Gerrymandering, a process of spatial exclusion and marginalization, has a long and sordid history in the United States. The upcoming 2020 US Census and subsequent need for alterations to political districts are again bringing this topic into focus. GIS has been identified among the best tools for identifying and preventing this practice. However, most GIS analysis of gerrymandering (or, indeed any spatial phenomena) to date has relied almost exclusively on approaches that use absolute representations of space (O’Sullivan et al. 2018). Yet these strictly Euclidean perspectives may fail to account for inequalities that continue to exist in alternate—but very real—relational and experienced spaces. To this end, we revisit the quantitative revolution in geography, a period during the 1960’s and 70’s when researchers (Tobler, Harvey, Bunge, Forer and others) were exploring new ways of representing space. While these perspectives offered exciting new insight, these types of transformations required complex mathematical computation and methods that were not yet well-developed. These technical challenges were among the many reasons that the pursuit of these types of visualizations were largely abandoned. Using new and improved computational tools, we hope to improve upon these efforts, providing a process for generating new visualizations that explore these relational spaces within congressional districts. Specifically, we look at representations of space as travel time, not distance We also discuss the challenges, successes, and future applications of this tool for providing new representations of the complex and dynamic relational spaces that exist all around us.
