CreateVectorTiles Task

A GBDX task to create vector tiles from any valid OGR datasource.

Building Docker Image

  1. Create a .gitconfig file in the main directory with valid username and password credentials

    This is required in order to clone tippecanoe as part of the build process.

  2. docker build -t create-vector-tiles:<version> -t create-vector-tiles:latest .

Testing

  1. Place your test data in test-mnt/input/data. Input datasets can be in any valid OGR format (have not tested this thoroughly). Multi-file formats should be in a single directory within test-mnt/input/data.

  2. Create ports.json file in test-mnt/input (see test-mnt/input/ports.template.json as an example).

  3. docker-compose up test

Task definition

@saintsjd Let me know what you think about this signature for the vector tiles task (I'm open to suggestions).

My general thought was to use Python to orchestrate the task. Within that we could:

  • use subprocess to call ogr2ogr to convert the input sources to GeoJSON
  • validate the tippecanoe options
  • call tippecanoe
  • use mbutil to create the tile structure if that option is passed in, otherwise just save out the .mbtiles file
