osm2geojson-lite

osm2geojson-lite

A lightweight (not as lightweight as xml2geojson though) yet faster convertor for OSM data whatever in XML or JSON formats to GeoJSON - much faster (the more complex the data source is, the more performance advantages it posesses) than osmtogeojson in most situations - implemented in pure JavaScript without any 3rd party dependency.

History

An internal function inside query-geo-boundary → stripped to handle OSM XML only xml2geojson-lite → this library that supports both OSM XML and JSON

Usage

In Node.JS

Installation:

$ npm install osm2geojson-lite

Usage:

    const osm2geojson = require('osm2geojson-lite');
    let geojson = osm2geojson(osm);

In Browser

    <script src='your/path/to/osm2geojson-lite.js'></script>

    let geojson = osm2geojson(osm);

API

osm2geojson(osm, opts)

Converts OSM data (XML/JSON) to GeoJSON.

• osm: the OSM XML data in String, or OSM/Overpass JSON object
• ?opts: optional, the options object, right now supports below properties/fields:
  • completeFeature/allFeatures: the default value is false. When it's set to true, the returned geojson will include all elements meets the specified conditions in FeatureCollection format; otherwise, only the bare geojson of the first relation element will be returned.
  • renderTagged: the default value is false. When it's set to true, the returned geojson will include all elements with tags (i.e., tagged) until suppressWay changes its behavior a bit; otherwise only the unreferenced ones.
  • suppressWay: by default value os true. When it's set to true, the return value will not include any referenced ways even though they are tagged; otherwise the features of all tagged way will be included, too.

Reminder

Please fasten your seat-belt before run the test script (node test.js)
