## How To Validate
* Download or update a planet file in o5m format (using `osmconvert` and `osmupdate`).
* Use `osmfilter` to extract a portion of data for all subways.
* Choose transport data source:
1. Download or update a planet file in o5m format (using `osmconvert` and `osmupdate`).
Run `osmfilter` to extract a portion of data for all subways. Or
2. If you don't specify `--xml` or `--source` option to the `process_subways.py` script
it tries to fetch data over [Overpass API](https://wiki.openstreetmap.org/wiki/Overpass_API). **Not suitable for whole planet or large countries.**
* Run `process_subways.py` with appropriate set of command line arguments
to build metro structures and receive a validation log.
* Run `validation_to_html.py` on that log to create readable HTML tables.
