People have georeferenced a lot of SF maps on OIM as well, you can explore them here: https://oldinsurancemaps.net/san-francisco-ca/

Email sent, and thank you! I should have mentioned this earlier, but folks can make direct tax-deductible donations to OldInsuranceMaps.net, which is now affiliated with OSM US's 501(c)(3) status. https://openstreetmap.app.n

That's basically what's going on, but it's all a manual process so far. The goal is scoped really just to the actual georeferencing and mosaic creation, no post-processing or OCR is performed on the maps within this platform

Absolutely, this would be incredibly cool, and if they can do it with burnt ancient scrolls it should be a cakewalk with these... Even just shining very strong light behind the pages you can see all the old layers. However, most of the LoC

This is something we need to add to the FAQ. There is some cross-compatibility already, in that OIM has endpoints to spit out Allmaps-compatible annotations from the database, e.g. https://oldinsurancemaps.net/iiif/reso

I started this project and couldn't be happier about this partnership with OSM US! Also here's a past HN thread with some more context: https://news.ycombinator.com/item?id=46788588

Thanks for sharing, this is really nice. I've added it to the list of other projects I have on the site [0]. Feel free to get in touch if you want to use OIM for other years of Paris, TX. [0] https://oldinsurancemaps.net&#x2

Thanks! Frankly the presentation side of the site needs a lot of work, and it's more about doing the georeferencing work, which sounds like you've already done. But you should get in touch I'd love to discuss further! I'

Yes, some maps in the site are hidden as they are part of an ongoing research project, just happens that Tampa and Key West are both examples of that. If you follow the blog/newsletter I'll surely announce when those are available

Yes, at certain points, like when I made that ohmg.dev website, I have looked at this as a re-deployable platform that anyone could self-host. It still technically is, but I've slowed down a lot on that idea (no one really showed up wi

No (or, not yet...) and yes, I know the Allmaps team well--it is an excellent project. There are a lot of similarities, but I would say two high-level differences are 1) OIM is built around server-side processing that immediately produces d

Hi! I added a page about "georeference-a-thons" recently here: https://oldinsurancemaps.net/community-georeferencing/

Yes, there are a number of maps (the FHA ones and also one Sanborn) that are part of a research project that is still in the works, so they are hidden for now.

by okok3857 8mo ago
Great question: no. I've spent a lot more time making the georeferencing side of things work well than improving search and discovery, and even presentation (like the /viewer/ pages), of the maps on the site. It's someth

I developed and maintain this site so I am both very happy to see it get posted here and also watching htop intently... I wanted to point out it is a crowdsourcing project, so every overlaid page you see has been placed there by a person, o

Fun fact: QGIS was originally written just to view PostGIS tables.

GRASS v.generalize() has a lot of different methods: https://grass.osgeo.org/grass85/manuals/v.generalize.html . I can't personally speak to the differences but probably worth looking into. The QGIS Simplify t

I don't see mention of OHM anywhere within TimeMap, is there something I'm missing? Is there a page about where the historical data comes from for the map?

You may be interested in OpenHistoricalMap: https://www.openhistoricalmap.org , which anyone can contribute to (you can read much more about it here: https://wiki.openstreetmap.org/wiki/OpenHistoricalMap ). E

This was an incredible aspect of the app to have when in Rome this summer! So many public water sources, and it was so, so hot....

Well, when I registered an LLC in the US, Google mailed me a postcard to confirm my address, and third-party providers begin calling to help "claim my Google listing". So they've really created an ecosystem that you immediate

Sure, I just mentioned it in the off-chance it was good enough out of the box. Big jump from making a screenshot (or perhaps stitching a few together) to editing OSM vectors in QGIS/Inkscape, which others have mentioned already.

The tile size doesn't change, but the number of pixels per meter does as you note--distortion being greater the farther you get from the equator (in the Mercator projection). The protomaps blog has some heady stuff you may enjoy readin

Can people add their own layers, like a WMS overlay? and, relatedly, have you considered adding georeferenced historical map layers? It seems like a good platform for story-telling.

Very cool you are using protomaps.js! I recently found their blog and really like the ideas in there: https://protomaps.com/blog

The Stamen toner map may work well for you: http://maps.stamen.com/#toner/14/37.8024/-122.2645 Also checkout their watercolor rendering... probably my favorite basemap that I never get to use. If you do use Q
