osm2geojson

Streams OSM data in any format to GeoJSON

Install it globally

npm install -g osm2geojson

Use it from the command line

Usage: osm2geojson [options] <filepath>

Options:
  -w, --warn	On invalid data, log warnings to stderr instead of failing
  -n, --nodes	Create GeoJSON for nodes which are not POIs

Use it in another Node.js module

var filepath = '/path/to/osm/data';
var osm2geojson = require('osm2geojson')(filepath);
osm2geojson.pipe(aWritableStream);

Optional warnings

By default, the stream will fail hard and emit an error event if it encounters bad data in the file which cannot be converted to GeoJSON. If you wish to ignore these failures, you can specify the --warn option at the command-line, or provide the failEvents option in JavaScript. The stream will then emit fail events, and listeners will be handed an error object that you can inspect.

var filepath = '/path/to/osm/data';
var osm2geojson = require('osm2geojson')(filepath, { failEvents: true });

osm2geojson.on('fail', function(failure) {
  console.log(failure.message);
  // way!8914650!3 | location of at least one of the nodes in this way not set
});

osm2geojson.pipe(aWritableStream);

Want every node?

By default, nodes that are not points-of-interest (POIs) will not be included in the output. A POI is defined as a node that has tags other than source and created_by. If you wish to include every node, you can use the --node flag at the command-line, or provide the allNodes option in JavaScript.
