Oldinsurancemaps.net is now a Charter Project

I wish AI leaders would fund more data archival projects, instead of hoarding it themselves. They could build a lot of goodwill, but the current state of the art is destroying old books and denying anyone access to them.

These archival projects have an enormous impact, though they are chronically underfunded. I wish there were a strong economic incentive to support them.

Anthropic just learned to the tune of a 1.5 billion dollar settlement that making available for human consumption, even internally, instead of hoarding for AI training exclusively is a fraught exercise.

SourceLibrary.org for instance… how to make what is done there an economic value for AI companies with data for training?

Great resource. Fire insurance maps are goldmines for urban history research.

If you like old maps you can check the french maps with historical layers (17xx, 1880, 1950, today) :

https://cartes.gouv.fr/explorer-les-cartes/

you can add and remove layers by clicking on the map icon on the top right.

Having these maps under a charter means long-term maintenance isn't just one person's side project anymore.

On visiting the actual oldinsurancemaps.net, I was met with:

"OldInsuranceMaps.net is a Charter Project of OpenStreetMap US that provides an open, online workflow for creating georeferenced layers of historical maps, with a special focus on making seamless mosaics from multi-page atlases in the Sanborn map collection at the Library of Congress."

What the hell does that mean? Anyone to ELI5?

Sanborn was an insurance adjacent company that made detailed paper maps of many towns in the US in the late 1800s and early 1900s.

This project is scanning those maps and adding the information that modern mapping software needs to show them alongside other geographic information. Where the old paper maps overlap, they work to cleanly stitch them together rather than showing the edges of the paper.

Later: The project is sort of for people looking for the old maps, so I can see why the introduction doesn't spend a life of time explaining them.

ELI5:

They are building computer programs that other people can use to then post online maps from old paper sources. For example, from the Sanborn map collection.

Those maps can be browsed as "overlays" on top of other maps, so you can easily compare how several maps show the same places on Earth.

They make a nice way of stitching together old maps.

Fantastic project.
