FloodTags monitors floods and wildfire by using public media data. Data sources include social media such as Twitter, online news articles, blogs, forums, YouTube, Facebook public pages, and we connect to messengers such as WhatsApp and Telegram. We analyse the media data by using a mix of artificial intelligence, natural language processing and image processing. Applications include emergency flood response, index-insurance, fact-finding studies, model validation (incl. early warning and impact forecasting), satellite imagery acquisition and satellite tasking. FloodTags believes that citizens and local communities are key resources in any social and water management problem. By listening to and anticipating on local perspectives, decision makers can take supported measures and responders have direct insight in the assistance needed on-the-ground. Our aim: Help 100 million people by enabling engineers and managers to listen, understand and keep in touch with the situation on-the-ground.
