PMTiles VS OSMExpress

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.

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

Hi, the value add in the commercial offering is described here:

https://protomaps.com/docs/faq#openstreetmap

I also maintain open source tooling for anyone to replicate and consume all of OSM, as well as a free download portal:

https://github.com/protomaps/OSMExpress

https://app.protomaps.com/downloads

I work a lot with OSM data, and never loaded into PostgreSql… On one project I keep data in https://github.com/protomaps/OSMExpress, another I keep it in .pbf and just handle minutely changes in memory, then even for PostgreSql there are multiple schema tables each optimized for different work, render server schema is very different from API server…

You did not specify what kind of filtering you want to do, but if you are after area extracts like whole cities or similar, best thing is OSMExpress unfortunatly it takes long time to initialize it for whole planet, but after that extracts are done in seconds.

The major open source component that runs on the server (https://github.com/protomaps/OSMExpress) is tricky to package because it depends on S2 Geometry, which itself has some tough dependencies; the users I know out there are compiling it themselves, or using the community-contributed Dockerfile. I would prefer a .deb, do you think a PPA is the right approach?
