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.

Serverless maps at 1/700 the cost of Google Maps API
Hi, the value add in the commercial offering is described here:
https://protomaps.com/docs/faq#openstreetmap
I also maintain open source tooling for anyone to replicate and consume all of OSM, as well as a free download portal:

Why OSM doesn't use PostgreSQL for replication?
I work a lot with OSM data, and never loaded into PostgreSql… On one project I keep data in https://github.com/protomaps/OSMExpress, another I keep it in .pbf and just handle minutely changes in memory, then even for PostgreSql there are multiple schema tables each optimized for different work, render server schema is very different from API server…

Best practice for PBF filtering?
You did not specify what kind of filtering you want to do, but if you are after area extracts like whole cities or similar, best thing is OSMExpress unfortunatly it takes long time to initialize it for whole planet, but after that extracts are done in seconds.

Protomaps - a new way to make maps with Openstreetpap
The major open source component that runs on the server (https://github.com/protomaps/OSMExpress) is tricky to package because it depends on S2 Geometry, which itself has some tough dependencies; the users I know out there are compiling it themselves, or using the community-contributed Dockerfile. I would prefer a .deb, do you think a PPA is the right approach?

Protomaps – A free and open source map of the world
(.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

New Map APIs from Google
Does anyone else have a solution for the satellite layer? I was using MapLibre [0] then needed direct-on-the-ground images which made me convert to Google Maps.

Use 3D map library with API key function of Amazon Location Service
When using the Amazon Location Service, I recommend MapLibre GL JS, which I introduced in my previous article, "Amazon Location Service and AWS Amplify to Use Various Map Library," but you can also use any map library you like, including iTowns this time. I hope you will choose the map library of your choice, including iTowns!

Using Lidar to map tree shadows
Your browser has a very powerful image decoder built into it, offloading the PNG decoding into Javascript is very resource hungry.
Using maplibre (or any map viewer) you can load blobs of image data out of a tiff and use `Image` or `Canvas` to render the data onto a map.
Its even easier if the tiffs are already Cloud optimized as they perfectly align to a 1-to-1 map tile and they don't need to be rescaled, you can then just render the images onto the map. eg here is a viewer that loads webps out of a 15GB tiff and uses Canvas to render them onto a map [1]
Unless you are trying to layer all your maps together, you also could stop reprojecting them into webmercator, or if your goal is to layer them, then storing them in webmercator would save a ton of user's compute time.
There are a bunch of us that talk web maping and imagery in the #maplibre and #imagery slack channels in OSMUS's slack [2]
