Overview
========

In this week we will see how to easily retrieve OpenStreetMap data and how to do simple
network analysis in Python.

Learning goals
--------------

After this week's lesson you should be able to:

- Retrieve data from OpenStreetMap using Python
- Extract simple street network properties and statistics (centrality measures etc.)
- Do simple route optimization using shortest path algorithm in OSMnx / Networkx

This week's lecture materials are based on documentation of `osmnx <https://github.com/gboeing/osmnx>`__, `networkx <https://networkx.github.io/documentation/stable/>`__
and `OpenStreetMap <https://wiki.openstreetmap.org/wiki/Main_Page>`__.
