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

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?

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.
