    and evaluating the use of Web-delivered tools to supplement the community decision-making process. This has involved building and testing a 3D tool for Community Collaborative decisionmaking in the Jewell Station Neighbourhood (JSN). The focus of this decision-making tool provision is placed in an urban planning context. VRML (Virtual Reality Modeling Language) was used to build two tools: a ‘Sandbox ’ and a virtual world. Building the tools was done so that community members, or planning consortia, could use the tools in a group meeting or individually through home Internet computers, or even at Internet cafes. The underlying criterion for design was simplicity and accessibility. The virtual worl

    Online participation: the Woodberry Down experiment

    The internet and world wide web are generating radical changes in the way we are able tocommunicate. Our ability to engage communities and individuals in designing theirenvironment is also beginning to change as new digital media provide ways in whichindividuals and groups can interact with planners and politicians in exploring their future.This paper tells the story of how the residents of one of the most disadvantagedcommunities in Britain ? the Woodberry Down Estate in the London borough ofHackney ? have begun to use an online system which delivers everything from routineservices about their housing to ideas about options for their future. Woodberry Down isone of the biggest regeneration projects in Western Europe. It will take at least 10 years,probably much longer, to complete, at a cost of over £150 million. Online participation isone of the many ways in which this community is being engaged but as we will show, itis beginning to act as a catalyst. The kinds of networks which are evolving aroundsystems like these will change the nature of participation itself, the ways we need to thinkabout it, and the ways we need to respond. Before the experiment is described, we set thecontext by describing the wide range of digital media for communicating plans andplanning which suggests a new typology for web participation consistent with this fastemerging network culture

    Virtual Worlds and Conservational Channel Evolution and Pollutant Transport Systems (Concepts)

    Many models exist that predict channel morphology. Channel morphology is defined as the change in geometric parameters of a river. Channel morphology is affected by many factors. Some of these factors are caused either by man or by nature. To combat the adverse effects that man and nature may cause to a water system, scientists and engineers develop stream rehabilitation plans. Stream rehabilitation as defined by Shields et al., states that restoration is the return from a degraded ecosystem back to a close approximation of its remaining natural potential [Shields et al., 2003]. Engineers construct plans that will restore streams back to their natural state by using techniques such as field investigation, analytical models, or numerical models. Each of these techniques is applied to projects based on specified criteria, objectives, and the expertise of the individuals devising the plan. The utilization of analytical and numerical models can be difficult, for many reasons, one of which is the intuitiveness of the modeling process. Many numerical models exist in the field of hydraulic engineering, fluvial geomorphology, landscape architecture, and stream ecology that evaluate and formulate stream rehabilitation plans. This dissertation will explore, in the field of Hydroscience , the creation of models that are not only accurate but also span the different disciplines. The goal of this dissertation is to transform a discrete numerical model (CONCEPTS) into a realistic 3D environment using open source game engines, while at the same time, conveying at least the equivalent information that was presented in the 1D numerical model

    A multi-modal interface for road planning tasks using vision, haptics and sound

    The planning of transportation infrastructure requires analyzing many different types of geo-spatial information in the form of maps. Displaying too many of these maps at the same time can lead to visual clutter or information overload, which results in sub-optimal effectiveness. Multimodal interfaces (MMIs) try to address this visual overload and improve the user\u27s interaction with large amounts of data by combining several sensory modalities. Previous research into MMIs seems to indicate that using multiple sensory modalities leads to more efficient human-computer interactions when used properly. The motivation from this previous work has lead to the creation of this thesis, which describes a novel GIS system for road planning using vision, haptics and sound. The implementation of this virtual environment is discussed, including some of the design decisions used when trying to ascertain how we map visual data to our other senses. A user study was performed to see how this type of system could be utilized, and the results of the study are presented

    Dissertação apresentada na Faculdade de Ciências e Tecnologia da Universidade Nova de Lisboa para a obtenção do grau de Mestre em Engenharia do Ambiente, perfil Gestão e Sistemas AmbientaisThe present document is a revision of essential references to take into account when developing ubiquitous Geographical Information Systems (GIS) with collaborative visualization purposes. Its chapters focus, respectively, on general principles of GIS, its multimedia components and ubiquitous practices; geo-referenced information visualization and its graphical components of virtual and augmented reality; collaborative environments, its technological requirements, architectural specificities, and models for collective information management; and some final considerations about the future and challenges of collaborative visualization of GIS in ubiquitous environment
