“…All documents collected have been redrawn by us with CAD tools in order to attain the highest level of objectivity, homogeneous graphic display criteria and the same level of detail, without taking textures into account (Ostwald and Vaughan 2013), using black color and line width *0.00 mm (that is, the minimal lineweight allowed using CAD software), see Fig. 4.…”

“…Specifically, those authors looked for a relation between the structure of the architects' constructions and the natural or artificial environment where those constructions were projected. These techniques have also been used in other kinds of architectural studies (see Bovill 1996;Eglash 1999;Batty and Longley 2001;Burkle-Elizondo 2001;Ostwald 2001Ostwald , 2010Crompton 2002;Brown and Witschey 2003;Cooper 2003;Sala 2006;Hammer 2006;Joye 2007;Rian et al 2007;Bovill 2008;Ostwald and Vaughan 2013). These works are based on a geometrical concept which is called fractal dimension.…”

The classic patterns of Euclidean Geometry were used in the construction of the Gothic cathedrals to provide them with proportion and beauty. Still, there is also another complex concept related to them: the un-evenness of their structures, which determines their space-filling ability, that is, their level of roughness. In this paper we use the techniques of Fractal Geometry to generate parameters which provide a measure of roughness. In this way we show that the French Gothic cathedrals do not only follow Euclidean geometric patterns, but also have a general non-random fractal pattern.

“…The representation chosen should also be clearly documented and reasoned. A framework to assist in this matter has been developed with five cumulative levels of representation identified (Ostwald and Vaughan 2013). Each level could be conceptualized as an overlay on the one before; thus Level 3 representation assumes that Levels 1 and 2 are already included and visible in the image (Table 1).…”

In architectural research, debates about the development, function, or appropriateness of building forms have traditionally been dominated by qualitative approaches. These have been common in the past because the full geometric complexity of a building has proven difficult to encapsulate in any single measurement system. Even simple buildings may be made up of many thousands of separate changes in geometry, which combine together across multiple scales to create a habitable or functional structure. However, since the 1990s architectural scholars have begun to adopt one particular method for mathematically examin

“…Further works in other disciplines including geography, landscape and urban planning and architecture investigated links between fractal geometry and built environment in macro and micro scales (Liang et al, 2013). Fractal analysis of built environment is one of the most widely used methods for quantification of visual properties (Vaughan and Ostwald, 2013).…”

Measuring visual attributes for assessing visual conflicts in urban environments

The visual relationships between a proposed development and the existing urban setting have become increasingly controversial in the past two decades. Protecting and enhancing visual attributes of the current urban environment is regulated by a range of performance-based policies and regulations. However, every year many development conflicts occur between developers, local councils and residents resulting in costly delays in the development process. Visual amenity and character are two of the most contentious issues in these conflicts.Currently, conflict resolution based on these policies relies on experts' interpretation of what appears to be visually significant. Although visual amenity experts aim to provide an impartial and objective assessment of visual effects of proposed developments, their evaluations are sometimes mixed with personal judgments and lack enough centrality and reliability. The problem is compounded by the fact that there are no consistent approaches within and between localities and experts as to what is considered visually significant. The uncertainties and inefficiencies created by performance-based planning policies, to regulate the protection of urban visual quality, highlights the importance of developing reliable, measurable and repeatable approaches to analyse visual environments and to describe the urban character.Based on a postpositivist approach, a range of research methods using exploratory and descriptive approaches was used to answer the stated research questions. Therefore, the research design is split into three stages. The first stage involved reviewing the planning court cases in Brisbane from 2000 to 2012 to identify the overall different types of conflicts within the city. These conflicts were analysed spatially to determine their distribution and to look for any significant spatial patterns. Based on this review, four case studies were selected, and three measurable methods were developed to provide a higher level of quantitative assessment of visual properties of the urban character. In the last stage, the technical methods were evaluated by a panel of three visual amenity expert witnesses to investigate the effectiveness, usefulness and potential of these methods to be applied in expert assessments and court case resolutions.This research focuses on urban visual amenity conflicts in the city of Brisbane, Queensland, Australia and identifies the gaps and recurring issues inherent in expert assessments and judgments. Based on this knowledge, quantitative methods to assess visual amenity and character, with greater objectivity and reliability than existing methods, have been developed. The outcome of this research contributes to the field of visual assessment and character studies in landscape planning and assists decision makers and Environmental and Planning Courts to determine development conflicts with more objectivity and reliability.
