Cover Story: Sixty-six new Roman military camps have been discovered in northwestern Iberia thanks to the combined use of different remote sensing techniques and open access geospatial datasets. We discuss the different spatial datasets and GIS tools used in geographic contexts of varied terrain and vegetation. We conclude that these methodological approaches stimulated by open access geospatial datasets are fundamental to understanding the Roman expansionism in Iberia. This renewed context sets up a challenging scenario to overcome traditional historical narratives still influenced by the cultural–historical paradigm and the pre-eminence of classical written sources.
