This is an innovative map series I created for my research, in exploring the spatiotemporal pattern of twitter-based trajectories during 2017 Hurricane Harvey. Specifically, the trajectories are moved to the centroids of aggregated units in proportion to their distance, according to their origins or destinations. By keeping the same direction and same amount but rescaling the distance, the overall pattern of each state’s trajectories is clearly displayed in one map.

The interactive version in Mapbox is available ( by origin and by destination ). An integrated webpage of the Hurricane Harvey is also available here , including an interactive comparison map (below).
