I wish it wasn't Mapillary.. I know it's the most popular but still.
OpenStreetMap community
Everything #OpenStreetMap related is welcome: software releases, showing of your work, questions about how to tag something, as long as it has to do with OpenStreetMap or OpenStreetMap-related software.
OpenStreetMap is a map of the world, created by people like you and free to use under an open license.
Join OpenStreetMap and start mapping: https://www.openstreetmap.org/.
There are many communication channels about OSM, many organized around a certain country or region. Discover them on https://openstreetmap.community/
https://mapcomplete.org/ is an easy-to-use website to view, edit and add points (such as shops, restaurants and others)
https://learnosm.org/en/ has a lot of information for beginners too.
Hm? What's wrong with them?
They're owned by Meta.
Ah, didn't know that. Then yeah, fuck Meta for taking advantage of crowdsourced efforts
Openstreetmap is copyleft so it isn't quite so bad
Would Panoramax be your preference? It seems like it just needs some more global instances? Federation with AP using https://github.com/swicg/geosocial would be really neat for these types of projects too.
While decentralized is great, I wish Wikimedia would start something similar, maybe with the data still hosted in WikiCommons?
