In the past few years, citizens have produced a wealth of data using collaborative technologies such as social media and collaborative mapping platforms. Thus, volunteered geographic information (VGI) has emerged as a promising information source for understanding cities and tackling urban challenges. However, acquiring, processing, and identifying high-value content amidst the overwhelming data streams produced by the crowd still poses considerable challenges for research and practice. This talk gives an overview of recent research results and future challenges regarding the different types and usages of VGI in urban contexts, with particular emphasis on the use of VGI for improving urban resilience against natural hazards by managing risks and coping with the consequences of extreme events.
