Combining historical records with modern mapping techniques, researchers mapped hundreds of thousands of kilometres of roads. The findings nearly double the known length of Roman roads.<\/p>\n The data set was published in Scientific Data on 6 November alongside an online platform called Itiner-e, which study co-author Tom Brughmans calls a \u201cGoogle Maps for Roman roads\u201d1.<\/p>\n \u201cIt\u2019s a growing resource for a community to keep on adding information to to ensure that this remains the best representation of our knowledge of where all the roads in the Roman Empire were,\u201d says Brughmans, an archaeologist at Aarhus University in Denmark.<\/p>\n Brughmans hopes the data set will \u201crevolutionize our understanding of how people, ideas and infectious diseases\u201d spread 2,000 years ago. \u201cSuch insights can be used to better understand the challenges we face today,\u201d he adds.<\/p>\n Source: itiner-e.org<\/span>Roman Routefinder: Map showing high resolution mapping of the ancient Roman road networks, around 150 AD, revealing nearly 300,000km of main and secondary roads.<\/span><\/p>\n Previous attempts to map the road networks of the Roman Empire had created incomplete data sets with low spatial resolution, and estimations for road locations rather than evidence-based reconstructions.<\/p>\n \u201cAlthough the roads are one of the best-known aspects of Roman history, it\u2019s surprising how many details about them we still don\u2019t know,\u201d says Catherine Fletcher, a historian at Manchester Metropolitan University in the United Kingdom.<\/p>\n The researchers first identified Roman roads from previous studies, including atlases, surveys, historical sources, archaeological sources and existing milestones. They then compared this information to modern and historical aerial photographs, topographical maps and satellite imagery. The team digitized each road section with a high spatial resolution, then combined the sections into Itiner-e.<\/p>\n The map includes nearly 300,000 kilometres of roads existing in around ad<\/span> 150, when the empire was at its maximum territorial extent.<\/p>\n Higher spatial analysis allowed the researchers to map 200,000 kilometres of secondary roads. By combining different sources, the researchers could map winding roads crossing difficult terrain with more accuracy, thereby improving on previous estimates based on unrealistic direct lines over, for example, mountain passes.<\/p>\n The data set also reveals that the locations of only 3% of Roman roads are known with certainty. A further 7% are considered hypothetical, because they have been identified but not precisely located or verified across sources. The remaining roads are conjectured and based on fewer documented sources.<\/p>\n \u201cThis was a huge surprise and a sobering realization,\u201d says Brughmans. But \u201cthat 3% certainty figure isn\u2019t a failure; it\u2019s a \u2018call to action\u2019 that gives us a precise confidence map of what we don\u2019t know and where to look next\u201d.<\/p>\n","protected":false},"excerpt":{"rendered":" A data set nearly doubles the known length of roads used during the Roman Empire.
