Graphhopper VS PMTiles

Well I think what he means is that we dropped the explicit support of Android and the example app with offline maps (Mapsforge), see this issue: https://github.com/graphhopper/graphhopper/issues/1940

But offline routing should still work on Android. But as you need JDK 1.8 support this will exclude a few older Android versions and devices, I think.

Graphhopper. It has an Android client that uses its web service. You can also try out the web app.

This is now fixed and deployed. See the route here and the specific fixed examples here. Note that you can still find the dangerous spots via clicking the "stop" icon below the route information multiple times. But this is likely a result of the bad cycling infrastruture as cycle.travel contains these short dangerous parts too and if you do such longer routes for Germany it does not happen.

I'd suggest refactoring to use a self hosted version of Graphhopper (https://www.graphhopper.com/open-source/ - they have a docker image you can use and pass in an OSM file to build a graph on) or OpenRouteService to limit your cost exposure to google.

Open Source. The routing server is open source too and geocoding too.

Valhalla is great (I've contributed a few patches and run it for a while)!

if you attached a geolocation to each meeting that should be possible. either using the google maps API or a self-hosted graphHopper instance

I just improved the documentation for the map matching a bit. Maybe this also helps a bit.

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.
