tippecanoe

If your data is already in GeoJSON, you can use tippecanoe to produce a tileset in either MBTiles or PMTiles format: https://github.com/felt/tippecanoe. Or if your data is more dynamic, you can also use the ST_AsMVT extension to query PostGIS, which will generate tiles on-the-fly: https://postgis.net/docs/ST_AsMVT.html

I understand that you probably wanted to implement this from scratch but did you take a look at tippecanoe? https://github.com/felt/tippecanoe originally by mapbox but got forked by felt.

> Static or infrequently updated vector tiles can be generated from OSM data by a number of tools, but those most popular right now are https://github.com/systemed/tilemaker and https://github.com/onthegomap/planetiler this is the first I've seen of these alternative tools compared to using Tippecanoe(https://github.com/felt/tippecanoe). Are they considered to be higher performance?

This is awesome. Such a great use case for nix. I do a lot of geospatial processing in the cloud and I've been using Tippecanoe a lot to create vector tiles. It pairs well with PM Tiles for storing on the cloud. It seriously increases the web app performance for massive data sets. I queue these up with ECS tasks to process our json/csv/parquet input and create optimize vector tile outputs. https://github.com/felt/tippecanoe https://github.com/protomaps/PMTiles Tippecanoe would be a great addition to your nix packages. I've been thinking more and more about how Nix could fit into this pipeline. Great work!

Maplibre[1] + PMTiles + Felt's "tippecanoe"[2] (it can output .pmtiles) are an awesome combination for self-hosted web maps if you're ok with being locked into a Web Mercator projection for pretty much any geospatial source you can convert to .pmtiles via GDAL[3] and tippecanoe (.shp .gpkg ...) | ogr2ogr -> .geojson | tippecanoe -> .pmtiles for OpenStreetMap data there's planetiler[4], and and openmaptiles[5] styles that work with Maplibre with those combinations you've got a great start to something you can host for pennies on AWS S3+CloudFront or Cloudflare R2, with an open source data pipeline [1] https://maplibre.org/ [2] https://github.com/felt/tippecanoe [3] https://gdal.org/ [4] https://github.com/onthegomap/planetiler [5] https://openmaptiles.org/styles/ ps I find GDAL/ogr2ogr documentation pretty hard to parse, as an example to g

Hm. Not totally sure why someone would pay for this - there are lots of readily-available open-source tools that can do this easily. GDAL/OGR[0] and Tippecanoe [1] come to mind. Maybe I'm missing a less-technical audience? 0: https://gdal.org/ 1: https://github.com/felt/tippecanoe

Hi, thanks for the mention! The Mapbox repo has an older version of tippecanoe; there's a newer version actively being improved by Felt at http://github.com/felt/tippecanoe , and they've also funded my addition of the Protomaps format (PMTiles) as a direct output. No conversion step required anymore!

In the tools space, cf. open source GeoJSON-to-vector tile tool Tippecanoe, which recently got a new non-Mapbox home at Felt: https://felt.com/blog/erica-fischer-tippecanoe-at-felt, https://github.com/felt/tippecanoe

I'm the author of a few of the tools mentioned in this post! A convenient new development is instead of using tippecanoe -> go-pmtiles to create PMTiles archives, you can now output .pmtiles directly: tippecanoe -o bks2.pmtiles mainroad.geojson ... This is available in Tippecanoe (https://github.com/felt/tippecanoe) v2.17 and later. Thanks to Felt (https://felt.com) for supporting this open source work.

Take a look at Tippecanoe, which is under active development again[0]. The original developer, Erica Fischer (who is wonderful to work with), has a fork[1] where new work is happening. [0] https://felt.com/blog/erica-fischer-tippecanoe-at-felt [1] https://github.com/felt/tippecanoe
