Abstract
The amount of online data annotated with geospatial and temporal metadata has grown rapidly in the recent years. Social networks like Flickr and Twitter are popular providers of masses of such data, but are hard to browse. Many systems exist that can show the data's geospatial distribution in a map widget and their temporal distribution in a time widget, allowing these widgets to become dynamic-query-like filters for data. We present a web application that combines several existing approaches and supports comparison of multiple, potentially large result sets of textual queries in a geospatial and temporal context with extended interaction capabilities. We validate our approach with several case studies and our tool's learnability in a field experiment.
