This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (osm-pbf-parser) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

osm-pbf-parser

streaming open street maps protocol buffer parser

example

First grab a pbf torrent from http://osm-torrent.torres.voyager.hr/files/rss.xml or from http://download.geofabrik.de/

var fs = require('fs');
var through = require('through2');
var parseOSM = require('osm-pbf-parser');

var osm = parseOSM();
fs.createReadStream(process.argv[2])
    .pipe(osm)
    .pipe(through.obj(function (items, enc, next) {
        items.forEach(function (item) {
            console.log('item=', item);
        });
        next();
    }))
;

Then you can parse the results:

$ node parser osm.pbf | head -n15
item= {
  type: 'node',

}

methods

var parseOSM = require('osm-pbf-parser')

var stream = parseOSM()

Return a transform parser stream that takes a binary OSM protocol buffer stream as input and produces parsed objectMode rows as output.

rows

Each row from the output stream has a row.type.

parallel processing

The module exposes BlobParser and BlobEncoder so that you distribute binary work units for parsing. See the pstats example.

install

With npm do:

npm install osm-pbf-parser
