Command line, config file documentation/tutorial?

[jatech1]

Is there any place to find documentation or info on the new geojson support and how to add a geojson layer to existing OSM build, or do completely new build with multiple geojson layers only? Also, any good examples of how to go further and control specific layer settings like min/max zoom levels, included/excluded properties, etc. with teh yaml config file? Is there a sample yaml file that matches the default full world build of the example command line that could be used as a starting point to add/modify? Thanks!

You can add a geojson source to a java profile with something like:

Planetiler.create(args)
  setProfile(profile)
  .addGeoJsonSource("mygeojson", Path.of("path", "to", "file.json"))
  .run()

Then in your profile's processFeature method you'll get source features where source name="mygeojson" and layer="file" (file name without extension) that you can process just like if they had come from any other source like osm.

In yaml, you can add a geojson source:

sources:
  mygeojson:
    type: geojson
    local_path: "path/to/file.json"

then use it in a layer definition:

layers:
- id: water
  features:
  - source: mygeojson
    geometry: polygon
    include_when:
      natural: water
    attributes:
    - key: natural
    - key: intermittent

The default openmaptiles profile is too complex for yaml config so is implemented in Java in https://github.com/openmaptiles/planetiler-openmaptiles. There's not currently a way to combine a java profile and yaml in a single run, so for now you'll need to produce 2 separate mbtiles/pmtiles files.
