## Alternative, using OpenStreetMap
This uses the [osmnx](https://github.com/gboeing/osmnx) python package to get OpenStreetMap data. You will need python and osmnx to run `get_test_polygons.py`.
To help test the Colouring London application, `get_test_polygons.py` will attempt to save a
small (1.5km²) extract from OpenStreetMap to a format suitable for loading to the database.
In this case, run:
```bash
# download test data
python get_test_polygons.py
# load all building outlines
./load_geometries.sh ./
# index geometries (should be faster after loading)
psql < ../migrations/002.index-geometries.up.sql
# create a building record per outline
./create_building_records.sh
# index building records
psql < ../migrations/003.index-buildings.up.sql
```
## Finally
Run the remaining migrations in `../migrations` to create the rest of the database structure.
