The 2023 University of Toronto Geospatial Data Visualization Challenge
In Fall 2022, Esri Canada and the University of Toronto Dalla Lana School of Public Health (DLSPH) initiated a three-year strategic collaboration to foster and spotlight the application of location intelligence and GIS in Canadian public health research. I co-lead the collaboration, along with Dr. Laura Rosella, associate professor and director of the DLSPH Population Health Analytics Lab.
To celebrate this unique and exciting program, we hosted the very first University of Toronto Geospatial Data Visualization Challenge from February 2 -10, 2023.
We asked DLSPH students to assemble a student team from across the University to develop an ArcGIS story map based on a public health issue of their choice for cash prizes. Esri Canada partner Environics Analytics donated their high-resolution data for the challenge. To up the ante, we gave the winning team a spot to present their solution at the 2023 Esri Canada GIS in Education & Research Conference held in early March at the University of Toronto’s Hart House.
After only one week – and with limited GIS backgrounds – five teams submitted astounding story maps.
The teams used geospatial methods and visualizations to evaluate a range of public health issues in Ontario—from child poverty and food access, to the opioid crisis, to physical activity and well-being. I was amazed by how innovative the teams were in integrating Environics Analytics data into their analyses to highlight new geographic insights about these current issues. Suffice to say, the judges themselves were challenged with choosing the top three teams, given how impressed they were with the final results.
The judges included Jo-Ann Osei-Twum, MSc, PhD candidate and DLSPH Data Science Fellow, and Jeff Allen, PhD, data visualization lead of the University of Toronto’s School of Cities. They evaluated each story map based on creativity, geospatial methods and scientific communication. Despite the stiff competition and impressive deliverables, the judges announced these winning teams:
Jonathan Sinn, Rachel Ma, Nicholas Chu, Anne Campbell, and Gabriel Tjong
Mission Statement: To demonstrate the severity of child food insecurity in specific areas across Toronto and to put forth recommendations on how to address this public health crisis.
Judges felt The Covariates produced an especially insightful and beautiful story map based on their innovative overall approach to evaluate child poverty in Toronto, the broad integration of open data (e.g., material deprivation, modified retail food environment index, etc.), advanced spatially explicit epidemiological modeling, and streamlined communication of results and recommendations to appropriate stakeholders.
The judges agreed that each of the teams’ submissions were unique, provided new insights in public health challenges, and were impressive despite the one-week deadline.
The students were able to quickly learn ArcGIS. As exclaimed by winning team member Jonathan Sinn, “The Geospatial Data Visualization Challenge was a great hands-on experience to use ArcGIS. We leveraged a wide range of tools, including hot spot analysis and geographically weighted regression, that were key to formulating public health recommendations on how to address the growing crisis of food insecurity.”
