The potential of geospatial technologies and open data in planning history

Abstract

Digital tools and related open datasets, particularly for geospatial analysis, provide an opportunity to connect planning history more closely to the methods of planning practice and heritage itself. While contemporary planners have adopted advanced, data-driven tools to model urban systems and environmental risks, planning historians have largely kept relying on traditional methods, such as static cartography and archival interpretation. This disconnect has contributed to a widening gap between planning practice and its historiography. Drawing on historical examples, such as Maurice Rotival’s pioneering use of computers in planning, and recent digital mapping initiatives, this paper argues for a more integrated, interdisciplinary approach to planning history. It examines how digital platforms, datasets and analytical tools can improve spatial and temporal analysis while maintaining critical historical inquiry. The paper discusses practices such as GIS-based analysis, digital inventories and dashboards, and reflects on institutional and methodological barriers to wider adoption. Engaging with the digital turn enables planning history to evolve beyond biographical and text-based traditions, offering richer insights into the urban past and informing more sustainable, just and historically grounded futures.
