This project has two primary objectives. First, to present an interactive map of the Roman Empire as it existed at the end of AD 130—coinciding with the foundation of Antinoopolis—using modern web technologies. Second, to create a unified reference point that connects disparate scholarly databases of ancient Roman settlements by aggregating their identifiers and cross-references in a single, accessible location.

The project is built with OpenLayers v8 and utilizes multiple GeoJSON layers. The base map, including coastlines and provincial boundaries, is derived primarily from the Ancient World Mapping Center. Numerous geometric errors in the original data were corrected, and several provincial borders were adjusted to align with relevant geographic features. Every settlement is linked to the Pleiades gazetteer and, with few exceptions, to both the Barrington Atlas and the Digital Atlas of the Roman Empire.

The road network depicted on the map is based on data from Itiner-e: the digital atlas of ancient roads. It classifies routes by their level of archaeological and historical certainty (certain, conjectured, and hypothetical).

Data on urban ranks is derived from Hanson, J. W. (2016). Cities Database (OXREP databases). Version 1.0. Used with academic attribution. Please consult the original source for terms of reuse.
