Situational Intelligence Open Source Software (Siti OSS) (formerly known as CogniCity OSS) is an open source software for real-time disaster mapping and community-powered climate adaptation. Since 2017, Yayasan Peta Bencana has stewarded the development of SITI OSS, in collaboration with CivicDataLab and a growing network of contributors. Today, the software powers disaster information platforms serving 350M+ people across Asia, trusted by over 900 organizations and integrated into official government response systems.

• Transforms high-volume, unstructured data (e.g. social media, chat apps) into verified, real-time, actionable maps
• Enables community participation and coordination in disaster response and risk reduction
• Powers peer-to-peer resource sharing for mutual aid during emergencies
• Delivers automated disaster notifications to keep communities informed
• Builds trust and transparency with two-way information sharing between citizens and government agencies
• Supports open collaboration through APIs and integration with official systems

• Multi-hazard disaster reporting (floods, fires, haze, typhoons, earthquakes, volcanoes, etc.) with customizable templates for localized hazards and adaptive scaling across countries
• Multi-channel input (Telegram, WhatsApp, Messenger, Viber, Twitter/X, web apps)
• Real-time geospatial mapping: high-volume data transformed into clear, actionable, interactive maps
• Multi-language support for diverse communities
• Peer-to-peer resource sharing for mutual aid: request and offer help directly during emergencies
• Automated alerts & notifications
• Government integration into disaster management workflows
• API integration: ingest official data streams
• Dedicated reporting streams for official information to enable two-way transparent information sharing
• Output APIs: interoperable endpoints for NGOs, researchers, developers
• Localization strategy: adaptable across different cultural and governance contexts
• Shared learning infrastructure with communities, universities, and practitioners
• Modular architecture: flexible components for deployment at city, regional, or national scales
