Book excerpt: Sophisticated interactive maps are increasingly used to explore information - guiding us through data landscapes to provide information and prompt insight and understanding. Geovisualization is an emerging domain that draws upon disciplines such as computer science, human-computer interactiondesign, cognitive sciences, graphical statistics, data visualization, information visualization, geographic information science and cartography to discuss, develop and evaluate interactive cartography.This review and exploration of the current and future status of geovisualization has been produced by key researchers and practitioners from around the world in various cognate fields ofstudy. The thirty-six chapters present summaries of work undertaken, case studies focused on new methods and their application, system descriptions, tests of their implementation, plans for collaboration and reflections on experiences of using and developing geovisualization techniques.In total, over 50 pages of color are provided in the book along with more than 250 color images on an enclosed CD-ROM.

Download or read book Exploring the Role of Visualization in Climate Change Communication – an Audience Perspective written by Anne Gammelgaard Ballantyne and published by Linköping University Electronic Press. This book was released on 2018-05-08 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change communication is a topical and relevant issue, and it is widely acknowledged that public communication about causes, impacts and action alternatives is integral to addressing the challenges of the changing climate. Climate visualization concerns the communication of climate information and data through the use of different information technologies and different modes of visual representation. In the context of climate change communication, climate visualization is highlighted as a potential way of increasing public engagement with climate change. In particular, developments within information technology have provided significant advancements that are claimed to be transformative in engaging lay audiences with issues relating to the mitigation of and adaptation to climate change. Nevertheless, there is a lack of research exploring climate visualization from an audience perspective. This thesis addresses this gap. The overarching aim is thus to explore the role of climate visualization in climate change communication from an audience perspective, focusing specifically on how lay audiences make meaning of climate change as represented in two examples of climate visualization. In addition, the thesis discusses the potential contributions and/or limitations of climate visualization from a communication perspective. Based on a social semiotic theoretical framework, this thesis employs focus group interviews to study participants’ meaning-making related to two cases of climate visualization: a dome theatre movie developed for Swedish high school students with the aim of encouraging reflection on climate change causes, impacts and mitigation alternatives, and a web-based tool for climate change adaptation developed to assist Nordic homeowners in adapting to the local impacts of climate change. The results of this thesis show that climate visualization can help audiences concretize otherwise abstract aspects of climate change, and that the localized focus can make climate change appear more personally relevant and interesting for targeted audiences. Nevertheless, despite these communicative qualities, the analyses also show that participants’ interpretations are shaped by their preconceptions of climate change as a global and distant issue to be solved by other actors, such as national governments, or through international policy negotiations. Although climate visualization can enhance a sense of proximity with climate change, the localization of climate risk can also lead to participants downplaying the significance of climate impacts. In addition, despite the intentions of inducing a sense of agency in both cases of climate visualization, participants critically negotiated messages concerning their roles as individuals in mitigating or adapting to climate change, and assigned this responsibility onto other actors. These findings show that although climate visualization presents certain communicative qualities, it is not a panacea for engaging lay audiences with climate change. This also underlines the importance of considering cultural and social aspects of the communicative event when studying and developing climate visualization tools as a means of communication. Kommunikation kring klimatförändringar är ett aktuellt och relevant ämne, och många bedömare anser att kommunikation kring orsaker, effekter och åtgärdsalternativ är en viktig del i arbetet med att möta klimatutmaningarna. Klimatvisualisering är en process för att åskådliggöra klimatinformation och klimatdata med hjälp av olika tekniker och metoder för visuell framställning. I forskningslitteraturen om klimatkommunikation lyfts visualisering fram som ett möjligt sätt att öka allmänhetens engagemang i klimatfrågan. I synnerhet har utvecklingen inom informationsteknik lett till betydande framsteg som kan ses som omvälvande när det gäller att engagera lekmän i frågor som rör utsläppsminskningar och klimatanpassning. Det råder dock brist på forskning om klimatvisualisering ur ett mottagarperspektiv. Denna avhandling adresserar denna kunskapslucka. Det övergripande syftet är således att utforska visualiseringens roller i klimatkommunikation ur ett mottagarperspektiv, med särskilt fokus på hur lekmän tolkar innebörden av klimatförändringar så som de representeras i två exempel på klimatvisualisering. Avhandlingen behandlar även klimatvisualiseringens möjliga bidrag och/eller begränsningar ur ett kommunikationsperspektiv. Med utgångspunkt i ett teoretiskt ramverk som inspirerats av socialsemiotiska teorier genomfördes fokusgruppsstudier för att studera deltagarnas meningsskapande i relation till två exempel på klimatvisualisering: en film som visas i en domteater, framtagen för svenska gymnasieelever med målsättningen att uppmuntra till reflektion kring klimatförändringarnas orsaker, effekter och alternativ för utsläppsminskning, samt ett webbaserat verktyg för klimatanpassning, som utvecklats för att stödja husägare i Norden att anpassa sig till klimatförändringarnas lokala effekter. Resultaten av denna avhandling visar att klimatvisualisering kan stödja mottagarna att konkretisera annars abstrakta aspekter av klimatförändringar och att ett lokalt fokus kan få klimatförändringarna att framstå som mer personligt relevanta och intressanta för målgruppen. Dock visar analyserna även, trots dessa kommunikativa kvaliteter, att deltagarnas tolkningar formas av deras förförståelse om klimatförändringar som ett globalt och avlägset problem som ska lösas av andra aktörer, såsom nationella regeringar, eller genom internationella politiska förhandlingar. Även om klimatvisualisering kan förstärka känslan av närhet till klimatförändringar, kan lokaliseringen av klimatriskerna även leda till att deltagare tonar ned de lokala klimatriskernas betydelse. Dessutom, trots att båda fallen av klimatvisualisering avsåg att skapa en känsla av att kunna påverka, blev ansvaret för klimatåtgärder föremål för kritisk förhandling från deltagarnas sida – de förlade ansvaret för att hantera klimatutmaningarna till andra aktörer. Dessa resultat visar att klimatvisualisering visserligen har vissa kommunikativa kvaliteter, men inte är någon patentlösning för klimatkommunikation. Detta understryker även vikten av att ta hänsyn till kulturella och sociala aspekter av den kommunikativa händelsen när man studerar och utvecklar verktyg för klimatvisualisering.
