Open Sea Map Vector Tiles

Infrastructure to generate vector tiles for OpenSeaMap .

Run Workflow

The entire project is structured in components using Docker containers to work together. Ensure you meet the prerequisites.

Please note that after changing the configuration files you need to rebuild the containers. See below for relevant configuration files.

Example: docker-compose build import-osm

Setup

• Install Docker
• Install Docker Compose

Start up the PostgreSQL database with the PostGIS extension.

docker-compose up -d postgres

Import the required database schema (views, prepared tables and helper functions).

docker-compose run db-schema

OSM Import

Now download a OSM PBF extract and store it in the ./data dir. Import the OSM PBF.

docker-compose run import-osm

Note: The mapping.yml determines which tables will be filled with which nodes and tags.

The mapping syntax is documented here.

Setup export options

To visualize and work with the vector tiles you can spin up Mapbox Studio in a Docker container and visit localhost:3000.

Then open the vector tile source with Browse and choose from /projects/vector-datasource.tm2source.

docker-compose up mapbox-studio

Edit the source settings by adding layers and using SQL queries to fetch data from the tables created by the OSM Import step.

This will modify the vector-datasource.tm2source file.

Export the vector tiles

Export the vector tiles for the planet.

docker-compose run export-vectortiles

Note: The file export-mbtiles.sh determines the options for the export. Change the bbox according to your data.

Serve the vector tiles

Use klokantech/tileserver-gl to serve the tiles.

docker-compose up serve

Visit localhost:8080.

Export the data as GeoJson

Exports the data as GeoJson

docker-compose run export-geojson

Note: The file export-geojson.sh determines the options for the export.

The data can be upload in Mapbox Studio to allow creating of styles using their tools. See the OSM2VectorTiles doc for details.
