A public space for georeferencing (and exploring) historical fire insurance atlases ~ https://oldinsurancemaps.net ~ app development on GitHub: https://github.com/ohmg-dev/OldInsuranceMaps
in brief: with multi-page georeference atlases, you need to trim the margins of overlapping sheets, and OldInsuranceMaps.net has a really nice way of doing it. Complete with snapping and (now) vertex styles that make it easy to clean things up

If this works
add_raster_source(url={https://oldinsurancemaps.net/map/sanborn09064_003/main-content/tilejson}, id="OIM")
it would be better. Technically the XYZ url could change (if the mosaic file is regenerated), but the TileJSON url will stay the same.

Fantastic :) I only recently realized how useful tilejson is and added it throughout the site. Glad you found it! Now to update the docs.....

Great! What OIM endpoint are you using to get the map?

@ktflghm.bsky.social - I'd say @openhistoricalmap.org is the closest thing to Pastmapper these days & I even made fun of how little progress has been made since PM's glory days in a slide a few years ago... @mradamcox.bsky.social's oldinsurancemaps.net is my go-to for Sanborn mosaics.
