24 alternatives to Geometry-aware Hashing of GeoJSON objects
Just a quick little feature I implemented over the weekend. TODO: Assure that polygons can be palindromic as well
Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Geometry-aware Hashing of GeoJSON objects launched in 2024; newer entries below may have overtaken it.

Long-simmering side project that is finally ready to see the light. HAMTs are a cool persistent data structure and implementing one has been a lot of fun. Beyond the code, there is likely some value in the extensive and largely complete implementation docs; basic benchmarks are linked in the README, too. Kind of aiming to be "the libavl for HAMTs". That is obviously a high and aspirational bar but a distinct possibility if it stirs up a little interest and/or contribution. Anyways, it's time for this to go out, collect feedback and maybe even some use outside of toy projects. Let me…

My friend and I have been collaborating on this lighthearted introduction to doing geospatial computation in rust. Don't know Rust? Don't know geospatial? I'd be interested to know what you think.

I've recently been working with real-time geoJSON data at a rate of 50+ queries per second. SaaS solutions can be prohibitively expensive at this rate, thus, I created go-reverse-geo. Data is pulled from geonames.org and is stored in MongoDB (a requirement of my current project). It is very much a work-in-progress (I wrote it this morning). Hope someone finds it useful. https://paranoia.dev/vivi/go-reverse-geo

Frustrated by the inability to play with semantic search / ANN in Go w/o a heavy-weight external DB, I created this HNSW library. I hope other gophers find it useful.
