Georeferencing a historical map using the David Rumsey Georeferencer provided valuable insight into the role of spatial humanities. I selected “City of Northfield original plat, 1905-1910, Northfield, Minnesota“, and worked through the process of aligning key landmarks between the historical and modern maps, transforming the image from a static artifact into a dynamic dataset that can be integrated into a contemporary geographic information system. The process involved selecting control points, adjusting distortions, and ensuring that the historical map corresponded as accurately as possible to its present-day location. Through this exercise, I gained a deeper appreciation for how historical spatial data can be preserved and analyzed!
This process changed my understanding of digital humanities by demonstrating how GIS tools do more than visualize geographic information, they also help reveal historical narratives, spatial inequalities, and patterns of urban development. Looking at the rectified map, I could begin to compare past and present landscapes, considering how infrastructure has changed over time and what these changes might indicate about broader social and economic transformations. I now see georeferencing as a method that enables scholars to not only document but also critically engage with spatial histories.
Examining the “This Map” page, I found that the georectified map is accessible in various formats, including web map services, GeoTIFF downloads, and direct web links. These formats allow for further spatial analysis in GIS applications or integration with other digital humanities projects. With a properly georeferenced map, the next steps might involve layering multiple historical maps to analyze transformations over time, extracting specific data points for research, or combining spatial analysis with qualitative sources to explore historical narratives in more depth.
Despite its usefulness, georeferencing comes with challenges. Many historical maps contain distortions, making it difficult to achieve perfect accuracy. Some landmarks may no longer exist, complicating alignment, and historical cartography often reflects biases, omitting certain communities or reinforcing colonial perspectives. Additionally, georeferencing is not always appropriate for research that lacks a spatial component or for cases where extreme precision is required.
Overall, this exercise reinforced the power of spatial humanities in uncovering historical and social dynamics. Georeferencing is not just about placing old maps onto modern ones—it is a way of visualizing change, interrogating the past, and providing new perspectives on the ways spaces have been shaped over time.

Hi Nina! I really like how you emphasize that GIS tools are not just for visualization but for revealing historical narratives and spatial inequalities. The idea of comparing past and present landscapes through rectified maps is really compelling—especially how changes in infrastructure reflect broader social and economic transformations. For challenges, I share the same concern with you. The discussion of distortions and biases in historical maps adds an important layer of critical thinking. It makes me appreciate how much interpretation and decision-making goes into Georeference!
