Overview
========

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

1. `Retrieving OpenStreetMap data <../../notebooks/L6/retrieve_osm_data.ipynb>`__
2. `Network analysis in Python <../../notebooks/L6/network-analysis.ipynb>`__
3. :doc:`Exercise 6 <exercise-6>`

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
