Analysing Roman itineraries using the GIS tool: the case of the road XIX

Abstract Reconstruction of the Roman road network must be approached from various methodologies of multidisciplinary character. When traditional approaches have been exhausted without achieving a historiographical consensus, the problem may appear insurmountable. However, leveraging Geographic Information Systems (GIS) provides an avenue for re-evaluating existing proposals and suggesting more fitting layouts. This can be accomplished through a meticulous analysis that incorporates topographic and non-Euclidean correlations, allowing for a more nuanced and accurate understanding of the subject matter than conventional methods might offer. We explore a case study in the Galician territory, where we have detected methodological shortcomings when it comes to being able to identify and reconstruct the route of the XIX road: Item Bracaram Asturicam . One of the sections that has aroused the most debate is the case of Tude to Lucus Augusti , based on several basic problems that are the identification of the mansions , the lack of consensus in the measurements of the distances of the miles referred to in the classical sources, and the complex orography of this territory. To propose answers and theories that solve the current problem of the description of this route of the XIX road, it is proposed a work that, through applications of Geographic Information Systems, settles the debate of the current state of the question.
