The second Udacity course for my Data Analyst Nanodegree was Data Wrangling with MongoDB. The project submission instructions were:

Choose any area of the world in https://www.openstreetmap.org and use data munging techniques, such as assessing the quality of the data for validity, accuracy, completeness, consistency and uniformity, to clean the OpenStreetMap data for a part of the world that you care about.

You can find my submission here and all of the source files here.
