This importer uses railway data from OpenStreetMap (visible e.g. on https://openrailwaymap.org) to create a corresponding topology with yaramo objects.

1. Create a virtual environment with python3 -m venv .venv (macOS/Linux) or py -3 -m venv .venv
2. Activate the virtual environment with source .venv/bin/activate (macOS/Linux) or .venv\Scripts\activate.bat
3. Run poetry install

from orm_importer.importer import ORMImporter # any number of points (each being a pair of coordinates separated by a space) representing a polygon polygon = "" topology = ORMImporter().run(polygon)

Examples for how to use the orm-importer can be found in the demo repository.
