| Abstract |
Following the improvement of citizens’ level of consciousness and changing desire into environment-friendly residence thanks to increasing income and advancement, people’s interest is more focused on pleasant urban environment and urban development in the way of protecting its landscape. From this respect, the current broad and uniform legal system that controls residential environment and landscape is criticized to have a weak point in that it is difficult to implement flexible regulation in consideration of regional and locational properties. In addition, the discussion with public society would be impossible without quantitative index, and therefore the simulation of feasible analysis of blockage ratio is very important. History on the studies on preservation of landscape has lasted long up to now, and furthermore they are increasingly applied to the practice. Nevertheless, as most of them consist of two-dimensional analysis based on elevation, a lot of problems are exposed in the reality of Korea that has complex structure topographically. In addition, it lacks in efficiency with a uniform analysis methodology without any consideration of key landscape elements, and even difficult to be developed into the computed model, and therefore has a limit that it may not be applied in urban information system(GIS) too. Under this situation, this study is aimed at suggesting the method of quantifying urban landscape in three-dimensional way using 3-D simulation and then grasping its effectiveness by comparing it with the existing blockage ratio calculation algorithm. In analyzing this, 3-D virtual model was adopted, where the frequency of visual access between observational path and the node on Sky dome was checked, and then analysis methodology was set up as to how the visual pattern derived from this influence on the controlled landscape. In this way, four simulated alternatives having same gross floor area (floor area ratio) on the same land were suggested and analyzed, and the results were compared with the existing blockage ratio index to evaluate the effectiveness of this analysis methodology. |
