In this page they have "space filling curves" as an example in one of the images, but I haven't been able to find production systems that actually use space filling curves for similarity search. Anyone have any tips?
- ashvardanian 3y agoOld-school Postgres extensions for GIS would be an example. They aren’t used much anymore, but I felt like they deserve a place in history :) PS: Love your blog! I have worked on SFCs in the past. Did you?
- j2kun 3y agoI've been looking for good examples for my next book, but everything I've read about has turned out to be not used, including everything in Michael Bader's book [1], except for S2Geometry [2], but I feel like I need to talk to someone who has more expertise in the benefits/drawbacks of using that in an actual product.
