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.

Geospatial Nix – create, use and deploy today
https://libgeos.org/
GEOS is a C/C++ library for computational geometry with a focus on algorithms used in geographic information systems (GIS) software. It implements the OGC Simple Features geometry model and provides all the spatial functions in that standard as well as many others. GEOS is a core dependency of PostGIS, QGIS, GDAL, Shapely and many others. -
Share Your Code.. Share your most unique piece of Go code.
It has the same purpose as [libgeos](https://libgeos.org/) but is implemented in Go rather than in C/C++. The primary use case is to reduce CGO dependencies while working with Go!

Serverless maps at 1/700 the cost of Google Maps API
If you have any geospatial data, you can tile it with tippecanoe [0], which gives you an mbtiles file. Protomaps lets you easily convert the mbtiles file into a protomaps file which you can then use.
Protomaps doesn’t limit you to any particular type of tiles, it’s just a format which allows you to read tiles out of a single file with HTTP range requests.

How would you generalize a very high density vector map for various zoom levels ?
or you can build several geojson add the zoom level at feature with their extension and then merge into one geojson. https://github.com/mapbox/tippecanoe

Reducing vector tile size in QGIS for Mapbox import
Unsure how to do it with qgis. however it seems to be simple with Tippecanoe..here. They seem to have some examples that show what you need to do in the readme.

Why do I need geoserver?
For my work when I asked that question, I had all vector data -- about 10gb -- and I used a combination of geojson's and vector tiles that I made using mapbox's tippecanoe.

A new way to make maps with OpenStreetMap
Author here, so there are a few options:
1) If your information belongs in OpenStreetMap, you can add it via an editor like the web editor at https://openstreetmap.org - this will also benefit all other OSM users. You can then "refresh" your Protomaps download to get a new map.
2) If there isn't many point and polygons, it may sense to add them as Leaflet layers, especially if you want them to be interactive
3) Other options are creating vector tiles of your own data and merging or displaying them in the renderer (https://github.com/mapbox/tippecanoe is a great tool to do this from GeoJSON) but I don't have much to support this yet.
What are some alternatives?
gdal - GDAL is an open source MIT licensed translator library for raster and vector geospatial data formats.
tilemaker - Make OpenStreetMap vector tiles without the stack
go-c2dmc - A Go package for converting RGB and other color formats/colorspaces into DMC thread colors (DMC color name and floss number)
