Pelias Geonames importer

Gitter Build Status Greenkeeper badge

This Node.js package imports data from Geonames into Pelias. It includes utilities for downloading and cleaning up the data before import.

Requirements

  • Node.js '4.0' or greater

Installation

git clone https://github.com/pelias/geonames
cd geonames
npm install

Configuration

The importer can be configured from your local pelias-config (defaults to ~/pelias.json) in the imports.geonames object:

{
    "imports": {
        "geonames": {
            "datapath": "/path/to/geonames/data",
            "countryCode": "MX"
        }
    }
}

The following are all optional:

  • datapath: the path to geonames data. Defaults to a directory inside the importer.
  • countryCode: the two digit (ISO 3166-1 alpha-2) country code for the country for which data will be downloaded and imported. Use ALL for all countries.

Admin Lookup

Pelias has the ability to compute the admin hierarchy (county, region, country, etc) from Who's on First data. For more info on how admin lookup works, see the documentation for pelias/wof-admin-lookup. By default, adminLookup is enabled. To disable, set imports.adminLookup.enabled to false in Pelias config.

Note: Admin lookup requires loading around 5GB of data into memory.
