[Talk-us] OpenStreetMap Americana - Announcing a new American map style and call for collaborators!

[Brian M. Sperlongano]

Hi Greg - thanks for this question!  It is 100% possible to recreate this
locally or on your own servers via pure FOSS, and especially easy if you
only want a small area rendered.  MapTiler Cloud is simply a convenient
service that serves OpenMapTiles-compatible vector tiles for the planet,
and saves us from having to do a fairly resource-intensive planet render.
The downside is that it's not updated terribly frequently, and there is a
usage limit for their free tier, but it's something I hope that OSMUS can
address in the future.  Here's a set of steps that would get you up and
running on an openstreetmap-americana rendering of Massachusetts for
example:

1. Clone the OpenMapTiles repository (
https://github.com/openmaptiles/openmaptiles) and build an mbtiles for
Massachusetts with the command: ./quickstart.sh massachusetts.  This will
produces a tiles.mbtiles file in the folder data/
2. Run: make start-tileserver.  This will start a vector server on
localhost:8080
3. Clone the openstreetmap-americana repository (
https://github.com/ZeLonewolf/openstreetmap-americana)
4. Copy the config.default.js to config.js, and change the URL to point to
the tile server, by default this is: http://localhost:8080/data/v3.json
5. Run: make run.  This will pop open a web browser on localhost:1776
running the style.
