The project which I have chosen to blog about this week which integrates historical research with GIS technology is a project at the University of Western Ontario called Imagining London. One of Imagining London’s central researchers is Dr. Jason Gilliland whose projects include studies of the evolution of London, Ontario due to natural and anthropogenic forces. For example, current projects include a study using GIS technologies of the impacts of fire on not only the physical form but also social form of the city. An additional project is the impact of flooding on London, Ontario, in particular the floods of 1883 and 1937. One interesting element of this project that I discovered is that the home base of the project is not a room lined with books, or as many of us might envisage, the library, but the Human Environments Analysis Laboratory. In terms of the question of how GIS technologies are useful to scholars and to myself, there are a few answers that seem to jump out. Imagining London perhaps cynically suggests that GIS tools are advantageous in history because they are practical and good for employment. One could also state, as MacFadyen suggests, that one of the biggest strengths of using GIS, in this case in conjunction with aerial photography, is that it breaks down academic walls and offers and interdisciplinary approach. This seems sensible as the study of physical landscapes, even in a historic sense, may necessitate a basic understanding of concepts such as erosion, forest succession, among others. In this blog post, I would like to delve a bit deeper into the topic and speculate that the most effective use of GIS technology is not in the tangible ways it helps historians approach a topic, but in how it allows historians to relate a topic to their audience.
I became familiar with Joshua MacFadyen’s work, in particular his work with aerial photography, last semester in Dr. Catherine Carstairs’ HIST*4220 Canadian Cultural Identity course. The blog entry which piqued my interest the most was his blog post “Exposing Nature: Aerial Photography as Witness and Memorial in Bonshaw, Prince Edward Island.” This article touches on the proposed re-routing of the Trans Canada Highway through an endangered tract of Hemlock forest in Strathgartney Provincial Park. This proposition triggered outrage from locals which resulted in the Prince Edward Island government proposing a second plan called Plan B which essentially changed the route but not its ecological impact. These events caused local residents to set up protest camps and launch a campaign called Stop “Plan B.” Using aerial photos collected between 1935 – 2010, MacFadyen reveals the untouched nature of the tract of Hemlock amidst agricultural development and disturbance. What is significant about this article to me, is that MacFadyen uses digital technology not only to document historical development in the area (or lack thereof) but to allow people to experience history and to give that experience meaning. That, to me, is the most valuable usage of GIS technology.
In my opinion, it is the idea of experience which has allowed the use of GIS technology to gain a substantial following amongst historians. MacFadyen himself explains this in “Mobile Mapping and Historical GIS in the Field” that it is “…in order to experience a place…” that one must understand it in its context. In this sense, GIS technology enables history to be learned not only through books, journals, and research, but through experience as well. Even in reference to Anne Kelly Knowles’ study of the Battle of Gettysburg, Tony Horwitz describes Knowles’ objective as follows: “…she wants to know what commanders could see of the battlefield on the second day at Gettysburg.” It is this idea of experiencing history which motivated Knowles in the first place as a child on trips to national historic sites in the United States. I think Nick also touched on this concept in his own blog entry. Using digital satellite mapping technologies, it becomes not only possible to identify the foundations of pyramids, but to visually reconstruct them and experience them a form closest as possible to their original form.
In terms of how GIS technology will be useful to myself, this week’s assignment has given me some new ideas for my project this semester and, come next Tuesday, I would like to investigate the possibility of a GIS project for the city of Guelph perhaps even integrating aerial photography if such resources exist. This would give me a potential opportunity to expand my knowledge of a city which most of us experience on a daily basis and perhaps add historical context to that experience.
Additionally, for those interested, I have done some digging on the “Plan B” highway. Protestors have been removed from their camp by the RCMP and it seems as though the project will continue.
