geos VS tippecanoe

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.

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!

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.

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

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.

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.

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.
