From some recent activity, here's a rare but good example (from Worcester Mass.) of where the Thin Plate Spline transformation makes sense for #georeferencing #sanborn maps. Curved roads out in space are sometimes drawn without good scale and need extra distortion oldinsurancemaps.net/layer/72727

If you are in the New Orleans area, come to one of our upcoming Georeference-a-thons at Second Line Brewing! Tuesday evenings, the 16th and 23rd. RSVP form here: tiny.cc/georef-2025. We'll be focusing on 1895 Duncan Plaza area and hearing from archaeologists who did work there over the summer.

This started as a "here's a link to a recent talk recording" but I ended up repurposing some slides and writing more about how the warping process works within the system.

Are there any options for running a serverless patterned STAC endpoint? Or even better, a fully static STAC-metadata store that requires the client to do the filtering?

I see that https://github.com/stac-utils/stac-fastapi can use a parquet storage as its backend, which seems like it could get […]

The six-year Sanborn copyright case has been settled! Started with EDR (now LightBox) suing ERIS and right away ERIS counter-sued with a lot of claims. Looks like ERIS came up big in the settlement with a valid license to distribute all copyrighted Sanborn maps: www.businesswire.com/news/home/20....

If a foreign adversary snuck into our Federal budget and cut science research and education the way we’re cutting it ourselves — strategically undermining America’s long-term health, wealth, and security — we would likely consider it an act of war.

We spent an entire paddling season researching and paddling across the Twin Cities to create this guide. The Star Tribune has never put out a guide this comprehensive. Get out on the water, people. It's really the best thing you can do this summer.

We plan to use @overturemaps.bsky.social Places data as reference layers in a soon-to-be-released web application, and I would love to link to more documentation about (and gain a better understanding of) the "confidence" field. Any pointers on where to look, beyond the official docs? #gischat

#maplibrejs afficionados: Any way around this messy labeling? (numbers 32, 62, and 50) I'm thinking there isn't, as the label layer is on top of the cluster layer, and you can actually see the exact same behavior in the official docs example: maplibre.org/maplibre-gl-...

Thanks to @mradamcox.bsky.social for helping us set this up. Oldinsurancemaps.net is a easy platform for georeferencing with a group, especially those with minimal GIS experience.
