Exercise 5
Mapping the Past and Historical GIS
Confirmed positive cases of COVID-19
When I began this exercise, I wanted to map the first few individuals that had positive COVID-19 cases in Toronto. However, I quickly faced some challenges during my research due to unreliable or lack of informative sources. Many of these sources were inconsistent and I felt that relying on them would have resulted in a sparse, and potentially inaccurate map.
This topic is a sensitive one at that, and I wanted to make it as accurate as possible. The only repetitive case documented in any source begins with a man in his 50s, who travelled back with his wife from Wuhan, China in January 2020. With this data as a starting point on a map, told very little to tell a broader story of a deadly pandemic we all experienced.
This led me to increase the geographic scale to the whole province of Ontario.
After looking at numerous numbers of different sources, I finally found a promising one: a dataset published by the Government of Ontario that tracked nearly a million cases from 2020-2024. I aimed for a story mapping focus of administrative geography. I think mapping adds dimension that the dataset contents could not reveal. Although the one I created is an amateur's work, I hoped to connect the PHUs who reported their cases to show the virus' travelling. I also found the region who had the highest number coronavirus reports: Toronto Public Health. This would make sense for a densely populated city and everyone being in closer proximity.
I think spatial history emphasizes connection, showing what was happening in all places in a range of time. Additionally, I think that digital tools pose the challenge of choosing what data is left out for the visual narrative because of the geographic focus.
I know this was simply an exercise but if I were to do a full project on this topic, I think I could create a great story map with just using ArcGIS.
p.s. I also tried StoryMapJS, I like the simplicity, but I would prefer ArcGIS for its visual components.
