What does naturalearth have that OSM doesn't? I checked the site and it's showing what looks like a subset of OSM

Natural Earth is generalized (low zoom) data and has hand-curated scaleranks on features to determine what features appear at low zooms. None of that is in OSM.

Ah, thanks!

It depends what you use it for. I plan to use it for blog posts where I show the track of where I walked. I actually like that the map won't update. It wouldn't make sense to show me walking across a map of the future, would it? It's a record of the past and the map should be frozen just like the writing.

Sure, but in GP's context of local businesses, they certainly will want to keep up-to-date with any changes to make sure customers can still find them.

Yes, absolutely. I think, in that case, a managed tileserver (using PMTiles or otherwise) is probably the best solution.

If anyone else was curious, their sample OSM derived PMTile file (protomaps-basemap-opensource-20230408.pmtiles) is 103GB. https://docs.protomaps.com/basemaps/downloads

What are they using to compress tiles? Could they get even smaller with AVIF? Or AVIF+SVG overlaid for text?

Cool but basemaps are a very tricky thing from a geographers perspective. There are several border conflicts. When it is open source there could be some manipulation. Immediatelly getting downvoted. All I'm saying is that official map boundaries these days should be used. Because I can again not post because too fast here my clarification: I mean official not commercial or proprietary

This is so true. Otherwise all Mapping authorities would be useless. I could change my house ground area and nobody cares

We actively use this at Street Art Cities (https://streetartcities.com). Really helped keep hosting costs down for a project that is more community than commercial, and created a more cohesive experience.

For all who downvotes. Here is the prof that leaving Mapping borders open source is not the way: https://www.calcalistech.com/ctechnews/article/r1hyeammt

I'm a student trying to upskill in geospatial/compsci. What kinds of projects could you make with all of this? Any good starting points you'd recommend?

Not OP, but almost anything where "a map" is the output will be a hugely big learning opportunity for you. Static maps, print-quality maps, interactive web maps -- the experience of building any of those will bring lots of learning. (That's how I got started.)
