Hi all! I am trying to make a map of an area of Rome with 17th century street names and buildings. Can I do this over the actual map? Thanks!

This would seem to be a bit difficult in OSM itself. While it is completely possible to store an old_name attribute for a street or building, there is no time dimension as such, so there can really be only one such tag per object currently.

Possible solutions:

  • customize a local extract of OSM data, replacing the value of name tags with the ones of your choice. This is reasonably easy, but you will have to render the data yourself (which would be quite easy with tilemaker for vector tiles).
  • investigate using https://openhistoricalmap.org/

Thank you! I will look into it. Hopefully, there is a way to do it along with demarcating the shape of old buildings. I am new to this and don't understand much but I'm a fast learner. Thanks again!

Technically, it's possible to extend date ranges to old_name like e.g. old_name:1921-1932=abc. But there would be many unanswered questions on how to treat historic dates in different calendars. You would also just attach the old name to the current streets without any adjustment of position or adjacent building structure. So looking at OpenHistoricalMap is probably the better option.

I'd recommend to contact https://wiki.openstreetmap.org/wiki/User:Dieterdreist (his personal website is https://23maps.it/en ) as he has done this in a wonderful way in his nolli-app (https://www.nolli-app.com ).
