VapourTrail is an interactive bus map made from OpenStreetMap data.

VapourTrail aims to be a large scale or local solution for visualizing bus lines from OpenStreetMap data.

Vapour Trail is made of:

• a tileset of map vector tiles
• an API to query bus routes and stops
• a web front-end that turns the tiles and API into an interactive map

How to run

You will need docker and docker-compose.

• Grab some OSM data (in .osm.pbf format) and put the file into the imposm/import/ directory
• Start the services with make run
• Import or update the OSM data with make update-data

You can then browse your interactive map at http://localhost:8082/

Troubleshooting:

If you have performance issues, you may want to pre-generate the tiles before using the front-end : make generate-tiles bbox=minlon,minlat,maxlon,maxlat

Deploy a static version

If you are on a small area or network, you can create and use a static version (that can work without its database, tile server and API):

• start the services with make run
• import data: make update-data
• generate tiles for your area of interest: make generate-tiles bbox=minlon,minlat,maxlon,maxlat
• prepare static publication: make prepare-static static_url=http://localhost/
• you can now deploy and serve the static folder

Contribute

Behind the scenes, Vapour Trail uses

• postgre / postgis
• imposm3
• t-rex
• python3 with flask and SQLAlchemy

The API is available at http://localhost:5000.

The tiles rendered by t-rex are available at http://localhost:6767/.

Style Edition

The displayed map used bus vector tiles served by the t-rex server and Jawg vector tiles with a custom theme for the background style.

While the t-rex tiles server is running you can upload glstyle.json to the online Maputnik Editor, make your changes and export it back to the project.
