The Laboratory of Compuational Spatial Science for Sustainability (COMPASS Lab) is a research group in the School of Geoscience at University of South Florida. The COMPASS Lab conducts research on GIScience and Spatial Data Science to promote resilience and sustainability of human communities facing natural hazards and climate change. The lab is led by Dr. Yi Qiang, an Assistant Professor at USF Geosciences.
The Lab is organizing Symposium of Scale in Spatial Analytics and Modeling during the 2022 Annual Meeting of AAG 2022. Learn more details from
here.
The website
of the CroScalar project is online. Tools and sef-paced tutorials about the multi-scale spatio-temporal modeling framework (MSTF) will be available in this website soon.
We welcome graduate and undergraduate students interested in GIS and spatial data science to join our lab. Funded Ph.D./MA position available in 2022 Fall.
We use night-time light remote sensing images to detect economic disturbance and recovery in natural disasters. Our study demonstrates that NTL remote sensing is a low cost, efficient and large-scale data acquisition method to analyze community resilience.

We use crowdsourced traffic data in Google Maps to monitor road network condition in extreme weather events (e.g. a winter storm). We found that accessibility to critical facilities reduces due to weather impacts and the recovery process differs in different places. This method can provide support for emergency response and assessment of road network resilience.

We used GIS and digital elevation models (DEM) to map ocean visibility in Oahu, Honolulu. The result shows that oceanview is unequally shared by different population groups. Also, the oceanfront high-rise buildings has caused significant

We conducted national assessment of flood exposure of population and critical infrastructures. It is estimated that 21.8 million (6.87% of) U.S. population are exposed to 100-year-flood in 2015. At a national scale, economically disadvantaged population are more likely to reside in flood zones than outside. At a local scale, this trend varies at different places. Our studies provides baseline information for policymaking at different levels of administration and pinpoints local areas where diversified and ad hoc strategies are needed to mitigate flood risk.

Compass was invented in China during the Han Dynasty (200 BC - 100 AD) where it was called the "south-governor" (sīnán 司南). The original form of compass is a spoon-shaped lodestone placed in the center of a plate. In the Age of Exploration, compass had a profound influence on geography and the shaping of the world. In the 21st century, the COMPASS Lab leverages data and computing revolutions to study environment-human interactions for a sustainable future.
