Show HN: Mapping 11M points with Tile38 – Mapbox/Geonames
- voltagex_ 8y agoThis is super impressive. Do you have a write up on the datasets used and the process you went through?
- spectre256 8y agoThe tile38 docs (https://github.com/tidwall/tile38 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.
- tidwall 8y agoThanks :)
- mistrial9 8y agowell, 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.

- atonse 8y agoI 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.
- ptrott2017 8y agoI 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.
- atonse 8y agoGood to hear! I’ll definitely play with it when I have some free time.
- nouney 8y agoI've been using Tile38 for over a year now. It is amazing.
- tinfoilboy 8y agoThis is super impressive! Nice work.
