## OSM Scripts

Just a collection of scripts that I sometimes use to extract graphs from Open Street Maps.

## Usage

Install npm modules (once):

```

npm install

```

To download JSON file with all roads in the area that matches your search query:

```

node 0.download-city-roads Bellevue > data/bellevue.json

```

To convert it to binary format of a graph:

```

node 1.save-roads-graph.js data/bellevue.json

```

The graph will be saved in a binary format that is described here:
