04_OD Flow Explorer Case Studies

The Geoinformation and Big Data Research Laboratory (GIBD) at the University of South Carolina developed the OD Flow Explorer (http://gis.cas.sc.edu/GeoAnalytics/od.html), which provides free human mobility data derived by global wide Geotagged Tweets and the US Safegraph data. To make the data analysis reproducible, replicable, and expandable, we created three case studies based on workflow to visualize data in dynamic maps, and analyze human mobilities' impact on COVID-19 disease transmission in the US and Europe.
