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.

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

Zooming User Interface (ZUI)
You probably know this, but in Google Maps at least, you can use browser zoom (ctrl/cmd +/-) to change the size of labels without zooming into the actual map.
------
Speaking of maps, I got to work a fun zoom project a few years ago: https://map.fieldmuseum.org/
We used https://openlayers.org/ and thought long and hard about how to best handle zooming and variable levels of information density & visual hierarchy. If you zoom all the way out, we just highlight where the building is relative to the surroundings. As you start to zoom in, we start to highlight major exhibitions and entrances. Then as you zoom in more, we start showing recommended paths, smaller exhibitions, etc. The label sizes try to scale up and down at each level, smoothly, in order to balance readability and density.
Eventually you can reach the max zoom level and the labels will just grow bigger and bigger, but the SVGs dynamically shrink so they remain pictograms and not just contextless-lines.
Then if you keep going, you eventually find microscopic easter eggs :)
The code is pretty jank (and abandoned), but it's FOSS vanilla JS/HTML/CSS, and the only dependency is on OpenLayers: https://github.com/arcataroger/openlayers_indoor_map

Handling files in enterprise web solutions
In order to display the GeoJSON features on a map, we will use OpenLayers, which is a very powerful open-source mapping library that is also very simple to use.

5 JavaScript mapping APIs compared
OpenLayers is available via the ol npm package, offering developers a powerful toolkit for creating sophisticated maps. Here is a JavaScript implementation that utilizes OpenLayers to showcase a map:

I'm a senior in my CS major and it's incredible I didn't hear about GIS projects until now. Glad to be here.
For web maps I'd strongly recommend using OpenLayers. While it's less convenient to get started with compared to the alternatives it's also much more feature-complete and you'll likely hit a ceiling in terms of functionality much later than you would with the others.
