If you would like to run this comparison for tileservers reading from disk, I wrote a small tool to simulate traffic based on access logs of OpenStreetMap tiles: https://github.com…

Thanks for giving it a try! If you're going to revisit this, we could improve the docs around setting CORS configuration on DigitalOcean: https://docs.protomaps.com/pmtiles/cloud-s…

I don't have any insight into this other than observing how their storage system works, but here's some scripts I made last year to test: https://github.com/bdon/cloudflare-r2-late…

You can test this claim directly against a AWS S3 bucket. First 100KB of a 100GB+ file: curl -H "Range: bytes=0-100000" https://overturemaps-tiles-us-west-2-beta.s3.amazonaws.com/2…

I see, I think that's a good approach to enable serving with stock nginx as well as for companies that are built on Nginx or a plain HTTP serving stack already. For PMTiles the mod…

OMT use a CC-BY license: https://creativecommons.org/faq/#can-i-apply-a-creative-comm... (edit: link) This means that software that implements OMT, even if written from scratch, ca…

I agree, there are tradeoffs to using static storage - the intended audience for PMTiles is those that prefer using static sites instead of administering a Linux server. I would be…

The latency for small files and ranges of large files is pretty similar on most storage platforms, but there are some exceptions like Cloudflare R2. The main reason PMTiles is one …

1) The Protomaps schema is mostly a re-implementation of the Tilezen project https://tilezen.readthedocs.io/en/latest/ which is a linux foundation project. OpenMapTiles, which Open…

I'm the developer of Protomaps, to summarize: The latency you see on https://pmtiles.io/?url=https%3A%2F%2Fdata.source.coop%2Fpro... is representative of how PMTiles works on AWS S…

Here's an example of the entire planet as a PMTiles: https://pmtiles.io/?url=https%3A%2F%2Fdata.source.coop%2Fpro... This is zoom 0-15, or 1,431,655,765 addressed tiles. So it is d…

To mitigate the "denial of wallet" attack on S3 there are a few options: AWS Lambda: https://docs.protomaps.com/deploy/aws lightweight tile server: https://docs.protomaps.com/pmtil…

The replacement for the UI is to use the "pmtiles extract" command line tool: https://docs.protomaps.com/guide/getting-started#_3-extract-...

I maintain a small MVT rendering library for Leaflet - I'm overall satisfied with the performance on modern devices, but usually point greenfield projects at MapLibre instead, unle…

There is nothing stopping the OSM Foundation from say, offering a complete SQLite (or PMTiles) tileset download on planet.openstreetmap.org, technically, legally or otherwise. Crea…

Leaflet is a separate project from OpenStreetMap - it's just one popular frontend for viewing tiles served from openstreetmap.org, like OpenLayers. I don't believe the OSM Foundati…

It doesn't, pmtiles is designed for tilesets updated at a daily to quarterly frequency, by replacing the entire archive on cloud storage. for minute-level updates serving tiles out…

Most of the development for pmtiles has happened in the last 2 years, including a maturing server implementation ( http://github.com/protomaps/go-pmtiles ) but some key parts are s…

Natural Earth is generalized (low zoom) data and has hand-curated scaleranks on features to determine what features appear at low zooms. None of that is in OSM.
