This is really cool, makes me nostalgic for a lot of time georeferencing random maps from the library of congress or from municipal archives etc.
In that same vein, you could add a feature where users could contribute georeferenced map files for community review and approval--I think that would really increase your scalability. I see you have an email for that currently.
I love love love this direction. And yea, I have a basic email but I really think a super simple upload and maybe even dead-easy georeference tool for folks to contribute data is a no-brainer! I'm bumping this up on my backlog, thank you!
Amazing, can't wait to see where you end up! Let me know if you need a hand too. I love web mapping projects--I got into programming through QGIS/leaflet on the way to a couple degrees in GIS and urban planning.
