baremaps / openstreetmap-vecto

General purpose vector tiles and vector style based on OpenStreetMap.

OpenStreetMap Vecto

🚧 🚧 The development of openstreetmap-vecto moved to the Baremaps repository. 🚧 🚧

OpenStreetMap Vecto is a general-purpose configuration for Baremaps. It is used to generate vector tiles and to produce a Mapbox style inspired by OpenStreetMap Carto.

Requirements

• Postgres 13+
• PostGIS 3+
• Java 17+
• Baremaps 0.7+

The database should be accessible with the following jdbc settings:

jdbc:postgresql://localhost:5432/baremaps?user=baremaps&password=baremaps

Getting started

In order to experiment with OpenStreetMap Vecto, you first need to clone the current repository

git clone [e-mail]:baremaps/openstreetmap-vecto.git
cd openstreetmap-vecto/

Assuming that the necessary requirements have been installed, the database can be populated with the following command.

baremaps workflow execute --file workflow.json

The development server can be started with the following command.

baremaps map dev --log-level DEBUG \
  --database 'jdbc:postgresql://localhost:5432/baremaps?user=baremaps&password=baremaps' \
  --tileset 'tileset.json' \
  --style 'style.json'

Editing the tileset

The configuration format used in the tileset.json file extends the TileJSON specification. Simply put, it adds in the ability to describe the vector_tiles and their content with SQL queries that follow the Postgis dialect.

{
  "tilejson": "2.2.0",
  "tiles": [
    "http://localhost:9000/tiles/{z}/{x}/{y}.mvt"
  ],
  "vector_layers": [
    {
      "id": "aerialway",
      "queries": [
        {
          "minzoom": 14,
          "maxzoom": 20,
          "sql": "SELECT id, tags, geom FROM osm_ways_z${zoom} WHERE tags ? 'aerialway'"
        }
      ]
    }
  ]
}

Editing the style

The configuration format used in the style.json follows the Mapbox style specification. Baremaps integrates Maputnik and most of the modifications will take place in the browser.
