Constraints serve to improve the usability of geovirtual environments by guarding the navigation and interaction processes of users. In addition, they facilitate the implementation of Digital Rights Management for geovirtual environments. The presented approach distinguishes spatial constraints, structural constraints, and redistribution constraints. Several types of spatial constraints have been identified for navigation in geovirtual environments. To demonstrate their applications, this paper reports on using constraints in virtual 3D city models.

Designing the next generation of distributed geocollaborative tools / W.A. Schafer in Cartography and Geographic Information Science, vol 32 n° 2 (April 2005)  

Public [article]  inCartography and Geographic Information Science > vol 32 n° 2 (April 2005) . - pp 81 - 100 Titre : Designing the next generation of distributed geocollaborative tools Type de document : Article/Communication Auteurs : W.A.

Ganoe, Auteur ; et al., Auteur Année de publication : 2005 Article en page(s) : pp 81 - 100 Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Infrastructure de données [Termes IGN] interactivité [Termes IGN] métadonnées [Termes IGN] métadonnées géographiques [Termes IGN] SIG nomade [Termes IGN] synergiciel [Termes IGN] système d'information géographique [Termes IGN] temps réel [Termes IGN] travail coopératif Résumé : (Auteur) Geocollaboration is a new field of research that investigates how technology can support human-human collaboration with geospatial information. This paper considers the design issues inherent in distributed geospatial software. It looks at providing a non-spatial communication channel, supporting real-time synchronous awareness, designing interaction techiques, establishing common ground, and using floor control and attention techniques. Using examples from existing geocollaboration tools and realistic geocollaboration scenarios, it demonstrates some of the design alternatives for geocollaboration. The paper concludes with a future research agenda describing the complexities in supporting longer-term geocollaboration activities.

Deciding on fitness for use: evaluating the utility of sample maps as an element of geospatial metadata / Paula Ahonen-Rainio in Cartography and Geographic Information Science, vol 32 n° 2 (April 2005)  

Public [article]  inCartography and Geographic Information Science > vol 32 n° 2 (April 2005) . - pp 101 - 112 Titre : Deciding on fitness for use: evaluating the utility of sample maps as an element of geospatial metadata Type de document : Article/Communication Auteurs : Paula Ahonen-Rainio, Auteur ; Menno-Jan Kraak, Auteur Année de publication : 2005 Article en page(s) : pp 101 - 112 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Infrastructure de données [Termes IGN] évaluation des données [Termes IGN] information géographique [Termes IGN] métadonnées [Termes IGN] métadonnées géographiques [Termes IGN] outil d'aide à la décision [Termes IGN] santé [Termes IGN] visualisation Résumé : (Auteur) Metadata that describe characteristics of geographic datasets are used to discover potential datasets and evaluate their suitability for intended purposes. Here sample maps are suggested as tools for evaluating datasets. Their usefulness in this process was studied as part of a wider research on visualization of geospatial metadata. First, design concepts were tested with twelve subjects who commented different static presentations of sample maps and multivariate visualizations. Then a prototype of an interactive metadata environment composed of sample maps, textual metadata documents, and a parallel coordinate plot was tested with eighteen subjects whose task it was to select the most suitable dataset from among six alternatives each of which represented the same theme. The subjects determined suitalbilitv within a use scenario. The prototype proved to be a valuable tool in the evaluation process, especially because multiple maps could be compared.

Multivariate analysis and geovisualization with an integrated geographic knowledge discovery approach / D. Guo in Cartography and Geographic Information Science, vol 32 n° 2 (April 2005)  

Public [article]  inCartography and Geographic Information Science > vol 32 n° 2 (April 2005) . - pp 113 - 132 Titre : Multivariate analysis and geovisualization with an integrated geographic knowledge discovery approach Type de document : Article/Communication Auteurs : D. Guo, Auteur ; M. Gahegan, Auteur ; et al., Auteur Année de publication : 2005 Article en page(s) : pp 113 - 132 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Information géographique [Termes IGN] analyse multivariée [Termes IGN] carte de Kohonen [Termes IGN] découverte de connaissances [Termes IGN] données cartographiques [Termes IGN] échantillon [Termes IGN] interactivité [Termes IGN] visualisation de données Résumé : (Auteur) The discovery, interpretation, and presentation of multivariate spatial patterns are important for scientific understanding of complex geographic problems. This research integrates computational, visual, and cartographic methods together to detect and visualize multivariate spatial patterns. The integrated approach is able to: (1) perform multivariate analysis, dimensional reduction, and data reduction (summarizing a large number of input data items in a moderate number of clusters) with the Self-Organizing Map (SOM); (2) encode the SOM result with a systematically designed color scheme; (3) visualize the multivariate patterns with a modified Parallel Coordinate Plot (PCP) display and a geographic map (GeoMap); and (4) support human interactions to explore and examine patterns. The research shows that such "mixed initiative" methods (computational and visual) can mitigate each other's weakness and collaboratively discover complex patterns in large geographic datasets, in an effective and efficient way.
