README

mapzen_odes

What does it do?

Downloads the latest planet in pbf format. Produces, via osmconvert, a number of metro extracts in both pbf and bz2 formats. Produces shape files in both imposm and osm2pgsql formats.

Projections

GeoJSON is generated via ogr2ogr and output in CRS:84 (e.g. EPSG:4326) projection.

Imposm shapfiles are generated in EPSG:4326.

What hardware do I need?

An m4.4xlarge is a good starting point, anything bigger will make things faster. About 300gb of storage for the planet file and all the extracts you plan to generate, plus Postgres (if you run it locally… you can use something like RDS as well).

Supported Platforms

Tested and supported on the following platforms:

• Ubuntu 14.04LTS

Requirements

• Chef >= 11.4

Usage

Run the recipe mapzen_odes::default, and pass custom json in the node[:mapzen_odes][:json] attribute containing a list of cities and bbox's. The city name is arbitrary but will be used to name output files, so ensure they're unique in a given run. You can then pass boolean values to any of the process attributes to include (or not) the output they handle.

Expected json blob sample:

'mapzen_odes': {
  'upload_data': true,
  'json': {
    'cities': {
      'some_city': {
        'bbox': {
          'top': 'bbox_n',
          'left': 'bbox_w',
          'bottom': 'bbox_s',
          'right': 'bbox_e'
        },
        'process': {
          'imposm_shapes': true,
          'xml_extracts': true,
          'coastlines': true,
          'imposm_geojson': true
        }
      }
    }
  }
}
