title Artificial Design and Planning Support: Interactive Plan Generation andCoordination in Distributed Decision-Making
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings Avegoor, the Netherlands), 2002
summary In this paper we discuss some basic issues pertaining to artificial plan design as a paradigm for architectural design and urban planning support. We present a model for artificial design generation based on learning control methodologies. Plan design is seen as a search for "coordinated" solutions (changes) that satisfy distributed domain requirements and views expressed by human or artificial agents. Learning control is used as a method to search for solutions that direct partial descriptionsproduced by agents, to follow their dynamically defined targets -despite conflicting requirements. The model is simulated for land use and layout plan design, involving decisions for the location and physical configuration of a hypothetical housing and retail development.

title Formulation of an Urban and Regional Planning System Basedon a Geographical Information System and its Application- A Case Study of the Ishikawa Prefecture Area of Japan -
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings Avegoor, the Netherlands), 2002
summary An Urban and Regional Planning System based on a geographical information system was developed using four sub-systems consisting of a digital map system, a database system, an analysis and forecast system and a planning system. In this case ARCVIEW GIS software was used as a development tool. The digital map system is formulated by the planar orthogonal coordinate system. The data is converted from digital maps issued by the Geographical Survey Institute of Japan (GSI). The database system has layers of data sets, which consist of statistical data, attribute data of geographical points and characteristics of natural features and the built environment. Several sets of principal census data havebeen converted to mesh data. These kinds of data sets are also utilized to this system. LANDSAT TM data is converted into vector data and linked to the same coordinate system. The analysis and forecast system consists of statistical or mathematical analysis, forecasts and visual presentations of the results. The planning system consists of some planning models and reviewing techniques to evaluate alternatives. As an example, this paper examines the relationship between land use and the temperatureon the ground level in built-up areas.

title The Influence of Information and Communication Technology on Spatial Development and Planning
source CORP 2002, Vienna, pp. 453-456
summary We live in an era of rapid change moving towards the information/knowledge/network society. eCity, eRegion, eCountry, eEuropeand the like are targets of many authorities round the world. One of the driving forces of this development is the new information andcommunication technology, ICT. This technology has developed rapidly during the last 20 years and the pace of development of newtools and applications is intense.The microprocessor, personal computer, mobile phone, e-mail, Internet, WWW and a number of software are good examples of ICT.The use of these tools is growing continuously and rapidly. The productivity of industries and effectiveness of services haveincreased. Civil society has found new ways of networking. Individuals have easy access to information around the world. Mobileand wireless communication is becoming commonplace.One aspect of ICT has been rarely discussed and that is: will ICT affect spatial development. During the agrarian era rural areas werethe focus of life, during the industrial era urbanisation took place. Railways and roads shaped spatial structures. Moderntelecommunications can be seen not only as a new way to behave but also as new kind of traffic. New ICT is not limited by location;it affects place and distance as the determinants of location. Thus it can be predicted that ICT as an essential element of informationsociety will reshape in the long run current regional, urban and rural structures and create new spatial forms for urban and rural life.Although there is still only little empirical evidence about n_w spatial development tendencies, a number of scientists have describedthese changes and illustrated what could happen. Land use planners should be aware of these development tendencies and beprepared for the new challenges they are facing.

title Pursuing New Urban Living Environment In The New Millennium: Projecting The Future Of High-Rise And High Density Living In Hong Kong
source International Conference on Generative Art
summary High-rise and high density living is a way of life for most of the 6.7 Million population of Hong Kong. The merits and demerits affiliated with Hong Kong’s compact urban form continues to attract academic deliberations and debates over the acceptability of such urban form as an alternative to urban sprawl for future city and urban life-style. This paper traces the development and causes for Hong Kong’s high-rise and high-density urban form over the past fifty years or so, and focuses its discussions on the pros and cons of high-rise living based on subjective user survey in late 2001 and early 2002. Because of an articulated land shortage, acute topography, escalating population growth, and shortage of time, Hong Kong government and planners have little options left but to adopt vertical development, resulted in a densely and mixed use urban habitat packed with closely built high-rise residences and commercial buildings. From the survey, it is clear that mixed and intensive land use, high quality of living and recreation infrastructure, efficient public transportation network, and segregation of pedestrian and traffic can facilitate the performance of compact urban form. In addition, most of Hong Kong families have been accustomed to high-rise living pattern and the disadvantages such living pattern might cause on its resident’s social communication and children education are readily ignored by most of the people. Based on the analysis of current living situation and development trends in Hong Kong, new pattern of future city form is conceived to be a likely applicable development way in a coastal city with such high density as Hong Kong in the next 50 years. Design countermeasures are presented in this paper to suggest ways of alleviating the pressure of the forever-increasing house requirements in Hong Kong. high-density, high-rise, compact city, social acceptance, life-style.

title Urban Sprawl Modelling: Combining Models to Make Decision
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings Avegoor, the Netherlands), 2002
summary Urban sprawl is frequently associated with the idea of an unsuitable development, leading to increasing economic, social and environmental problems. Moreover, its control is difficult because multiple patterns (concerning numerous traditional urban planning fields) overlap. In order to understand the sprawl process and to manage its consequences, it must be simplified. The construction of a decision making tool appears then interesting. The GIS-based tool presented here is being developed incollaboration between the urban planning agency of Belfort and the laboratory of geography of Strasbourg. It requires three steps: 1. quantification of the sprawl (how much areas are involved in theurban sprawl process?); 2. location of the sprawl (where are the areas defined in the first step?); 3. differentiation of the sprawl (what are the areas located in the second step?). Of course, the successionof the three stages makes the use of the complete model more complex. So, a global ergonomic user interface is being developed within the GIS, allowing to modify each parameter and to play easily numerous simulations.

title Evolution of Media for Early Design Stages
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary In this paper the evolution of media used at early design stages will be considered. In traditional methods of searching and presenting the design idea, the basic tool used was the graphic representation. Implementation of new digital techniques in 60s - 70s focused on the mathematical way ofrepresentation. These methods were “not architect friendly” (lack of graphic representation traditionally used by architects). As a result, the development of methods for digital support of form searching was terminated. The computer was used as a tool for drafting. Creative usage of computers for form searching through sketching on the display was extremely difficult. The computer could be described as an “incompatible pencil”. Only in recent years can we see new efforts in this area ofdesign methodology. Thanks to new technical possibilities we have a new chance for changing the process of designing. New kinds of software and hardware let us use the computer not as a pen, but as a medium. In this paper different new ways of form searching will be considered (from very simple method as the scansketches to very complicated ones, such as the generic algorithms). At the end, the influence of new media on the process of design will be presented.

title Evaluating the Use of a Web-Based Collaborative Interactive Digital Model (CollABITA) in Supporting the Urban Design Approval Process1
source UMDS '02 Proceedings, Prague (Czech Republic) 2-4 October 2002, III.1-III.15
summary This research, after analyzing the Urban Development Approval Process in its functionalities and methodologies, is showing the key points at which the process might be supported by new computer technologies, and it establishes a web-based Collaborative Interactive Digital Model (CollABITA Model) that relates and facilitates the graphical representation of the urban design process with some elements of the methodological approach. The CollABITA Model will dramatically facilitate the idea of broadening public participation, and indirectly by this, also collaboration. This new web-based support tool, is focusing on how new Informative Computer Technologies can be used in order to have a more co-operative design process. By utilizing the enormous potential of Internet for informing the process, and software for visualizing its products, the Model will provide an effective support, which will be able to deliver information in various forms to the Designers, Developers, Decision Makers, Agencies and the final user (the Citizens). The Model is concerned with the big challenge of supporting the urban design approval process itself, by exploring different kind of visualizations and communication tools, rather than producing a guide for carrying out the design. CollABITA Model is based on the existent framework structure of the extranet tool already available. Then, more then those, CollABITA Model will try to solve, by adding technical and collaborative functionalities, those issues that are characteristics in the urban design process and that are not jet solved by using one of the software .

title Site pre-cast yard layout arrangement through genetic algorithms
source Automation in Construction 11 (1) (2002) pp. 35-46
summary The use of modular construction has gained wide acceptance in the housing sector. Standardized modular units are often pre-cast on site. The establishment of site pre-cast yard, in particular arranging the pre-cast facilities within the compound, presents real challenge to site management. This complex task is further aggregated with the involvement of several resources with different transport cost. A GA-model is developed for the search for a near optimal layout solution. The fitness function is to minimize the total transport cost for a pre-determined daily output. The use of the model is illustrated by an example. When compared with the best solution within the initial population, 18.45% reduction in cost for resources flow was achieved by the near optimal layout arrangement arrived at the 673rd trial. It is also suggested that the model can be extended to other layout problems such as warehouse and production line.

title A Java3D Tool for Real-Time Collaboration in a Virtual Reality CAADEnvironment
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary Today the development of network-based virtual communities and the use of avatars have brought a new level of complexity to the meaning of virtuality, providing the technology for remote presence and collaborative experiences. In this project the intention was to pursue this articulated vision of VR in order to assist the design profession during the early stages of the design process. The objective was to provide a tool that is capable of creating 3D shapes in a shared VR environment, thus allowing thedesign and its evolution to be shared. The use of the Java programming language was a natural choice for this project. Because of Java’s performance scalability and hardware independence the concept ofCAAD has been extended, making it possible to create a VR environment that can co-exist between high-end supercomputers and standard PCs. The project is currently being tested using PCs and an SGI system running a Reality Centre. The research reported in this paper describes the architecture and application of software that aims to increase the opportunity for collaboration within virtual worlds and enable effective and transparent information exchange.

title Resource-Adaptive 3D Maps for Location Based Services
source UMDS '02 Proceedings, Prague (Czech Republic) 2-4 October 2002, I.29-I.38
summary In this paper, we present a database driven approach for managing and visualizing 3D urban city models and related multimedia content. Such a 3D database is a core component of a 3D Cadastre system (Coors 2002a). In the TellMaris project (IST 2000- 28249, www.tellmaris.com), we will make use of the 3D database to generate 3D maps. The objective of TellMaris is the development of a generic 3D-map interface to tourist information on mobile computers. The interface provides a new concept for creating value added information services on mobile computers for the European citizens related to geographical information. The interface is in the project used for accessing tourist information relevant for boat tourism in the Baltic Sea and Aegean Sea area in the Mediterranean. In this paper we focus on the online generation and compression of 3D-maps in order to make use of these maps in a mobile enviroment.

title Managing Design Knowledge with Mixed-Initiative Dialogue
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary This paper is based on ongoing work in developing interactive interfaces to formal methods for encoding design knowledge. It reports on the development of a shared graphical notation to support user interaction with design knowledge based on mixed-initiative. Mixed-initiativeprovides a model of interaction where both the designer and the knowledge formalism may share responsibility over decisions. The paper discusses how a formal visual notation can support the mixed-initiative mode for developing and managing formal design knowledge. The notation addresses on the dialogue problem between the user and a knowledge basedformalism and illustrates a model of interaction in which the user and the formalism can share and input data through a common shared resource, on a common shared task. The paper demonstrates the use of this notation in common decision tasks and the implications for seamless interaction with design support systems.

title Perception Aspects in Underground Spaces using Intelligent Knowledge Modeling
source Delft University of Technology
summary The intensification, combination and transformation are main strategies for future spatial development of the Netherlands, which are stated in the Fifth Bill regarding Spatial Planning. These strategies indicate that in the future, space should be utilized in a more compact and more efficient way requiring, at the same time, re-evaluation of the existing built environment and finding ways to improve it. In this context, the concept of multiple space usage is accentuated, which would focus on intensive 4-dimensional spatial exploration. The underground space is acknowledged as an important part of multiple space usage. In the document 'Spatial Exploration 2000', the underground space is recognized by policy makers as an important new 'frontier' that could provide significant contribution to future spatial requirements.In a relatively short period, the underground space became an important research area. Although among specialists there is appreciation of what underground space could provide for densely populated urban areas, there are still reserved feelings by the public, which mostly relate to the poor quality of these spaces. Many realized underground projects, namely subways, resulted in poor user satisfaction. Today, there is still a significant knowledge gap related to perception of underground space. There is also a lack of detailed documentation on actual applications of the theories, followed by research results and applied techniques. This is the case in different areas of architectural design, but for underground spaces perhaps most evident due to their infancv role in general architectural practice. In order to create better designs, diverse aspects, which are very often of qualitative nature, should be considered in perspective with the final goal to improve quality and image of underground space. In the architectural design process, one has to establish certain relations among design information in advance, to make design backed by sound rationale. The main difficulty at this point is that such relationships may not be determined due to various reasons. One example may be the vagueness of the architectural design data due to linguistic qualities in them. Another, may be vaguely defined design qualities. In this work, the problem was not only the initial fuzziness of the information but also the desired relevancy determination among all pieces of information given. Presently, to determine the existence of such relevancy is more or less a matter of architectural subjective judgement rather than systematic, non-subjective decision-making based on an existing design. This implies that the invocation of certain tools dealing with fuzzy information is essential for enhanced design decisions. Efficient methods and tools to deal with qualitative, soft data are scarce, especially in the architectural domain. Traditionally well established methods, such as statistical analysis, have been used mainly for data analysis focused on similar types to the present research. These methods mainly fall into a category of pattern recognition. Statistical regression methods are the most common approaches towards this goal. One essential drawback of this method is the inability of dealing efficiently with non-linear data. With statistical analysis, the linear relationships are established by regression analysis where dealing with non-linearity is mostly evaded. Concerning the presence of multi-dimensional data sets, it is evident that the assumption of linear relationships among all pieces of information would be a gross approximation, which one has no basis to assume. A starting point in this research was that there maybe both linearity and non-linearity present in the data and therefore the appropriate methods should be used in order to deal with that non-linearity. Therefore, some other commensurate methods were adopted for knowledge modeling. In that respect, soft computing techniques proved to match the quality of the multi-dimensional data-set subject to analysis, which is deemed to be 'soft'. There is yet another reason why soft-computing techniques were applied, which is related to the automation of knowledge modeling. In this respect, traditional models such as Decision Support Systems and Expert Systems have drawbacks. One important drawback is that the development of these systems is a time-consuming process. The programming part, in which various deliberations are required to form a consistent if-then rule knowledge based system, is also a time-consuming activity. For these reasons, the methods and tools from other disciplines, which also deal with soft data, should be integrated into architectural design. With fuzzy logic, the imprecision of data can be dealt with in a similar way to how humans do it. Artificial neural networks are deemed to some extent to model the human brain, and simulate its functions in the form of parallel information processing. They are considered important components of Artificial Intelligence (Al). With neural networks, it is possible to learn from examples, or more precisely to learn from input-output data samples. The combination of the neural and fuzzy approach proved to be a powerful combination for dealing with qualitative data. The problem of automated knowledge modeling is efficiently solved by employment of machine learning techniques. Here, the expertise of prof. dr. Ozer Ciftcioglu in the field of soft computing was crucial for tool development. By combining knowledge from two different disciplines a unique tool could be developed that would enable intelligent modeling of soft data needed for support of the building design process. In this respect, this research is a starting point in that direction. It is multidisciplinary and on the cutting edge between the field of Architecture and the field of Artificial Intelligence. From the architectural viewpoint, the perception of space is considered through relationship between a human being and a built environment. Techniques from the field of Artificial Intelligence are employed to model that relationship. Such an efficient combination of two disciplines makes it possible to extend our knowledge boundaries in the field of architecture and improve design quality. With additional techniques, meta know/edge, or in other words "knowledge about knowledge", can be created. Such techniques involve sensitivity analysis, which determines the amount of dependency of the output of a model (comfort and public safety) on the information fed into the model (input). Another technique is functional relationship modeling between aspects, which is derivation of dependency of a design parameter as a function of user's perceptions. With this technique, it is possible to determine functional relationships between dependent and independent variables. This thesis is a contribution to better understanding of users' perception of underground space, through the prism of public safety and comfort, which was achieved by means of intelligent knowledge modeling. In this respect, this thesis demonstrated an application of ICT (Information and Communication Technology) as a partner in the building design process by employing advanced modeling techniques. The method explained throughout this work is very generic and is possible to apply to not only different areas of architectural design, but also to other domains that involve qualitative data.

summary Bases de datos, Sistemas y Redes 134The purpose of this report is to present the achievements obtained in the use of the technologies of information andcommunication in the architecture, by means of the construction of a database to register the information on the modernarchitecture of the city of Maracaibo from 1920 until 1990, in reference to the constructions located in 5 of Julio, Sectorand to the most outstanding planners for its work, by means of the representation of the same ones in digital format.The objective of this investigation it was to elaborate a database for the registration of the information on the modernarchitecture in the period 1920-1990 of Maracaibo, by means of the design of an automated tool to organize the it datesrelated with the buildings, parcels and planners of the city. The investigation was carried out considering three methodologicalmoments: a) Gathering and classification of the information of the buildings and planners of the modern architectureto elaborate the databases, b) Design of the databases for the organization of the information and c) Design ofthe consultations, information, reports and the beginning menu. For the prosecution of the data files were generated inprograms attended by such computer as: AutoCAD R14 and 2000, Microsoft Word, Microsoft PowerPoint and MicrosoftAccess 2000, CorelDRAW V9.0 and Corel PHOTOPAINT V9.0.The investigation is related with the work developed in the class of Graphic Calculation II, belonging to the Departmentof Communication of the School of Architecture of the Faculty of Architecture and Design of The University of the Zulia(FADLUZ), carried out from the year 1999, using part of the obtained information of the works of the students generatedby means of the CAD systems for the representation in three dimensions of constructions with historical relevance in themodern architecture of Maracaibo, which are classified in the work of The Other City, generating different types ofisometric views, perspectives, representations photorealistics, plants and facades, among others.In what concerns to the thematic of this investigation, previous antecedents are ignored in our environment, and beingthe first time that incorporates the digital graph applied to the work carried out by the architects of “The Other City, thegenesis of the oil city of Maracaibo” carried out in the year 1994; of there the value of this research the field of thearchitecture and computer science. To point out that databases exist in the architecture field fits and of the design, alsoweb sites with information has more than enough architects and architecture works (Montagu, 1999).In The University of the Zulia, specifically in the Faculty of Architecture and Design, they have been carried out twoworks related with the thematic one of database, specifically in the years 1995 and 1996, in the first one a system wasdesigned to visualize, to classify and to analyze from the architectural point of view some historical buildings of Maracaiboand in the second an automated system of documental information was generated on the goods properties built insidethe urban area of Maracaibo. In the world environment it stands out the first database developed in Argentina, it is the database of the Modern andContemporary Architecture “Datarq 2000” elaborated by the Prof. Arturo Montagú of the University of Buenos Aires. The general objective of this work it was the use of new technologies for the prosecution in Architecture and Design (MONTAGU, Ob.cit). In the database, he intends to incorporate a complementary methodology and alternative of use of the informationthat habitually is used in the teaching of the architecture. When concluding this investigation, it was achieved: 1) analysis of projects of modern architecture, of which some form part of the historical patrimony of Maracaibo; 2) organized registrations of type text: historical, formal, space and technical data, and graph: you plant, facades, perspectives, pictures, among other, of the Moments of the Architecture of the Modernity in the city, general data and more excellent characteristics of the constructions, and general data of the Planners with their more important works, besides information on the parcels where the constructions are located, 3)construction in digital format and development of representations photorealistics of architecture projects already built. It is excellent to highlight the importance in the use of the Technologies of Information and Communication in this investigation, since it will allow to incorporate to the means digital part of the information of the modern architecturalconstructions that characterized the city of Maracaibo at the end of the XX century, and that in the last decades they have suffered changes, some of them have disappeared, destroying leaves of the modern historical patrimony of the city; therefore, the necessity arises of to register and to systematize in digital format the graphic information of those constructions. Also, to demonstrate the importance of the use of the computer and of the computer science in the representation and compression of the buildings of the modern architecture, to inclination texts, images, mapping, models in 3D and information organized in databases, and the relevance of the work from the pedagogic point of view,since it will be able to be used in the dictation of computer science classes and history in the teaching of the University studies of third level, allowing the learning with the use in new ways of transmission of the knowledge starting from the visual information on the part of the students in the elaboration of models in three dimensions or electronic scalemodels, also of the modern architecture and in a future to serve as support material for virtual recoveries of some buildings that at the present time they don’t exist or they are almost destroyed. In synthesis, the investigation will allow to know and to register the architecture of Maracaibo in this last decade, which arises under the parameters of the modernity and that through its organization and visualization in digital format, it will allow to the students, professors and interested in knowing it in a quicker and more efficient way, constituting a contribution to theteaching in the history area and calculation. Also, it can be of a lot of utility for the development of future investigation projects related with the thematic one and restoration of buildings of the modernity in Maracaibo.

title Fabrication with Residual Wood through Scanning Optimization and Robotic Milling

summary The project deals with the use of residual wood of tree stumps and roots through scanning, optimization and robotic milling. Wood logging residue makes up to 50 percent of the trees harvested biomass. (Hakkila and Parikka 2002). Among prevailing strategies is leaving residue on site, and recovering residue for bioenergy. (Perlack and others 2005). The project explores the third strategy, using parts of the logging residue for fabrication, which may reduce the overall amount of wood logging volume. Furthermore approach aims for applying residue in its natural form and taking advantage of specific local characteristics of wood (Desch and Dinwoodie 1996). The project applies the strategy on working with stump and roots of an oak tree. Due to considerations of scale, available milling technics and available resources, chosen goal of the approach is to create a functioning chair prototype. Among the problems of the approach is the complex shape of the residue, uneven quality of wood, varying humidity and contamination with soil. After cleaning and drying, the stump is scanned and a 3D model is created. The 3D model od a stump is confronted with a 3D modelled limits of the goal typology (height, width, length, sitting surface area and overal volume of a chair) and topological optimization algorithm is used to iteratively reach the desired geometry. Unlike in established topological optimization proces, which aims for a minimal volume, the project attempts to achieve required qualities with removing minimal amount of wood. Due to geometric complexity of both stump and goal object, milling with an 6axis industrial robotic arm and a rotary table was chosen as a fabrication method. The object was clamped to the board (then connected to a rotary table) in order to provide precise location and orientation in 3D space. The milling of the object was divided in two parts, with the seating area milled in higher detail. Overall process of working with a residual wood that has potential to be both effective and present aesthetic quality based on individual characteristics of wood. Further development can integrate a generative tool which would streamline the design and fabrication proces further.

title Road hierarchy and speed limits in Brasília/Brazil

summary This paper aims at exploring the theory of the Social Logic of Space or Space Syntax as a strategy to define parameters of road hierarchy and, if this use is found possible, to establish maximum speeds allowed in the transportation system of Brasília, the capital city of Brazil. Space Syntax – a theory developed by Hillier and Hanson (1984) – incorporates the space topological relationships, considering the city shape and its influence in the distribution of movements within the space. The theory’s axiality method – used in this study – analyses the accessibility to the street network relationships, by means of the system’s integration, one of its explicative variables in terms of copresence, or potential co-existence between the through-passing movements of people and vehicles (Hillier, 1996). One of the most used concepts of Space Syntax in the integration, which represents the potential flow generation in the road axes and is the focus of this paper. It is believed there is a strong correlation between urban space-form configuration and the way flows and movements are distributed in the city, considering nodes articulations and the topological location of segments and streets in the grid (Holanda, 2002; Medeiros, 2006). For urban transportation studies, traffic-related problems are often investigated and simulated by assignment models – well-established in traffic studies. Space Syntax, on the other hand, is a tool with few applications in transport (Barros, 2006; Barros et al, 2007), an area where configurational models are considered to present inconsistencies when used in transportation (cf. Cybis et al, 1996). Although this is true in some cases, it should not be generalized. Therefore, in order to simulate and evaluate Space Syntax for the traffic approach, the city of Brasília was used as a case study. The reason for the choice was the fact the capital of Brazil is a masterpiece of modern urban design and presents a unique urban layout based on an axial grid system considering several express and arterial long roads, each one with 3 to 6 lanes,

summary Natural visual landscape is under deterioration due to improper construction and planning in modern development of China. One of the main reasons is the feebleness in planning supporting methodology and technology in respect for natural visual landscape. In such supporting information, landscape evaluation always acts as a significant component. Especially in comprehensive planning, it is the only approach to access visual value distribution in large-scale region. In this paper, we present a GISbased natural visual landscape evaluation tool through a case study. By an integrated rating statistics function of this tool, visual quality of natural landscape is quantified through analysis in visibility, landuse, and visual resource quality. Then we make comprehensive planning strategies based on this scientific supporting tool. Furthermore, we discuss the potential of this tool by comparing these strategies with schemes of the same project conducted through traditional planning module. This comparative study reveals the efficiency and effectiveness of the tool as well as its implementation in large-scale comprehensive urban planning.

title Auto-Generative Urban Interventions: A Study of the Relationship between Building Form Generation and Urban Context Mapping
source SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 297-298
summary This project documents the progress of research developed to explore the unique relationship between building form and urban context with the application of a novel auto-generative modeling process incorporated into a speculative design methodology. The techniques and parameters for the project are reviewed relative to key concepts of D’Arcy Thompson’s dynamic “theory of transformation” and the development of the auto-generative modeling process. This is followed by a detailed discussion of the set of exchanges between the urban context (field of influence) and the formation of the building intervention that were subsequently mappedthrough a series of diagramming studies. Specific issues explored in the project focus on Thompson’s descriptive analysis of form as a “diagram of forces” and his use of flexible, deformable topological Cartesian nets (Method of Coordinates) to subject the stasis of geometric types to dynamic transformation. Some preliminary interpretations of the project results are evaluated through studies of the generative schemes deployed in different urban situations. The initial results of the study are demonstrated with a resultant schematic building design for a modest scaled intervention in the city of Miami.

doi https://doi.org/10.52842/conf.ecaade.2002.140
source Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 140-143
summary Design Computing is an interdisciplinary field that centres on the intersection of design, computer science and linguistics. This multidimensional face of the new paradigm of design computing necessitates a mutual understanding of computing and designs as a whole, which are usually, conceived as separated stages of computed-mediated design. Based on cognitive and computational approach, with the integration of scaffolding strategies and multiple representations, an interactive and real-time design computing learning system is constructed. By interactively manipulating the various attributes, codes, parameters and digital media contents in a distributed system, learners are gradually exposed to the mutual relationship of representational digital multimedia and the underlining programming syntax in a collaborative environment. The author attempted the use of game programming technology in the development of the above system to support design learning and research in understanding design activities. The aim is to identify the design process that if taught well would address the core goals of design education.

title Use of Cadastral Data for the Development of Spatial Decision Support Systemsfor Coping with the Consequences of Natural Disasters
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings Avegoor, the Netherlands), 2002
summary This paper investigates the potential usefulness of cadastral data to form the core part of databases of Spatial Decision Support Systems [SDSS] that are capable to support decision-makers in dealing with emergency situations, such as earthquakes, floods and fires. Particular emphasis is given on how those data can be used to generate information that is necessary to planners and decision-makers when they cope with natural disasters at every stage of the development of the disaster: before the occurrence (planning and preventive measures), immediately after occurrence (short term measures), and well-after occurrence (medium and long term measures). This investigation is conducted using the Municipality of Magoula, Attica, Greece, as a case study area. This municipality is situated in the greater Athens area and was struck by the earthquake that occurred there in September 1999. Within the scope of the project, wehave used cadastral data about the study area and data recorded by the inspection teams in order to set-up a prototype SDSS database that could facilitate planning and decision-making in such a situation. Then, we have used that prototype to generate scenarios and information about typical tasks that are performed during emergency situations. The advantages that are realized from the integration of such data and information technologies are described and assessed, particularly, in comparison with the traditional approaches that are used in such situations.

title A Study of the Accuracy of Daylighting Simulation of Heavily Obstructed Buildings in the Urban Canyons of Athens
doi https://doi.org/10.52842/conf.ecaade.2002.456
source Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 456-463
summary This paper deals with the use and evaluation of daylighting simulation tools in relation to a complex urban environment. The environment concerned is one commonly found in city centre areas where the proximity of buildings leads to the creation of ‘urban canyons’; the result of this is that assessment and simulation of daylight requires a more sophisticated approach than for other situations. In urban areas building layout is the most important factor effecting daylight, sunlight and solar heat gain reaching a building. It also affects sunlight in open spaces, ventilation, shelter and the dispersal of pollutants. In order to produce a more realistic understanding of the dynamic effects of daylight, there is a need not only for the research and development of advanced CAD and lighting simulation tools, but also of the study of possible alternative methods in their application. In the work reported in this paper, an attempt has been made to move the focus of lighting and daylighting simulation from the scale of a room to that of a whole building; the building itself being surrounded by its specific urban environment (including its microclimate). The study evaluates if there is sufficient evidence that it is possible with such complexity to reach reliable computation results after executing the simulation. The case study presented uses a 4D model of an urban canyon to investigate the sensitivity of such a complex simulation system. It can also be used to find ways to analyse and predict how daylight is reflected, refracted, scattered, diffused, polarised, diffracted and absorbed as it traverses an urban environment.
