Abstract
Collaboration and decision-making of humans usually entails logical reasoning that is expressed through discussions and individual arguments. Where collaborative work uses geo-spatial information and where decision-making has a spatial connotation, argumentation will include geographical references. Argumentation maps have been developed to support geographically referenced discussions and provide a visual access to debates in domains such as urban planning. The concept of argumentation maps provides for explicit links between arguments and the geographic objects they refer to. These geo-argumentative relations do not only allow for cartographic representation of arguments, but also support the querying of both, space and discussion. Combinations of spatial queries and retrieval of linked arguments provide a powerful way of analyzing and summarizing the current state of a debate. In this chapter, we provide an overview of the original argumentation model and we discuss related research and application development. We also link argumentation mapping to related concepts in geographic visualization, spatial decision support systems, and public participation GIS under the umbrella of collaborative GIS.<div> Geographic Information Systems, Public Participation GIS, Collaborative GIS, Spatial Decision Support Systems, Argumentation Maps, Spatial Planning, User Interface.</div>
Highlights
Collaboration almost imperatively entails argumentation, that is, the exchange of personal views on certain topics, in particular using logical reasoning
Argumentation maps have since been discussed in the context of “place-based group knowledge building” (MacEachren et al 2004) and geo-collaboration (MacEachren & Brewer 2004), and the approach has been summarized in a textbook on “Information Systems for Urban Planning” (Laurini 2001)
A measured temperature can be linked to the location where it occurred by being stored as a numeric value in a grid cell
Summary
Collaboration almost imperatively entails argumentation, that is, the exchange of personal views on certain topics, in particular using logical reasoning. Argumentation maps were developed by Rinner (1999b, 2001) as a concept for computer support of geographically referenced discussion by cartographic visualization and query functionality. In this book chapter we will review the original concept and related research from a collaborative GIS perspective, and comment on existing argumentation map implementations. The time-space taxonomy of groupware tools has been adopted by Armstrong (1993) and Shiffer (1997) in the context of collaborative spatial decisionmaking and by Janelle (1995) from the perspective of time geography In this text, we will focus on asynchronous distributed communication. Conklin & Begeman (1988) propose a hypertext tool that implements the IBIS method Their graphical IBIS (gIBIS) and its successors QuestMap and Compendium (Conklin et al 2003) provide examples for argumentation visualization through graphical representations of argumentation elements and their relations. We deal with argumentation maps in a cartographic sense
