The purpose of this study is to propose a simulation approach which compares lighting quality of each luminaire type for small urban park users' safety. For improving illumination quality, lighting intensity distribution of a luminaire is one of the important factors and it is also important to set the luminaire to a proper position. To achieve the best plan for illumination, it is most important to communicate the plan with designers of park and professional engineers in depth and the communication continues from the beginning of the plan.

The purposes of this study were to develope some techniques which can be used in the landscape simulation process using PC based computer grahics. As a result, a couple of utilities were programmed in AutoLISP language. The one(DSLINE.LSP) is to digitize 2-dimensional structuer forms in the interactive mode considering error handling, and the other one (IMPOST.LSP) is for superimposing and visualizing the digitized plan data to 3-dimension solids & surfaces referring to topographic elevations of meshes in digital terrain model. By applying utilities to present site, the followings may be described. 1) The utility DSLINE.LSP for digitizing simplified building structure form were proved to be easy to input data of polygons including orthogonal edges by handling user coordinates system and checking invalid intersection and default colsing. 2) IMPOST.LSP utility for superimposing and visualizing tool were proved to be more complicated and speedy in calculating process compared with a practical application of modeling tool before rendering process in landscape simulation of built environment on topographic relief, on specially mesospace level of assessment.

In 2007, Google has introduced a novel approach to model some cities from around the world by utilizing vast amount of information provided by internet users. They essentially built an efficient engine to collect and compile enormous stream of data that are necessary to reproduce fine details of a city. In this Letter, we propose an implementation of this novel approach to establish a Web-based visualization of rural landscape and scenery. We later demonstrate its feasibility by constructing a 3D model of Namsa-ri, Danseong-myeon, Sancheong-gun, Gyeongsangnam-do.

As recent interest in ecological resources increases, an effort in three-dimensional visualization of the ecological resources has increased for the restoration and preservation of the natural environment as well as the evaluation of the landscape. However, in the case of forest resources, information extraction has been active, but the effort in trying to apply that information into an effective visualization has not happened. In other words, the effort for effective visualization is lacking when it comes to the visualization of forest resources, and numerous cases are ether non-realistic or the simulation required for analysis is inappropriate. Therefore, this paper extracts information through the use of airborne LiDAR data, aerial photograph, and forest type maps to create a vegetation layer, and then uses Flora3D forest modeling tools and ArcGlobe to accurately visualize the vegetation layer into the three dimension. An effective application for restoration and preservation of ecological resources as well as analysis on the urban landscape can be considered as a result of intuitively and realistically enabling the user's awareness of forest information within the Geographic Information System.

The objective of this study is to propose a color plan for rural villages that seeks harmony between natural and artificial environments in consideration of the fact that as new and renewable energy businesses increase drastically, problems of landscape color occur in rural areas. To this end, the current color conditions over the target regions are examined in context of energy businesses; a land simulation is developed; a survey on the preferences is conducted with the result analyzed; and finally, a color plan for villages where energy businesses and non-energy businesses are conducted. For the survey, 40 photos including simulation photos and original photos of villages were used: the photos before and after the simulation was applied were shown to village residents. The validity of the selected colors was then evaluated accordingly. The survey was conducted among 15 residents in villages where energy businesses were conducted and 15 in villages where non-energy businesses were conducted. As new and renewable energy methods such as solar energy panels are utilized over rural villages in the future, selecting artificial environmental colors that can better represent the region's identity and that are in harmony with natural environments will be an important factor in community center or housing remodeling projects, local community development projects, and so forth. It is expected that the present study can be utilized as the basis for village color plans that seek to consider actual local conditions based on objective data rather than selecting colors uniformly or based on subjective judgment.

This study saw developed to build a landscape monitoring methodology by simulation of landscape effect prediction. A Visual landscape planning and management system has been introduced and implemented by each ministry so as to solve the problems of visual landscape destruction due to recognition on the value of natural landscape of beautiful territory and various development projects. At present, this system emphasizes the importance of the visual and perceptual aspect of the landscape however, there is a lack of techniques required for comprehensively predicting, evaluating, and managing it. Furthermore, sustainable landscape management after the completion of development projects has been inadequately carried out, as the focus has been only on consultation in the planning process of the development project in institutional performance. The viewpoint for judging the change in the visual landscape of the development plan and development project should be selected as the effective point where the development project is expected to result in a remarkable landscape change. As for the method of selecting effective viewpoints, the main viewpoints are selected by analyzing the visible area of the target viewpoint. When selecting the viewpoint centered on the viewpoint target, it was judged that it is possible to reduce the procedure of selecting and checking the existing preliminary viewpoints and widening the effective visible range. The proposed visual landscape monitoring is expected to be able to solve the existing institutional problems, and to be used when the implementers and authors of the development projects review the effects on the landscape.

In drafting the standards on changes in current conditions, the height or the number of stories is applied in a restrictive manner by limiting to securing the distance to vertical surface for cultural properties within the influence investigation area, but this is expected to have a negative impact on the surrounding sceneries as well as results in the dwarfing phenomenon for precious cultural properties. That is, the preparation for supplementing the insufficient objectivity that is likely to take place during the process of drafting the standards on changes in current conditions. Thus the author attempts to suggest the analytic method for the decision making related to objective and reasonable determination and regulation of the changes in current conditions through computer based simulation work that considers the cultural properties and surrounding environments under investigation. In order to achieve such research objectives, the author reviewed the subject sites where the cultural property dwarfing phenomenon was expected to occur in case of the permission for the changes in current conditions or where the impact of natural landscape and natural feature on the earth is less than architectural building or artificial structure or where the new policy program is likely to be adopted due to incomplete establishment of current condition change standard within influence investigation area, among other cultural properties with architectural building or artificial structure nearby located in Cheonan city and then selected Cheonansaji Dangganjiju(flag poles) and Jiksanhyun Gwana(government office). The author then undertook the quantitative visibility analysis in order to determine the comprehensive prospect rights for the cultural properties and surrounding environments concerned.
