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.

Protomaps β 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]

There's a new map style on OpenStreetMap.org
Have been using https://opentopomap.org for this for a while, and depending on what you're looking for it still has some advantages: does show the numbers on all height lines (osm only does the 50m one in my area for some reason, leaving you to guess whether the next one is 40m or 60m since that is not always obvious - seems like a key thing for a topographic map), does show the house numbers.

Are there any good digital atlases?
For example OpenTopoMap looks very similar to most maps that were in my school atlas. I like the MapTiler renderings too.

I need some help creating a map with some layers
https://brouter.damsy.net/ The topo map is provided by https://opentopomap.org/ Alternatively, if you have an OSM account, you can go into edit mode on OSM website and drag GPX traces into the window to display them. You can't get elevation profile this way but you can use topographic map background or a better range of satellite imagery, and you can use Bing imagery without an API key.

Eduard: Swiss-Style Relief Shading for Maps Using Machine Learning
The chances of the problem not having being already tackled with deterministic algorithms is the thinnest - and in fact, yes, there do exist tools, as expected.
See the sections about 'hillshade' at the OpenTopoMap "from scratch" instructions, at https://github.com/der-stefan/OpenTopoMap/blob/master/mapnik...

How to generate MBTiles covering a shape and not a rectangular extent?
I have generated and hosted locally an instance of OpenTopoMap covering South America. Now I want to create a set of MBTiles for each individual country. Using the Raster tools -> Generate XYZ tiles (MBTiles) I can do that for a rectangular extent (drawn on map or calculated from layer). Can I do it for an irregular shape? I downloaded a .shp file for Argentina, for example - https://i.imgur.com/3IGJ88A.png
