Visualizing the city: communicating urban design to planners and decision-makers
There are now a wide array of new digital tools that are able to support the generic activity of planning and design. In urban design, these tools support different stages of the planning process which involve rapid and effective storage and retrieval of information, various kinds of visualization which inform survey and analysis as well as design itself, and different strategies for communicating information and plans to various publics from design professionals to the affected community. In this paper, we begin by noting the activities that such digital tools can support, emphasizing methods of visualization, and specifically focusing on integrated 2d mapping and 3d block modeling. We then review the state-of-the-art, worldwide, suggesting that there are rapid changes taking place in how such visualizations are being developed. We note developments in remotely sensed survey and in the development of 3d models integral to spatial databases as reflected in geographic information systems (GIS) in contrast to computer-aided design (CAD). We illustrate these ideas with respect to developments in world cities, specifically London, where we review initial attempts at the design of virtual cities. We then show two related but different ways of constructing such models: first in ad hoc fashion by linking various proprietary software based on internet GIS, rapid photorealistic CAD, and panoramic imaging; and second through a tighter coupling between 2d and 3d GIS which is highly suited to the new digital data from remote sources such as LIDAR (LIght Detection And Ranging). We conclude with a discussion of different ways in which these visualizations might be automated and delivered to users, in stand-alone manner or over the net.
Virtual cities and landscape models-what has photogrammetry
The demand for geocoded (geographical, spatial) data will considerably grow for the next years. One driving force is the Internet, which allows the user to visit all spots on the Earth if their data is digitally stored and web-accessable. Another request for digital landscapes and city models comes from the communication technology to provide transmitters at the right spots and therefore to overcome 'dead areas' of mobile communication. In near future mobile phones evolve to Personal Digital Assistants (PDAs) offering the power of local information systems to allow for navigation, routing, visualization of 3D location data, queries of shop offers etc. Further examples could easily be cited, but would overload this abstract. Photogrammetry as a science and technology of acquisition and processing of photographically (currently evolving in opto-electronically generated) images for determination of form, shape, position or characteristics of arbitrarily features is the answer to generate virtual cities and landscapes. This paper features photogrammetry according to its products and integrates it in an interactive multimedia environment.

A wide range of visualizations have been developed and implemented as tools for urban simulations and visual impact assessment. These include: plans, diagrams, elevations, perspective sketches, renderings, modified photographs (photo renderings and photomontages), slide projections, scale models, movies, videotapes and computer graphics. In the last decade, graphical computer applications have proven to be an increasingly supportive tool in visualization and manipulation of graphical material. This study presents the state of the art of computer visualization in planning. More specifically, the use of web-based computerized visualizations for landscape visual simulation, with the aim to develop a system of visualization techniques as an aid to communicating planning and design scenarios for historically important landscapes and urban places, with particular attention to the city of Nablus in Palestine. This has led to the evaluation of possibilities and potentials of computer use in this field, and to the definition of the visual problems and challenges of the city of Nablus. This study will argue what extra one can draw from computerized visualizations, what is likely to be its impact on future planning and design research, and what this visualization experience really means for historical important locations as in Nablus. The study demonstrates that computerized visualizations can be a powerful tool in representing a cityscape in three-dimensions from different angels. Visualizations will allow better understanding of the components of the city, its landscapes, city features and the process of change. In this way it may provide new and better platforms for public participation in planning.
Visualizing urban development: improved planning & communication with 3D interactive visualizations
2016
Unfortunately, many landscape architects, urban designers, and city planners currently re-frame from using such gaming technology capable of creating 3D interactive visualizations (Deane, 2015a). Many firms use verbal descriptions with images. This method is insufficient for facilitating feedback (Bratteteig & Wagner, 2010; Gordon, et al, 2010; Stakeholder Engagement, 2009; Zhang, 2004). According to Lange and Bishop (2005) there is no reason why real-time visualizations should not be used in urban design. Design fields will be moving toward procedural modeling software that is code-based to quickly model urban development (Flachbart & Weibel, 2005). However, this type of software, i.e., ESRI CityEngine, is only being used by approximately 10% of firms (Deane, 2015a). This paper is one of the first to analyze how ESRI CityEngine can be used and improved to support the workflow of landscape architects, urban designers, and planners for urban development projects. The project explored ESRI CityEngine's procedural modeling and metric capabilities, and how it could be used to visualize a proposed Urban Core Residential District in Manhattan, Kansas. This process involved Visualizing Urban Development: Improved Planning & Communication with 3D Interactive Visualizations
Coupling 3D visualisation to qualitative assessment of built environment designs
Landscape and Urban Planning, 2001
Geographical information systems (GIS) coupled to 3D visualisation technology is an emerging tool for urban planning and landscape design applications. The utility of 3D GIS for realistically visualising the built environment and proposed development scenarios is much advocated in the literature. Planners assess the merits of proposed changes using visual impact assessment (VIA). We have used Arcview GIS and visualisation software called PolyTRIM from the University of Toronto, Centre for Landscape Research (CLR) to create a 3D scene for the entrance to a University campus. The paper investigates the thesis that to facilitate VIA in planning and design requires not only visualisation, but also a structured evaluation technique (Delphi) to arbitrate the decision-making process. #
Visualization and landscape laboratories in planning, design and management of urban woodlands
Forest Policy and Economics, 2006
Although participatory approaches are increasingly used in planning and management of urban woodlands, efficient tools are also needed to make the processes work. In urban forest planning impacts of proposed management regimes on aesthetic and recreational values are among the factors that interest the local residents the most. This article explores two potential methods for improving collaborative urban forest planning and design in Europe, based primarily on experience gained in the Nordic countries. The methods relate to the use of (i) computer-based visualization methods and (ii) demonstration forests and landscape laboratories. We suggest that use of both methods may lead to a major enhancement in forest planning and design. D

Architectural works are carefully planned before they are erected. They are the result of an elaborated and logical process. The survey of a building is thus a singular problem compared to the contingent constitution of the rural survey. Architectural modeling can therefore be enriched beyond its dimensional knowledge by adding to it the architectural knowledge that permitted its construction. The virtual model of an element of architecture is significant when it becomes displayable. 3D visualization is however a translation of information provided by a model. The result obtained is a communication tool, not a vehicle for knowledge. The data used for its construction is transformed in order to satisfy the illusion. The geometry and textures are adjusted together. The visualization mission of the Promenade du Peyrou is an occasion for us to apply our principles of analysis to the remote acquisition survey.
