osm-node-mongodb

Parse OSM files and insert in MongoDb.It uses sax-js for parsing osm files. The processing is done using sax-stream and node streams and are inserted into mongodb using bulk-insert. Note: A minor change has been done in sax-stream to grep multiple nodes.

Installing

Clone Repository

git clone https://github.com/anand870/osm-node-mongodb.git

Install node modules

npm install

Run

node index.js

How It works

The program currently opens three connections for mongodb at once for node,way and relation collections. It uses bulk insert to insert documents depending on batchSize.

Sample Input

<?xml version="1.0" encoding="UTF-8"?>
<osm>
  <node changeset="10373979" id="25038483" lat="-22.9809491" lon="-43.2068586" timestamp="2012-01-12T21:51:07Z" uid="12293" user="Nighto" version="2">
