience measurement. The article is led by Dr. Yi Qiang from University of South Florida and in collaboration with Dr. Heng Cai from Texas A&M. The details of this publication can be found below:
