Show HN: Mapping 11M points with Tile38 – Mapbox/Geonames

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&#x27;t remember the name. Thanks for jogging my memory.<p>I&#x27;d love to see a writeup on how you efficiently did this (I&#x27;m assuming protobufs?). I&#x27;m constantly telling one of my clients (gov) that it&#x27;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.

The tile38 docs (<a href="https:&#x2F;&#x2F;github.com&#x2F;tidwall&#x2F;tile38" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;tidwall&#x2F;tile38</a>) are really good.<p>Lots of animated GIFs combined with great structured text that really helps quickly explain all the complex things that a geospatial index can do.

well, points for this<p><pre><code> This package provides an in-memory R-Tree implementation for Go, useful as a spatial data structure.

I&#x27;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?

This is super impressive! Nice work.
