tilemaker VS PMTiles

You can download an extract of your country from Geofabrik, run it through Tilemaker (https://github.com/systemed/tilemaker) to get a nice mbtiles file, and then use the built-in Ruby server to give you something you can load in your web-browser locally.

I ran into this solution last week on HN and decided to give it a try. The pipeline that got me up and running was geofabrik osm.pbf[0] downloads, pass those into tilemaker[1] to create mbtiles, and then pass those into pmtiles[2] to make the pmtiles.

Tilemaker

If you do vector tiles instead of raster, you could use tilemaker: https://github.com/systemed/tilemaker

Try to convert by GDAL files from geofabrik, ogr2ogr make my laptop hurt, but not tiles. Found tilemaker, looks better, but i get only markers, not images.

MBTiles is also a format that is supported more and more, something like tilemaker can help you with that. https://github.com/systemed/tilemaker

I'm trying to build offline maps for my app and I've figured out the app part. Now all thats left is getting the MBTiles file for all regions of the world and host it on my own somewhere. I tried to generate these files myself using [tilemaker](https://github.com/systemed/tilemaker) but I soon realised that with my limited computing power it would take forever to process 50GB worth of files for the entire planet.

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.
