# OSM Road Parser

Convert a Open Street Maps `.map` format file into a networkx directional graph.

This parser is based on the osm to networkx tool from aflaxman : https://gist.github.com/aflaxman/287370/

Added :

- python3.6 compatibility

- networkx v2 compatibility

- cache to avoid downloading the same osm tiles again and again

- distance computation to estimate length of each ways (useful to compute the shortest path)

# Installation

```sh

pip install -r requirements.txt

```

# Examples

![OSM exporter](doc/osm_road_exporter.png)

![Networkx graph](doc/osm_networkx_graph.png)

![OSM to SHP](doc/osm_to_shp.png)

- Download osm data and display the networkx graph into matplotlib.

    ```sh

    python examples/display_osm_graph.py

    ```

- Load osm data from a `.map` file and convert the graph to shapefile

    ```sh

    # Requires osgeo python package --> https://pythongisandstuff.wordpress.com/2016/04/13/installing-gdal-ogr-for-python-on-windows/

    python examples/convert_osm_to_shp.py
