Introduction

Cities are growing globally. While the northern hemisphere experiences a steady but planned development of urban areas, many cities in especially the global south are experiencing urbanization with limited or no development. One of the consequences of this process is slum proliferation.

In this lesson you will learn what remotes sensing techniques can be applied to map and predict slums areas. You will do this using data from the megacity of Lagos in Nigeria.
