GeoTemCo: Comparative Visualization of Geospatial-Temporal Data

The amount of online data annotated with geospatial and temporal metadata has grown rapidly in the recent years. Providers like Flickr and Twitter are popular, but hard to browse. Many systems exist that, in multiple linked views, show the data under geospatial, temporal, and topical aspects. GeoTemCo is a web-application which allows the comparative analysis of such data. It consists of several views showing the datas' several dimensions: a map view for the geospatial distribution of items, a time view for the temporal distribution of items and a detail view for the inspection of individual items. A broad range of interaction abilities allow the explorative comparison and analysis of different datasets representing different topics. In this presentation, we want to demonstrate the design of GeoTemCo, take a look at some case studies and introduce several projects which utilize GeoTemCo for various purposes.
