A High-Resolution Dataset of Roads of the Roman Empire: Itiner-e static version 2024

This dataset represents the 2024 canonical version of the Itiner-e dataset, described in the publication by de Soto, Pažout, Brughmans, et al. in Nature Scientific Data (2025) https://doi.org/10.1038/s41597-025-06140-z. A growing version is hosted at https://itiner-e.org. Itiner-e is the first comprehensive and spatially detailed digital dataset of the roads of the Roman Empire (ca. 300 BCE-300 CE). It has been created by (1) identifying roads based on existing scholarship including atlases, regional summary publications, survey reports, excavation reports, gazetteers and milestones; (2) localizing roads using modern and historical topographic maps, and aerial and satellite photography; (3) digitizing roads and their metadata, and cleaning the data. The principal contributing institutions are Aarhus University (project MINERVA, PI Tom Brughmans, lead road data collection Adam Pažout) and the Universitat Autònoma de Barcelona (project Viator-e, PI Pau de Soto) with numerous collaborators from other institutions (see 'Creators').
