### This library has been deprecated for [somehow-maps](https://github.com/spencermountain/somehow-maps)
thanks

OpenStreetMaps is the coolest project on the web, with the most tangled, but well-meaning apis ever.
So, doing data-queries on a dump is the lonesome place you've found yourself.
this library helps you pluck data from a openstreetmaps dump, and get it into a wicked-small, web format.
It lets you grab all the restaurants, or whatever, and do dirty things with them.
The best strategy to do this, as of 2014, is this.
### download a region data file in ***.pbf*** format here - http://download.geofabrik.de/
```bash
wget http://download.geofabrik.de/north-america/canada/ontario-latest.osm.pbf
```
pbf is completely opaque, but wicked-fast.
### pluck out your data by a particular tag, or amenity, using [osmosis](http://wiki.openstreetmap.org/wiki/Osmosis) like this:
```bash
./build/fetch_xml.sh amenity.grave_yard
./build/fetch_xml.sh amenity.nightclub
```
### wrangle it into geoJSON with
```bash
node ./build/to_json.js
```
### bring it on' home to mercator SVG with d3
```bash
python -m SimpleHTTPServer 8080
chrome http://localhost:8080/build/front_end
```
# Install
osmosis is a pretty opaque java library, but dammnit is it fast. On a mac, you can just hotlink the binary-
```bash
wget http://bretth.dev.openstreetmap.org/osmosis-build/osmosis-latest.tgz
tar xvfz osmosis-latest.tgz
cd osmosis-*
chmod a+x bin/osmosis
bin/osmosis
...and add it to your $path
```
xml-stream is a pretty sweet streaming xml parser, which lets us wrangle ungodly xml without putting them all in memory at once. It requires lower versions of nodejs though:
```bash
nave use 0.10.33
npm install xml-stream
```
