osm-liberty-topo VS PMTiles

Most of these examples go up to zoom 10 or so because they cover a wide area. It's not prohibitive to increase that zoom in a small area because the total number of tiles will still be low. Also keep in mind that for vector data it's possible to "overzoom" and allow the client zoom levels to be higher than the physical data levels.

In terms of self hosted maps for outdoors use, I have some open source repos from a few years ago that may help with that. [0] is a style based on the openmaptiles vector tile schema for outdoors purposes. I believe that readme has some overall instructions, plus other repos in the org are for making data. (Nowadays planetiler is probably the best way to make OSM vector tiles though)

I am a novice at GIS and mapping but when I got started I thought a map/tile server was the only way to build mapping webapps.

But, in my admittedly simple application PMTiles can cover a lot of my visualization use cases with a thing Django app doing GEOJson for interactive stuff.

This is awesome. Such a great use case for nix.

I do a lot of geospatial processing in the cloud and I've been using Tippecanoe a lot to create vector tiles. It pairs well with PM Tiles for storing on the cloud. It seriously increases the web app performance for massive data sets. I queue these up with ECS tasks to process our json/csv/parquet input and create optimize vector tile outputs.

Tippecanoe would be a great addition to your nix packages. I've been thinking more and more about how Nix could fit into this pipeline.

Great work!

The thing being discussed is designed for cloud, so I think self managed is a better description?

Self hosting pmtiles is straightforward also, make a file available to a server that supports range requests:

It might've just been this: https://github.com/protomaps/PMTiles/tree/main/serverless/aws

There isn't a tool to do that right now. It could be a fit in either https://github.com/protomaps/go-pmtiles or https://github.com/protomaps/PMTiles/tree/main/python - the Go program is faster and more production ready at this point. I imagine if folders are working for you the quantity of tiles doesn't number into the millions, so the Python program might be sufficient.

Feel free to open an issue.

PMTiles

For the next revision of the JS decoder I'm including `fflate` as a dependency so clients can decompress gzipped tile data using JavaScript.
