Visualizations of Historical Spatial Data as Tools of Exploration and Education

Based on pilot studies conducted in the DigiKAR geohumanities project, which analyzes spatial relations in the Holy Roman Empire of the seventeenth and eighteenth centuries, this paper explores the value of iteratively and experimentally visualizing spaces in historical research. Bringing together interdisciplinary researchers as well as heritage professionals and students, the current pilot phase of the DigiKAR project uses maps for high-level data evaluation, data cleaning and educational purposes. At a later stage, more elaborate visualizations as tools of science communication will ensue. Throughout our research process, visualizations are closely linked to historical and contemporary narratives across media genres. Visualizations rely on textual sources and correspond with the academic texts we produce. Our experiences are meant to inspire other humanities projects, especially in historical subject areas, to experiment with visualizations even on a technically basic level, and even when sources are incomplete, fragmented or uncertain.
