GHC allows for situations to be understood and reasoned with, often with aid of visual representations such as maps. This paper introduces a conceptual model of GHC that theoretically motivates a Geovisual Analytics application called the Context Discovery Application (CDA), which is also presented. The CDA is designed to aid in the production of geo-historical context by using computational processes to identify and extract potentially relevant context information from heterogeneous, implicit situation information. This information can then be explored through visual interfaces to help users explain and understand the information. A hypothetical humanitarian context analysis case study is used to show how the CDA can be applied to real world problems.

The GWR parameter space is treated as a multivariate dataset and explored in a geovisual exploratory environment with the goal to identify spatial and multivariate patterns that describe the spatial variability of the parameters and underlying spatial processes.

The time wave: a new method of visual exploration of geo-data in timespace / X. Li in Cartographic journal (the), vol 45 n° 3 (August 2008)  

Public [article]  inCartographic journal (the) > vol 45 n° 3 (August 2008) . - pp 193 - 200 Titre : The time wave: a new method of visual exploration of geo-data in timespace Type de document : Article/Communication Auteurs : X. Li, Auteur ; Menno-Jan Kraak, Auteur Année de publication : 2008 Article en page(s) : pp 193 - 200 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique [Termes IGN] espace-temps [Termes IGN] exploration de données géographiques [Termes IGN] onde [Termes IGN] représentation graphique Résumé : (Auteur) Today's data-rich environment creates its own problems since exploring and analysing vast volumes of spatio-temporal data have become increasingly difficult. It is suggested to approach this problem not only via location-space or attribute-space as is traditionally done in GIScience, but also via time-space. This time-visualisation approach considers the data, the user tasks and the visualisation representations, and aims to improve accessibility, exploration and analysis of huge amounts of geo-data to support geovisual analytics. To reach this objective, the time wave as the temporal visual representation is introduced. The time wave combines the strengths of both the timeline and the time wheel and as such is able to represent linear and cyclic time simultaneously, even at different levels of granularity. The time wave can be used in its role as temporal reference system, as temporal data representation tool, and as temporal interaction tool. It functions in combination with other graphic representations that are typical for location-space and attribute-space.

Novel method to measure inference affordance in static small-multiple map displays representing dynamic processes / Sara Irina Fabrikant in Cartographic journal (the), vol 45 n° 3 (August 2008)  

Public [article]  inCartographic journal (the) > vol 45 n° 3 (August 2008) . - pp 201 - 215 Titre : Novel method to measure inference affordance in static small-multiple map displays representing dynamic processes Type de document : Article/Communication Auteurs : Sara Irina Fabrikant, Auteur ; S. Rebich-Hespanha, Auteur ; Natalia Andrienko, Auteur ; et al., Auteur Année de publication : 2008 Article en page(s) : pp 201 - 215 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique [Termes IGN] cognition [Termes IGN] inférence [Termes IGN] visualisation cartographique Résumé : (Auteur) Supported by eye-movement data collected during a controlled experiment on small-multiple map displays, a new concept coined inference affordance aimed at overcoming drawbacks of traditional empirical 'success' measures when evaluating static visual analytics displays and interactive visual analytics tools is proposed. Then, a novel visual analytics research methodology is outlined to quantify inference affordance, taking advantage of the well-known sequence alignment analyses techniques borrowed from bioinformatics. The presented visual analytics approach focuses on information reduction of large amounts of fine-grained eye-movement sequence data, including sequence categorisation and summarisation.

Evaluating the effectiveness of representing numeric information through abstract graphics in 3D desktop virtual environments / S. Bleisch in Cartographic journal (the), vol 45 n° 3 (August 2008)  

Public [article]  inCartographic journal (the) > vol 45 n° 3 (August 2008) . - pp 216 - 226 Titre : Evaluating the effectiveness of representing numeric information through abstract graphics in 3D desktop virtual environments Type de document : Article/Communication Auteurs : S. Bleisch, Auteur ; Stephan Nebiker, Auteur ; Jason Dykes, Auteur Année de publication : 2008 Article en page(s) : pp 216 - 226 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique [Termes IGN] efficacité [Termes IGN] monde virtuel [Termes IGN] représentation graphique [Termes IGN] visualisation de données Résumé : (Auteur) The use of bars to represent numeric values in desktop virtual environments that provide information in 3D through monocular depth cues is evaluated. Using empirical experiments we test hypotheses regarding the effectiveness of participants in judging the heights of different bar combinations in four different settings (static 2D and 3D desktop virtual environment with and without frames). The results show that the participants are highly successful in identifying the taller of two bars. However, there are significant differences between the static 2D and 3D desktop virtual environment settings in terms of accuracy and task completion times when comparing bars. Characteristics such as the participant's spatial abilities or the position of the bars in the landscape do not influence the effectiveness of the judgements in our study.

The role of relevance and cognition in attention-guiding geovisualisation / O. Swienty in Cartographic journal (the), vol 45 n° 3 (August 2008)  

Public [article]  inCartographic journal (the) > vol 45 n° 3 (August 2008) . - pp 227 - 238 Titre : The role of relevance and cognition in attention-guiding geovisualisation Type de document : Article/Communication Auteurs : O. Swienty, Auteur ; Tumasch Reichenbacher, Auteur ; S. Reppermund, Auteur ; et al., Auteur Année de publication : 2008 Article en page(s) : pp 227 - 238 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique [Termes IGN] cognition [Termes IGN] convivialité [Termes IGN] pertinence [Termes IGN] prise en compte du contexte [Termes IGN] visualisation cartographique Résumé : (Auteur) It is a delicate task to design suitable geovisualisations that allow users an efficient visual processing of the depicted geographic information. Today, such a design task is subject to three major challenges: the ever growing amount of geospatial data at various levels of detail, the diversified applications of that data, and the continuously expanding range of display sizes. In this work, the aim was to enhance the visualisation of relevant geographic information by focusing on utility and usability issues of designing geographic information representations. The relevance of information as an element of utility and its cognitively adequate visualisation as an element of usability was considered. To enhance utility, irrelevant data was separated from relevant data by implementing relevance as a filter and embodying relevance values as attributes of the selected objects. To represent these relevant objects and the context information design principles were formulated and a design methodology proposed that tends to facilitate a user's attentional capacities when processing geovisualisations. In order to design this attention-guiding geovisualisation, use was made of approaches and findings from relevance theory and cognitive psychology with emphasis on neuroscientific principles. A combination of relevance filtering and a cognitively adequate visualisation improved the overall usefulness of geovisualisations and made a substantial contribution to their practical acceptability. This interdisciplinary approach allowed a more precise and valid evaluation of geovisualisation designs.
