I was having a conversation with a coworker and was looking for exactly what Tile38 is, telling them the amazing kinds of realtime-GIS things available out there, and I remember seeing this a while back but didn't remember the name. Thanks for jogging my memory.

I'd love to see a writeup on how you efficiently did this (I'm assuming protobufs?). I'm constantly telling one of my clients (gov) that it's no longer a big deal to show even 10,000 points on a map thanks to Mapbox GL etc in a performant way, without relying on GeoJSON. Now I can show this proof of concept.

I have used Tile38 for a couple of internal demo experiments this year and hoping to push the projects into production next year (budget allowing).

If you are looking for a realtime-GIS with geofencing support out of the box - it is an ideal match.

Docs really are great. Its very easy to get quick demos up and use. The code base is a joy to work with. It is a really really good project.

Would also love to see a write up of the 11 million points with Tile 38 - that is a really nice demo.

Good to hear! I’ll definitely play with it when I have some free time.

The tile38 docs (https://github.com/tidwall/tile38) are really good.

Lots of animated GIFs combined with great structured text that really helps quickly explain all the complex things that a geospatial index can do.

Thanks :)

well, points for this

  This package provides an in-memory R-Tree implementation for Go, useful as a 
  spatial data structure.
  It has support for 1-20 dimensions, and can store and search multidimensions 
  interchangably in the same tree.

I've been using Tile38 for over a year now. It is amazing.

This is super impressive. Do you have a write up on the datasets used and the process you went through?

Thanks. It was a team effort. We’re working on a medium article. The dataset is Geonames.

Can't wait to read this. Well done

This is super impressive! Nice work.
