Abstract. Spatiotemporal reasoning is the most basic form of human cognition for problem solving. To utilize this potential in the steadily increasing number of mobile and Web applications, significant amounts of spatiotemporal data need to be available. This paper advocates user- generated content and crowdsourcing techniques as a means to create rich, both, in terms of quantity and quality, spatiotemporal datasets.
