That's really cool! Just wanted to share the following site as the city of Toronto created something similar a few months ago https://map.toronto.ca/torontomaps/

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 it! A suggestion for much further down the line: a timeline on the map which composites many maps from a similar time period so you can see them all stitched together (somewhat like how https://skyvector.com/ stitches together multiple sectional charts into a continuous map, though I know it can't be as seamless). Or you could attempt to run some extra processing steps to warp the map to match the background map's projection. Those are both big undertakings, though.

Your site is similar to https://www.oldmapsonline.org/

I have found the ui for map difficult to use in the past.

Obviously I want to buy a high quality print of the map focused on an area.

Damn, for a second I thought this was like weedmaps but for linguini (which would be an awesome site) and then I looked a bit closer. Still cool though!

Have you thought of running super resolution on the images?

I found a map of the area around my family’s farm in 1894 super quick. Awesome site!

This is super cool, thank you for making it!
