Recent research has focused on enabling the representation of, and selection from among, different opinions, while discussion among people has been ignored. This paper reports on a discussion process aimed at reconciling inconsistent perspectives in distributed workgroups. The Speech Act Theory (SAT) of Austin was extended to define both non-spatial and spatial speech acts in the context of a negotiation. A coordination process was modeled by these speech acts. Then, inconsistent perspectives were reconciled using detection of inconsistency, or initial integration of perspectives, or reconciliation of collaborators. The method we propose makes it possible to effectively describe the speech acts and use them to naturally represent the reconciliation process. A prototype system based on this approach was implemented in experiments. Their results demonstrate that a good abstraction of the negotiation process will facilitate the coordination of discussion among people and provide a criterion for system designers.

Web cellular automata: forest fire modeling approach and prototype tool / S. Yassemi in Cartography and Geographic Information Science, vol 35 n° 2 (April 2008)

The objective of this study is to develop an approach to integrate a cellular automata (CA) forest fire behavior model with the world wide web. The developed CA model extends the capability of the static raster GIS by incorporating spatial dynamics into the forest fire phenomena. The developed CA model comprises topographic, forest fuel and weather variables as the key drivers of forest fires. The web-based modeling environment used ASP.NET as the server-side platform, and client-side programming with JavaScript extended the functionality of the web client. The web-based CA model and its consistent user-friendly interface will provide fire managers with a decision support and rapid disaster management tool with such advantages as access to real-time geospatial and environmental data, computer platform independence, and enhanced accessibility of spatial modeling tools.

Architecture design and prototyping of a Web-based, synchronous collaborative 3D GIS / Z. Chang in Cartography and Geographic Information Science, vol 35 n° 2 (April 2008)  

Public [article]  inCartography and Geographic Information Science > vol 35 n° 2 (April 2008) . - pp 117 - 132 Titre : Architecture design and prototyping of a Web-based, synchronous collaborative 3D GIS Type de document : Article/Communication Auteurs : Z. Chang, Auteur ; S. Li, Auteur Année de publication : 2008 Article en page(s) : pp 117 - 132 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Systèmes d'information géographique [Termes IGN] aide à la décision [Termes IGN] architecture de système [Termes IGN] composant SIG [Termes IGN] SIG 3D [Termes IGN] SIG participatif Résumé : (Auteur) Collaborative GIS has emerged as an efficient, spatial decision-making tool, especially when 3D GIS models are integrated. While centralized architecture is still dominating the design and development of such tools and/or systems, alternative architecture, such as peer-to-peer (P2P), and hybrids have been given increasingly more attention in designing more scalable and efficient systems. This paper presents a conceptual hybrid system architecture for the development of integrated, synchronously collaborative environments with 3D GIS tools for group decision-making and 3D information sharing. In this paper, we discuss the major design issues related to such an architectural design and identify the spatial requirements of synchronous collaborative 3D GIS. A hybrid architectural model integrating centralized and replicated computing architecture is then designed to address the identified requirements. The proposed architecture was tested using data/message flow models developed to facilitate component-based collaborative 3D GIS systems. The results show that collaborative 3D GIS require collaboration computing different from that applied in generic GIS systems, and that a component-based development approach can lead to more light-weight systems.

SIEVE: collaborative decision-making in an immersive online environment / C. Stock in Cartography and Geographic Information Science, vol 35 n° 2 (April 2008)  

Public [article]  inCartography and Geographic Information Science > vol 35 n° 2 (April 2008) . - pp 133 - 144 Titre : SIEVE: collaborative decision-making in an immersive online environment Type de document : Article/Communication Auteurs : C. Stock, Auteur ; I.D. Bishop, Auteur ; et al., Auteur Année de publication : 2008 Article en page(s) : pp 133 - 144 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Systèmes d'information géographique [Termes IGN] géomatique web [Termes IGN] monde virtuel [Termes IGN] outil d'aide à la décision [Termes IGN] réalité virtuelle [Termes IGN] SIG 3D [Termes IGN] SIG participatif [Termes IGN] visualisation dynamique Résumé : (Auteur) Over the recent years, spatial data have become more accessible to members of the public, and there is an increased awareness that spatial data are an essential ingredient in the development of governance policies. In parallel, computing devices that can render real-time 3D environments in nearly photo-realistic quality have become a common household item. Integrating spatial data and virtual environments opens the possibility of presenting spatial data in a highly visual way—the same way we experience our everyday world. We have developed a landscape planning tool called SIEVE (Spatial Information and Visualization Environment), which allows users to explore existing spatial data and hypothetical future scenarios in a real-time 3D environment, links to environmental process models outcomes, and also provides a collaborative decision-making environment. SIEVE has an automatic model-building component that allows users to select a region on a 2D map using a web portal and to download automatically generated 3D landscape environments. SIEVE not only models above-ground features but also incorporates underground features. This allows users to see the connection between below- and above-ground processes. Lastly, SIEVE incorporates a multi-user environment that allows users from different locations to gather in the virtual landscapes for exploring and decision-making purposes.
