About us is supported by a grassroots coalition to harness the power of social media by gathering, sorting, and displaying information about flooding for Jakarta residents in real time.

The platform runs on the open source software known as CogniCity. This GeoSocial Intelligence framework allows data to be collected and disseminated by community members through their location-enabled mobile devices to map information about flooding and water infrastructure in real-time.
