Fast and flexible Javascript library for working with OpenStreetMap data.
Provides a bindings to the libosmium C++ library.
- Node.js v0.10.x
By default, binaries are provided and no external depedencies and no compile is needed.
Just do:
npm install osmium
We currently provide binaries for 64 bit OS X and 64 bit Linux. Running npm install on other
platforms will fall back to a source compile (see Developing below for build details).
var osmium = require('osmium');
var file = new osmium.File("test/data/winthrop.osm");
var reader = new osmium.Reader(file);
console.log(reader.header())
{ generator: 'CGImap 0.2.0',
bounds: [ -120.2024, 48.4636, -120.1569, 48.4869 ] }var osmium = require('osmium');
var file = new osmium.File("test/data/winthrop.osm");
var reader = new osmium.Reader(file);
var handler = new osmium.Handler();
var nodes = 0;
handler.on('node',function(node) {
++nodes;
});
reader.apply(handler);
console.log(nodes);

git clone https://github.com/osmcode/node-osmium.git
cd node-osmium
make
make test
- Compiler that supports
-std=c++11(>= clang++ 3.2 || >= g++ 4.8) - Boost >= 1.49 with development headers
- OSM-Binary
- Protocol buffers
- zlib
Set depedencies up on Ubuntu Precise (12.04) like:

sudo apt-add-repository --yes ppa:mapnik/boost
sudo apt-add-repository --yes ppa:ubuntu-toolchain-r/test
sudo apt-get -y update
sudo apt-get -y install git gcc-4.7 g++-4.7 build-essential nodejs libboost-dev zlib1g-dev protobuf-compiler libprotobuf-lite7 libprotobuf-dev libexpat1-dev libsparsehash-dev
export CC=gcc-4.7
export CXX=g++-4.7
git clone https://github.com/scrosby/OSM-binary.git
cd OSM-binary/src
make && sudo make install
Set depedencies up on OS X like:
git clone https://github.com/mapnik/mapnik-packaging.git
cd mapnik-packaging/osx
# open the settings and make `export CXX11=true`
