Summary
For decades, studies in urban sciences were dominated by authoritative data sources. In recent years, we have seen new players entering the game—citizens themselves started to contribute to mapping, monitoring, analyzing, and evaluating urban environments. This novel way of data collection, powered by regular citizens worldwide, potentially allows the obtainment of data that would not be otherwise available. In this presentation, I want to introduce our team’s efforts in harnessing the potential of crowdsourcing geospatial data to address urban challenges and understand urban environments. I believe the growing popularity of crowdsourcing geospatial data is likely to reshape the conceptual, applicable, and analytical paradigms of urban sciences. This presentation serves as a review of what our team has contributed to this domain and encourages a series of systematic investigations on the potentials crowdsourcing geospatial data.
