There is no suitable social network that would allow: 1) the authorities of a city to contact their citizens of a particular sector/district in real-time to inform them on requested immediate actions needed on their part, and 2) the citizens to be held informed at all times of what is happening in their environment and to communicate efficiently with their immediate neighborhood. In collaboration with Technologies Moments Inc. and the Centre for Research in Geomatics of Laval University, this project aims to design and develop Moments, the first global network of geo-specific communication to meet these two needs.
