In recent years more and more data about the city is digitally collected. This data from sources such as mobile phones, sensors, and location-based services can be visualized to reflect urban activity. Geovisualization stimulates the visual analysis of spatial patterns, relationships, and trends, as well as enables interactive exploration and understanding of location-based information. Usable and approachable visualizations allow casual users and experts alike to make sense of the massive streams of data, to see the city in different perspectives, and to understand their environment. I will talk about the challenges in urban data visualization in regard to user experience and interaction design, as well as showcase multiple projects that demonstrate current approaches to and new thinkings about urban data.
