ESRI App Challenge 2019

Two Undergraduate Students (David Recchia and Sun Park) Postdoctoral Research Fellows (Drs. Seungho Yang and Pio Claudio) from our lab participated in the ESRI APP Challenge 2019. The name of this team is “Tim Hortons” who have developed a GIS App, called Sustainable Urban Networks (SUN). This application allows users to calculate the time difference between public and private transportation accessibility. They aim to visualize travel time differences between the two transportation modes and ultimately relate this to transportation justice issues. The Tim Horton Team will continue to extend this project during this Summer.
