I explored, cleansed, and analysed OpenStreetMap data for Bogota, Colombia using MongoDB (via Python). I selected the city of Bogotá for a number of reasons. First of all, I know the city fairly well, having lived there for 4 months. I have a specific interest in the developing world, and understanding & building the potentially vast but uncollected data for those parts of the world. Compared to most well-developed countries, which have a high proportion of the population that are connected to the Internet who serve as active users and contributors, cities in developing countries have fewer users to develop and utilize such content.
