While useful, this still uses a server to process tile requests. Why not https://github.com/protomaps/PMTiles ? For the record, I am currently using maptiler over at https://citybik.es to serve tiles, and I am evaluating moving to serving static pmtiles on range requests to cut the middle man
I’ve been thinking of making a native map and globe program similar to Google earth to embed inside a dashboard (visually similar to kerbal space program).
So far I was thinking about just using ArcGIS (or something else) and taking in free Lidar data and imposing the depth to satellite or OSM tiles then rendering them as OBJs in OpenGL (or maybe a full 3d engine like unity). This unfortunately wouldn’t be an automatic process as lidar data is taxing to process in real time, especially for a SBC.
I do see that there are some 3D tiles sets out there but I don’t see where I can pull them from nor how it compares to the lidar data.
However, the main goal is a 3D terrain viewer in an offline native program.

Hosting maps of the entire planet in a single file doesn't seem practical. How do you keep it updated? PMTiles is good for small local maps, but I don't think they're meant for this scale.

This is zoom 0-15, or 1,431,655,765 addressed tiles. So it is designed for this scale - for a production internet site you can add a lambda, server or CDN as an additional layer for lower latency: https://docs.protomaps.com/deploy/
Does anyone know if there is a way to host just a few of the tiles in a static way? For example, if I wanted to build a web page which just shows a map at zoom level 6 for a lat/lng point, and then go to zoom level 13. That would require a tiny subset of tiles; is there a simple way to add the tiles plus the JS code in a static way so no external downloads were necessary?

Tangentially related, does anyone know of an open source 3D terrain system?

You can get the heightmap from NASA. It's 10x10 meter resolution, which is enough for static geography.

You can simply pre-render them and store the png tiles in a folder. The folder structure and naming has to be such that e.g. leaflet understands it. Did this for a research demo here: https://map2seq.schumann.pub/nllni/demo/
Is there actually a simple way to pre-render? AFAIK it's a lot of work and learning at least if you're coming from scratch.

I've always wondered why people keep adding the s. Is it marketing because Google Map sounds like a spelling mistake (missing 's after Google) and we're noticing the effect of that other brand, or is there something about OpenStreetMap that makes it seem like a plural project? People don't say Linuxes, Signals, or Androids
I think it's most likely that most of the other commonly used alternatives (most significantly Google Maps but also Apple Maps, Bing Maps, Maps.me) use the plural.

Yeah going to full 20 requires about 2TB iirc, OSM doesn't host beyond level 19 anymore either to reduce traffic. 14 is around 10m per pixel, best you'll be able to make out on that is like a street. Not useful enough to bother with imho, even 19 leaves a lot to be desired up close. https://wiki.openstreetmap.org/wiki/Zoom_levels
Worth noting that these are vector tiles and not raster tiles, so zoom levels work slightly differently. Generally you don't need as high zoom level with vector tiles since it is much easier to 'zoom in' on vector data than on raster data. A vector zoom level of 14 stores the data with roughly 50cm precision which is good enough for most casual mapping uses.
Hosting those is super simple. The problem I have is how to generate them efficently w/o big resources.
