The Roman Empire established a road network that stretched tens of thousands of kilometers over Europe, Asia Minor, and North Africa. To add to this huge heritage, a team of academics led by experts from the Autonomous University of Barcelona and the University of Aarhus in Denmark created the most detailed and comprehensive map of ancient Rome's road system. This project's dataset, "Itiner-e," comprises almost 300,000 kilometers of roads at the height of the Roman Empire's growth (about 150 AD). The project combines centuries of archeological and historical study into a single, high-resolution digital map, including a dataset that expands the known network from 188,555 to 299,171 kilometers. To build the new map, Roman highways were identified using archaeological data, historical sources such as the Itinerarium Antonini (a document believed to date back to the second century AD that compiles the Empire's routes), and the "Tabula Peutingeriana". All obtained data was georeferenced using present and historical topographic maps, satellite images, and other remote sensing data before being manually digitized.
