Abstract

Geographic phenomena exist within a multi-dimensional space-time continuum, at various levels of detail. Dynamic geographic phenomena can be generally conceptualized and represented as spatiotemporal patterns (e.g., trajectories of people or animals, flows of chemicals, or movements of eyes over maps), space-time processes (climate change, urban growth, human spatial cognition) or spatiotemporal events (e.g., earthquakes, Winter Olympics, or human eyes fixating on a perceptually salient object in a scene). Humans rarely care about spatiotemporal entities in isolation. Visualization and analysis approaches that focus on individual spatiotemporal phenomena in isolation are likely doomed to failure because they miss the relational structure humans use to process and reason about events. This idea may be counter intuitive and thus counter to a scientist’s natural inclination to analyze a phenomenon to its elements. Only a few researchers have looked specifically at modeling and visualizing relationships of spatiotemporally coordinated events (Laube et al. 2005; Andrienko & Andrienko 2007; Stewart Hornsby & Yuan 2008), and even fewer have done so using animated displays to depict spatiotemporal information in a perceptually salient and cognitively inspired manner (Fabrikant & Goldsberry 2005; Griffin et al. 2006; Klippel, 2009). We contend that a static and geometric decompositional approach to spatiotemporal patterns and processes limits the field’s ability to develop tools that can be applied to a broad class of spatiotemporal data, or events, that are important to users. This class represents spatiotemporally coordinated events (a car changing movement direction because of road works, a hurricane not making landfall because of changing wind direction, etc.). In this position paper we argue for the need for perceptually salient and cognitively inspired animated displays that help humans to more effectively and efficiently detect relationships in complex spatiotemporally coordinated events.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
