Rio Emergency Management Center
IBM continues to lead the integration of a wide number of city information to help the city of Rio manage the activities in the city. This article from the NY Times goes into some considerable depth to describe the work and analytics that has been accomplished. A large part of the underlying innovation is the 1 km resolution weather prediction which provides parameters such as rainfall and predicts the degree of flooding in the city. It does this for a 48 hour period every 12 hours.
