Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

2024: The year of the OpenStreetMap vector maps
Thanks!
I just browsed the spec again (https://github.com/mapbox/vector-tile-spec/tree/master/2.1) -- I didn't have as bad of a reaction as I did the first time I looked at it.
I guess the idea of using (Google) protobufs for the "packaging" and then a super tight, custom, byte-encoded format for drawing commands seems... weird to me. But, honestly, it probably makes sense.

From Vector Tiles to LON/LAT?
Read the vector tile specification at https://docs.mapbox.com/vector-tiles/specification/ and https://github.com/mapbox/vector-tile-spec/tree/master/2.1 . The values you're seeing from zero to 4098 are relative to the extents of a given tile. Note the tile extents can vary between implementations.

2024: The year of the OpenStreetMap vector maps
Have a look at https://www.serverlessmaps.com/ which uses PMTiles to generate the tiles from OSM data. It's also possible to host the PMTiles directly on S3 and use HTTP range requests to retrieve the desired bounding boxes. Under the hood, it uses CloudFront as CDN, Lambda@Edge functions and S3 (see architecture at https://github.com/serverlessmaps/serverlessmaps/#architectu...)
It's a very cost-effective solution as CloudFront has a 1TB/Month free tier, compared to hosted solutions.

Protomaps – A free and open source map of the world
We've had quite some success with deploying "serverless" maps, leveraging PMTiles. Have a look at https://github.com/serverlessmaps/serverlessmaps if you're interested to deploy this on AWS CloudFront/Lambda@Edge/S3...
