Thesis (Ph.D.)--The Chinese University of Hong Kong (Hong Kong), 2016.

In this thesis, the author has explored the feasibility of 3D visibility analysis for visual quality assessment via the aid of modelling tools, virtual geographic environment (VGE) and WebGIS, which may be beneficial to build a measurable evaluating standard of visual environment in urban open spaces, and referential to create an atmosphere with improved visual comfort in guiding planning or design processing. Considered as long-term significance, 3D visibility analysis for visual quality assessment is potential in enabling the quantitative analysis between urban open spaces and visual perception of human, providing appropriate standard for evaluation of visual environment, and bringing the future urban planning and design fields into rational and reasonable.

520 $a In this thesis, the author has explored the feasibility of 3D visibility analysis for visual quality assessment via the aid of modelling tools, virtual geographic environment (VGE) and WebGIS, which may be beneficial to build a measurable evaluating standard of visual environment in urban open spaces, and referential to create an atmosphere with improved visual comfort in guiding planning or design processing. Considered as long-term significance, 3D visibility analysis for visual quality assessment is potential in enabling the quantitative analysis between urban open spaces and visual perception of human, providing appropriate standard for evaluation of visual environment, and bringing the future urban planning and design fields into rational and reasonable.
520 $a Due to the development of 3D modelling software and VGE, their applications have been attempted in 3D visibility analysis by a few previous scholars, exploring the possibility of representation for urban environment in 3D and the feasibility of spatial relationship analysis with visual factors. Lots of progress has been made with the participation of the modelling software such as AutoCAD and 3Ds Max, or analytical platforms such as ArcGIS and VGE. As the extension of preceding study, the author is going to discuss improvements and innovations of some tools applied in visibility analysis and visual quality computation, such as Open Simulator as a VGE Platform. Moreover, due to the easy access for entry-level programmer and the public, Google SketchUp (a type of modelling software) and WebGIS have also been tested whether suitable for the analysis handling, considerably decreasing the programming development difficulty. Both SketchUp and WebGIS are thought to be well accepted by the public, as SketchUp has been popularised in 3D modelling and WebGIS has been familiar as the form of websites for a long period, which may enable the dissemination of visibility analysis to the public.
520 $a From a pilot study of progresses based on the researches of past scholars, the author developed an improved method for 3D visibility analysis, by mathematically deriving the visual factors from the spatial relationship analysis of buildings, terrain and other geographical features. A few quantitative factors as the distance, solid angle and visual field (a distribution of occupied solid angle in all directions) valued in spherical coordinate system were adopted as the basic units for visibility levels. Starting from the space prototype, the research has also focused on several aspects possibly associated to the visual effects in open spaces, including the openness, enclosure and ground coverage for edge, the distribution and dispersion for skyline, and the visibility of individual building for landmark. For further comparison, the variances of those figures were also noticed during space scales changing for the prototype, in order to find possible connection or changing trend before and after. Moreover, experiments of 3D visibility analysis have been designed and put into practice for real scenes to discover the similarities or differences among prototypical spaces and reality, and Piazza del Campo (Siena, Italy), Piazza San Marco (Venice, Italy) and Olomouc centre area (Olomouc, Czech) have been selected as the first group of candidates. As a complementary study, the central campus area of the Chinese University of Hong Kong (CUHK) were also taken into consideration as an experimental site, for comparison of disparities with those classical scenes. Those would be possible references for conclusion of similarity or discrepancy among various spaces, in order to find out spatial general pattern, or reveal the actual affections of visual factor values in the reality.
