Location: Virginia A

In the half century since publication of Bertin’s Sémiologie Graphique, we have witnessed substantial changes in cartography and in related visualization and GISCience research fields. There has been a dramatic evolution (if not revolution) in science and technology related to geographical information, its processing, its accessibility, and its display. Similarly, our understanding of human perception and cognition as they relate to maps and other graphical displays has also progressed fairly rapidly over the past 50 years. Advances in science and technology associated with Big Data generally (not just geographical data), together with advances in understanding of human perception and cognition are central to approaches being taken in (geo)Visual Analytics to develop methods and tools that support reasoning and decision-making in many contexts. Thus, it is worth considering how Bertin’s ideas, that were grounding in his graphic/cartographic expertise and in his intuitions about how humans see and think with static maps of 'small data' (and related graphical displays) apply to current research challenges related to Big Data and Visual Analytics.

This presentation will outline a selection of core ideas articulated by Bertin (emphasizing those from Sémiologie Graphique, but also touching on a few ideas from his later Graphics and Graphic Information Processing). First, a few key impacts of these ideas on subsequent developments in geovisualization and information visualization will be outlined. A core question to be addressed here is “How robust have Bertin’s ideas been to changes in technology for maps and related graphics (e.g., from static print to interactive web and smart phone) and to changes in the roles that these display forms have taken on?”. Next, building on this base, attention will be directed to the current role of Bertin’s ideas in the context of Big Data and Visual Analytics. Key issues that will be considered include the challenges of: data volume, dynamic data, data heterogeneity, and interactivity. Additionally, the role of visual representations in thinking will be addressed in relation to Bertin’s rules for data signification. Questions to be discussed here include: “What is the relevance of Sémiologie Graphique to support of analytical reasoning with interactive visual interfaces?” and “Do we need a second generation Sémiologie Graphique focused on displays making up the interactive visual interfaces of visual analytics applications, and if so what questions should it answer?”
