Well, nice try, but sadly maintaining up to date GIS data takes much more than a UI. The only thing that gets close to such datalake is perhaps OSM and ESRI World Atlas... but nothing is close to huggingface or github as positioning. Besides, data is a live thing, and all such cartography very quickly dates and gets irrelevant or incorrect.

Looks like you missed that MapComplete is an alternative interface to view OSM data and contribute to it.
