This session will revisit topics, themes and questions concerning the use of geographical information systems (GIS) applications and techniques in historical research and teaching discussed at a 2015 AHA session prompted by Alexander von Lünen and Charles Travis’ History and GIS: Epistemologies, Considerations and Reflections (2013). Over the past decade, GIS has made its presence known in historical research, pedagogy, and disciplinary outreach and consultation. GIS methods and technologies are increasingly being utilized in libraries, and digital archives to curate and disseminate historical data, records, documents, cartography and geodata via online collections such as the Library of Congress, the Newberry Library, the David Rumsey Historical Map Collection, IMPUS, Social Explorer and other platforms. Historical GIS attribute data tables are increasingly being sourced for public and private historical records to create visualizations and analysis. Such GIS functions are deployed not only for projects in history and historical geography, but in the Spatial and Digital Humanities, and filmic- visual and interactive online representations of historical events, dynamics and processes. Anne Kelly Knowles’ Past Place, Past Time: GIS for History (2002), John Lewis Gaddis’ The Landscape of History: How Historians Map the Past (2004), Ian Gregory and Paul Ell’s Historical GIS: Technologies, Methodologies, and Scholarship (2007) and David J. Bodenhamer, John Corrigan and Trevor M. Harris’ Deep Maps and Spatial Narratives (2015) alongside von Lünen and Travis’ History and GIS, have served as touchstones for scholars engaging humanities focused geospatial technology tools and methods. Work in historical GIS has expanded to explore the various framings, scales, cycles and concepts of time by which humans have recorded their existence and events (e.g. Mesoamerican Codices, Kairos and Chronos time, Julian and Gregorian calendar systems, Braudel’s l’histoires & longue durée, Einsteinian relativity, etc.) This session explores how historiography and geosophy have been impacted, broadened and / or limited in scope by GIS applications, technologies and methods, ranging from deep mapping, charting, digital gazetteers, to cliometrics. Session papers will discuss qualitative, quantitative and mixed-methods GIS case studies, in addition to providing an overview of current proprietary and open-source geospatial platform suites that facilitate historical research and teaching. More fundamentally, the session will focus on GIS mapping and data curation as research methods that scholars can engage, in to write the narratives of visual history, in distinction to simply engaging GIS as a tool for drafting the static map of an event, process, etc., to illustrate the findings of a discursive, historical narrative.
