With thousands expected to fly to Brazil for the 2016 Olympic Games, a new project has mapped out slum areas, known as Favelas, in Rio De Janeiro, aiming to economically capitalize on the city’s influx of sports tourists in the city that has over 1,000 previously-neglected areas.

AfroReggae Cultural Group’s Tá no Mapa digitally maps the informal settlements for the first time, with details on their history, communities and the number of residents.  The initiative seeks to “promote citizenship, growth of local market and access to public services.”

So who collects the data? Favela residents joined the project, becoming mapping agents after receiving adequate training. The agents take pictures and enter details and information on their neighborhoods, the streets and local businesses. The data is then sent to Google who maps it digitally.

Partnering with AfroReggae Cultural Group, international advertising agency J. Walter Thompson (JWT) expresses that Rio’s favelas are filled with stories that are waiting to be told. The project started with Parada de Lucas and, where over 20,000 people live. Other mapped areas included São Carlos, Babilônia, Cantagalo, Santa Marta, Mineira, Vidigal, Rocinha, among others.
