As a follow up to Elizabeth’s post last year, I tried to “play with” the old map Elizabeth was using and see if I could crate any meaningful mapping out of it. First, as Elizabeth previously pointed out, this old map is quite difficult to use, since there are a lot of places in the map that do not have a similar spacing or arrangement in a modern map. As a result, instead of trying to superimpose this old map to a modern map (e.g. google maps) and geocode it (i.e. “georectifying” the map on a software like ArcGIS), I used a tool called Antirubbersheeter created by Moacir P. de Sá Pereira to annotate the map.
Here is what the old map looks like again:
In annotating the map, I went to the website and followed the instructions. First, I uploaded the image that I wanted to use (i.e. the old map of Rome above). This image would then also be uploaded to imgur. Then, I listed a few places that I wanted to mark on the map one by one separated by commas on the geocode box. Due to my minimum knowledge of Rome geography, I only picked four places: Papal Palace, Castel St Angelo, Pantheon, Colosseum.
After clicking on Geocode, now I can start on geocoding the places that I specified on the homepage. For each place, I saved the geocode and proceeded to the next.
Again, my knowledge about Rome is extremely limited, so I might have made a lot of errors in geocoding my places. After saving everything, Antirubbersheeter gave me a .json file that refers to my now annotated map. Here is the final result:
