Siti OSS
Situational Intelligence Open Source Software
↓
Siti OSS (formerly CogniCity) is a free and open source software for community-led information sharing. The system gathers, sorts, and displays real-time data directly from, and back to, people affected by various environmental changes. Designed as an inclusive and accessible tool, it has been continuously refined for nearly a decade by the frontline communities who rely on it.
Initiated in 2017, the software now supports over 350 million users across Asia, providing life-saving information during floods, typhoons, volcanic eruptions, earthquakes, and other extreme weather events. The software powers the award-winning disaster mapping platforms PetaBencana.id in Indonesia and MapaKalamidad.ph in the Philippines,
providing hyperlocal intelligence that enables better decision making for residents, emergency managers and first responders.
