Pelias OpenAddresses importer

Greenkeeper badge

This repository is part of the Pelias project. Pelias is an open-source, open-data geocoder built by Mapzen that also powers Mapzen Search. Our official user documentation is here. Build Status


The OpenAddresses importer is used to process data from OpenAddresses for import into the Pelias geocoder.


Node.js 4 or higher is required.


git clone
cd openaddresses
npm install

Data Download

Use the imports.openaddresses.files configuration option to limit the download to just the OpenAddresses files of interest. Refer to the OpenAddresses data listing for file names.

see the 'Configuration' section below for a more detailed example of how to use imports.openaddresses.files

npm run download


# show full command line options 
node import.js --help
# run an import 
npm start

Admin Lookup

OpenAddresses records do not contain information about which city, state (or other region like province), or country that they belong to. Pelias has the ability to compute these values 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.


OpenAddresses data tends to contain lots of duplicate records. In order to avoid inserting this duplicate data into Pelias, the importer can optionally run all records through the openvenues address deduplicator.

Note: The address deduper is a Python/Flask app and defaults to running on port 5000. It must be running in order for deduplication to take place!

The address deduplicator will filter out records that are both nearby, and have nearly identical values. The deduplicator knows to expand common abbreviations, so 123 Main Street and 123 Main St would be matched as duplicates.

Like admin lookup, this process slows down the importer quite a bit, and requires a large amount of disk space (it uses a LevelDB store to track which addresses it has seen), so it defaults to off.


This importer can be configured in pelias-config, in the imports.openaddresses hash. A sample configuration file might look like:

  "esclient": {
    "hosts": [
        "env": "development",
        "protocol": "http",
        "host": "localhost",
        "port": 9200
  "logger": {
    "level": "debug"
  "imports": {
    "whosonfirst": {
      "datapath": "/mnt/data/whosonfirst/",
      "importPostalcodes": false,
      "importVenues": false
    "openaddresses": {
      "datapath": "/mnt/data/openaddresses/",
      "files": [ "us/ny/city_of_new_york.csv" ]

The following properties are recognized:

This importer is configured using the pelias-config module. The following configuration options are supported by this importer.

key required default description
deduplicate no false Boolean flag to enable deduplication (see above).
datapath yes The absolute path of the directory containing OpenAddresses files. Must be specified if no directory is given as a command-line argument.
files no An array of the names of the files to download/import. If specified, only these files will be downloaded and imported, rather than all .csv files in the given directory. If the array is empty, all files will be downloaded and imported. Refer to the OpenAddresses data listing for file names.
