Some maps were never meant to be georeferenced, and the Peutinger Map is one of them. Here are some nicely scanned versions of its sections.
But I do respect the efforts that some have made to scrape off the locations, do some creative and researched geocoding, and provide scholars with a digital tool that may provide an insight or two. This is a new one that I just learned about, the Omnes Viae. Locations are based on Richard Talbert’s work.
