The objective of this study was to examine the possibility of utilizing the immersion stereoscopic image with a curved-screen-display as a tool for evaluating the landscape. The curved-screen-display ensures the continuity of the image and can be simultaneously evaluated by many people. Fifty-meter-wide Gangnamdaero Boulevard in Seoul was selected for this study, and the simulation was done using computer graphics. With the computer simulation, a questionnaire on landscape preferences was conducted according to different visual environments (immersion, non-immersion) and different projection types(stereoscopic or plane image). In the results of this study, the landscape preference was largely dependent on the immersion environment. Using the immersion-type simulation, the observer can easily evaluate the preference with higher judgment power. The stereoscope or plane projection type does not have any significant result in terms of its judgment power. This result implies that it is very important to strengthen the sense of immersion by expanding the screen into an angled view in which the observer can become immersed while making and projecting the simulation to evaluate the landscape. As a landscape evaluation tool for examining the efficiency and usefulness of immersion simulation, this study has limitations in that it controls many factors in street landscape that adversely affect judgment. Accordingly, a detailed comparison and verification of the stereoscopic image in various environments, including street width and building height ratio, must be conducted.

야간 경관조명을 계획 및 평가하는데 필요한 물리량의 측정기법이나 컴퓨터 시뮬레이션의 유효성에 대한 검증이 미흡한 상황이다. 이에 본 연구 경관조명에 많이 사용되는 대표적 프로그램인 Lightscape 3.2의 유효성을 Radiant Imaging ProMetric 1400을 이용하여 검증한 것이다. 교량의 7개 부분에 대한 평균 휘도값을 비교한 결과 Radiant Imaging ProMetric 1400에 의한 물리량 측정값과 Lightscape 3.2의 컴퓨터 시뮬레이션 값 사이에는 상대오차율이 평균 8.3%로 나타나, Lightscape 3.2가 경관조명의 사전 시뮬레이션 도구로써 매우 유효한 것으로 나타났다.

The purpose of this study is to determine the evaluation of affected visual landscape of Taereung National Training Center to Taereung and Gangneung UNESCO World heritages, South Korea. For this research, it used to offer the affected visual landscape rate and 3D simulation with Sketch up 8.0. This study conducted over 4 steps. Step 1, view points are selected with literature review and interview. Step 2, with Sketch up created 3D modelling and calculated the affected rate on the landscape. Step 3 individual buildings were mapped with the affected rate. Lastly, step 4 were identified the results through field research. From this results, the visual landscape of Taereung and Gangneung that are damaged by the Taereung National Training Center did not appear higher than initially expected. The entrance area on Gangneung, however, where is affected from Oryungwan, Korea Sports Institute, Philseung Gym needs to establish a way to improve that landscape impact. In case of Taereung, it did not appear damaged due to the hiding effect of the forest. By field survey to confirm those results, it shows seasonal differences. In the case of the summer and autumn derive similar results with 3D simulation but were exposed buildings in the winter and spring. It means when the simulation based on the summer and fall operates, it may not reflect the affected landscape of certain times such as winter and spring. This study has significance as a basic research to co-exist between the traditional heritage and modern heritage.

Adverse effects resulting from the development of the environment and to minimize damage to the natural environment and the desire for pleasant scenery and the sense of raising more awareness about May 17, 2007 in accordance with the scenery method is established by each municipality landscape management and landscape planning committee Configure the district planning officer for development projects, including enhancing deliberation scenery method 7 February 2014 and revised in urban areas is more than $30,000m^2$ urban planning landscape projects are all considered by a committee mandated to landscape receive a defined landscape plan for the development was enhanced. Gyeonggi Province in 2007 after the enactment of the scenery method for district planning and landscape planning by strengthening the district planning consideration during deliberations landscape simulation by selecting the view that the proposed mandatory hearing officer from the Joint Committee on Urban construction was done. In this study, Gyeonggi-do district planning business point of view the characteristics of the landscape planning and landscape planning of the center of analysis and as a basis for the evaluation presented.

By preservation of vegetation landscape in urban park, the uniqueness and attractiveness of a city can be created and maintained. In this study, the CAD simulation of Dwangju Park was implemented, and it was proved that CAD simulation can be used to preserve the vegetation landscape and to regulate the building construction. But, when simulated short range vegetation landscape, such as the position, height and forms of trees, vegetation structure, dtc., are can be important factors. And, the method of suveying and presenting trees in CAD for efficient simulation are need to be sutdied futher.

After Landscape Act was enacted, as awareness of landscape has increased and the need of expanding targets of landscape design review and improving landscape examination in terms of quality, this study aims to describe a technique of creating three dimensional landscape simulation model which is used for landscape design review. For this, the author of this study conducted analysis in terms of function and use of programs and compatibility with programs to find a way of creating models with the most efficient and optimum process. For creation of landscape simulation models, initial creation is important but in case that changes occur by operator changing or discussing development plans, rapid correction and change are needed. Therefore, this study described how to build more accrurate and efficient simulation at initial review and how to create a landscape simulation model for rapid response to changed plans during reconsideration.

The study is to probe a technical alternative to enhance the reliability and accuracy of the results of various landscape simulations. This study to present technical criteria that are necessary in each stage of target site analysis, picture taking, and computer synthesis and, through these to present supplementary plans to enhance the reliability and accuracy of landscape simulations. In order to derive more practical and empirical results in terms of the reliability of the results of landscape simulations, examples that actually passed landscape review were selected. With regard to study process, an analysis was made first to analyze the landscape report data of designs that passed the review to analyze their characteristics, to be followed by an integrated analysis of problems that were revealed in various landscape simulations. Important factors that affect directly the work of landscape simulations such as the specification of camera lenses that were used in picture taking, distance, and angle. Design the work was carried out using Auto CAD, 3DS Max, and Photoshop program in the same way as in actual design. For verification of their accuracy and reliability, the results were entrusted to experts who have implemented similar jobs. To seduce differences from those too landscape simulations that conduct trial experiment of the virtual space that are to be created in the future with accurate numerical values.
