UN Global Pulse: combining "big" and "small" data to build resilience in Jakarta
Global Pulse, a UN initiative to foster and understand the use of Big Data to tackle development and relief issues, gives us a concrete example with the case of floods in Jakarta.
In this article, the two directors of the project PetaJakarta explain how they intend to collect and use "small data" (data produced by individuals) and "big data" (data from statistical sources) to built resilience in order to prepare and overcome floodings, which are common in this city.
This project is also interesting because of the possibility of using such a system in other cities and contexts, and for different local issues. As the directors of the project put it:
"To summarize, our GeoSocial Intelligence Framework is one way of integrating a crowdsourcing methodology, social media data, and big data analysis to enable evidence-based, real-time decision making about urban infrastructure. We are now pilot-testing this framework as a means to coordinate the response to extreme weather events, including flooding in Jakarta, but it is transferable to other cities, other languages, and other urban issues, like waste and sewage management, traffic congestion, etc."
