About Itiner-e

Itiner-e aims to host the most detailed open digital dataset of roads in the entire Roman Empire. The data creation is a collaborative ongoing project edited by a scholarly community. Itiner-e allows you to view, query and download roads. Each road segment has a URI that allows it to be cited and linked by external resources. It also includes a route-finding tool to explore travel itineries and times in the ancient world (beta version).

Download Full Dataset

Every night a full export of all route segments is created in ndjson format, where each line is a json route segment object.

A route segment object is structured like a GeoJSON LineString object with an additional property pleiadesPlaces representing the pleiades places in the vicinity of the route segment (only applied for roads, not for rivers or sea lanes).
