openmaptiles VS headway

Openmaptiles uses docker-compose for its work. It fails flat on its face with podman.

OpenMapTiles

What is the advantage of this project over something like openmaptiles https://github.com/openmaptiles/openmaptiles

Flatmap calls into user-defined profiles in 2 places: first when processing each input element to map it to a vector tile feature, then a second time right before emitting all vector features in a layer.

That second call lets you manipulate vector features on each tile using JTS geometry utilities (i.e. merge nearby polygons or lines with the same tags). PostGIS uses GEOS which is ported from JTS so you have access to pretty much the same geometry utilities - often with the same name.

It's definitely not as flexible as a PostGIS based solution - especially if you join faraway features that don't appear on the same tile, but in practice it was enough to port the entire OpenMapTiles schema.

See the basemap layers package: https://github.com/onthegomap/flatmap/tree/main/flatmap-base...

For example see the landcover layer: https://github.com/onthegomap/flatmap/blob/main/flatmap-base...

Which was ported from the SQL contained in: https://github.com/openmaptiles/openmaptiles/tree/master/lay...

Also, this OpenMapTiles PR might help improve your pipeline after it gets merged: https://github.com/openmaptiles/openmaptiles-tools/pull/383

To fully self-host a route planner (e.g. a "Google Maps" equivalent) you need GraphHopper for the routing and two other parts: you also need some visualization aka "maps" (e.g. with OpenMapTiles) and you need the address search (e.g. with Photon).

Probably not the answer you're looking for, but I have been using openmaptiles to pull osm into postgres (in docker using quickstart.sh). If you can talk postgres in python then maybe that is for you?

You might want to peek at https://github.com/headwaymaps/headway . I have never used it myself, but it at least shows how to integrate the different pieces.

The individual software components often have alternative with a similar scope. So if you don't like a choice headwaymaps made, browse around.

The data sources are mostly "unique", i.e. everybody downloads from the pages (Geofabrik, Who's On First, etc), so not much to gain here.

Editing styles has some alternatives, but the OpenSource editors are far away from the quality of the Mapbox editor. Maputnik or editing the 1000+ SLOC JSON by hand are the way to go, imo.

Personally I use GeoFabrik to download OSM extracts → osmconvert to extract the smaller bounding box I am interested in → tilemaker to render vector tiles to individual .pbf files I can serve like it's 1999. The bounding box extract is not necessary, but it's much faster if you need to tweak things in tilemaker. Both tilemaker and osmconvert are packaged for at least Debian out of the box, so setup is easy enough. Rendering a decently sized metro area takes < 30mins with this from scratch of compute, < 5min with the bounding box extract.

Note that adding icons (sprites) or fonts is extra work that comes on top. And while the tools themselves are great, there's still a lot of gluing/plumbing/fitting things together that you'll need to do. If headwaymaps works for you, it's probably the easiest choice.

In a similar vain, there is maps.earth / headway:

Another self hostable OSM stack that seems promising is headway
