  • This study aimed at establishing the multi-ranged approach on data acquisition technique for rural landscape planning, which tried categorization, grading and transferring of landscape elements in the more detailed level. For the systematic management of database for the topographic informations in the village level, a kind of the aerial photographing techniques with UAV(Unmanned Aerial Vehicle) was used and its resultant data for the landscape simulation of the rural village, which in turn helped the convenient approach to understanding of its comprehensive spatial structure. The image data from aerial photography was systematically processed through; First, after revision of the distorted one, the image map was adjusted with the topographical and cadastral maps. Second, the farm houses and buildings, and other facilities difficult to find out in the topographical map was digitally read from the adjusted image. The topographical landscape view of rural village was simulated on the base of DEM(Digital Elevation Model) and the 3-dimensional shapes of farm houses and buildings were automatically modelled using the input system developed by the author. In conclusion, the aerial image information adjusted with the edited maps could give more intuitive and detailed villagescape than the ordinary one and through landscape simulation of the rural village, its topography, features of houses/buildings and spatial distribution of land uses were effectively reproduced. And, by the linkage between field survey and photographed/simulated results of the typical landscape elements using hyper-link method, it would be expected to develop as an effective visualization technique of rural landscape.

  • The purpose of this study is to suggest objective basic data for environmental resource planning through the evaluation of the visual quality by GIS. For this, Landscape information system have been made up of topographical and superficial information and landscape values of Cheju Island have been evaluated by using Grass 4.1, degree of visual preferences have been measured mainly by questionnaires and finally these data have been analyzed by using the correlation. Result of this study can be summarized as fellows, in the landscape value, remarkable views play a role as the dominant landscape information. Also, LCPs including various, successive view or a lot of visibility amount have high Landscape value. Therefore, it is important to management landscape which can preserve values of landscape elements through the creation of visibility area. In the visual preference, remarkable scenes play a part as a dominant factor. Also, LCPs including a wide field of vision or successive view have high visual preference. Therefore, it is proved that the visual preference is related to a field of vision and remarkable scenes. Finally, these data have been analyzed by using the regression, in order to verify the method. The result is that a R\sup 2\ is 0.715. It means that correlation is significant at the 0.01 level. In conclusion, the results of this study reveal that visual preference has been evaluated by aesthetic variables and landscape values have been evaluated by GIS. And visual preference and landscape values are closely correlated. In other words, it is possible to evaluate the aesthetic value by physical variable. The method of evaluationi is used in Cheju Island, and it will be possible to apply this method to other places. And this method can be applied to other places by special quality and landscape informatioin system, made up of landscape elements. Also, it will be possible to keep up management and applicatioin that is evaluated by GIS and computer program. Recently, there is a tendency tat visual and aesthetic approach, based on planners' experiences and intuitioin is gradually changed to the scientific approach, based on a objective data. Therefore, it is important that the measuring system is based on objective data which are concerned with a special quality of landscape. It is also significant that the environmental planning is based on a spatial image of physical environment and major landscape elements.

  • The purpose of this study is to overview domestic and foreign trends in the study of the landscape evaluation through new framework of landscape evaluation studies. 108 studies on the landscape evaluation are summarized and categorized into theoretical studies, verification of theories, development of evaluation methods and applications in physical planning. Major theories in the landscape evaluation came from the psycho-physics, the evolutionary theory ann the cultural-learning theory, and were verified and applied into physical planning. Early experimental researches on landscape evaluation, based on psycho-physics, were focused on relatively simple responses to landscapes. But many studies have been gradually related to the evolutionary theory and the cultural learning theory, emphasizing biological and cultural effects on landscape evaluation. Especially, Appleton's Prospect-Refuge theory' and Kaplans' 'Information Processing model' have very strong influence in landscape evaluation. Relatively there have been many application researches in Korea, which tells there have been strong needs to solve pending practical problems caused by the rapid economic and social growth for several decades. Almost of applications in physical planning are focused on physical features of landscapes, but for more comprehensive landscape evaluation, many other factors such as cognitive and sociocultural variables should be integrated into the whole evaluation system. As a result of reviewing of landscape evaluation studies, I found the overall domestic and foreign trends and the necessity of more research on the applications in physical planning. Because this study mainly focused on academic researches, for more appropriate landscape evaluation and management there should be more practical researches including various approaches.

  • This study creates the LCP (Landscape Control Point) through the survey of spot sites for the quality of landscape assessment, which is based on an objective and departmentalized data base; the landscape assessment was achieved by production of weight value with the AHP (Analytic Hierarchy Process) technique, selection of requisites for the landscape assessment with the IVERSON method and visual area analysis with GIS (Geographic Information System). Futhermore, validity of the landscape assessment was verified by analysis of the correlation between physical amount and aesthetic amount. The purpose of this study is to suggest the basic essential data for landscape assessment and landscape planning by the characteristics of landscape based on verification of the suggested landscape assessment methods. The results of this study are summarized below. 1. In the adaptation of landscape assessment using GIS, the landscape assessment points of LCP 18, 17 and 16, which have more visible elements such as hill area, mountain area, and forest and farm land, were indicated to be higher than the others. In contrast, the landscape assessment points of LCP 13, 6 and 10, which have less visible elements, were relatively lower than the others. 2. In the visible preference measuring method, LCP 4, 14, and 16 showed high points of landscape assessment with 3.46, 3.4, and 3.18 each. With the more natural environments such as hill area, mountain area, and forest and farm land, higher results were shown. In contrast, LCP 7, 1, and 9 showed low points of landscape assessment with 2.24, 2.36, and 2.53 each. 3. In this study, a coefficient of 0.746 was gained by the analysis of correlation between the points of landscape assessment method and the points of visual preference from a slide show. This has 99 percent of probability in statistical data. 4. In conclusion, with the demonstration of the correlation between the landscape assessment method based on the AHP technique and the aesthetic amount (preference proportion), the practical use of landscape assessment can be demonstrated by the suggested landscape assessment method.

  • In this study, an integrated 3D modeling and rendering system dealing with 3D urban landscape features such as terrain, building, road and user-defined geometric ones was designed and implemented using $OPENGL\;{|}\;ES$ (Embedded System) API for mobile devices of PDA. In this system, the authoring functions are composed of several parts handling urban landscape features: vertex-based geometry modeling, editing and manipulating 3D landscape objects, generating geometrically complex type features with attributes for 3D objects, and texture mapping of complex types using image library. It is a kind of feature-based system, linked with 3D geo-based spatial feature attributes. As for the rendering process, some functions are provided: optimizing of integrated multiple 3D landscape objects, and rendering of texture-mapped 3D landscape objects. By the active-synchronized process among desktop system, OPENGL-based 3D visualization system, and mobile system, it is possible to transfer and disseminate 3D feature models through both systems. In this mobile 3D urban processing system, the main graphical user interface and core components is implemented under EVC 4.0 MFC and tested at PDA running on windows mobile and Pocket Pc. It is expected that the mobile 3D geo-spatial information systems supporting registration, modeling, and rendering functions can be effectively utilized for real time 3D urban planning and 3D mobile mapping on the site.

  • The purpose of this study is to investigate and compare the validity and the reliability of the visual simulation method using the internet. For this. the evaluation of the artificial and natural landscape through the medium of color slides are compared with the internet survey. Data is analysed through the comparison of t-test between the two media by landscape type, and spatial image is analysed by factor analysis algorithm. Principle component analysis using Varimax Method is applied for extraction and factor rotation respectively. The results of this study can be summarized as follows; There are no statistical differences between the two methods with artificial and natural landscape in the total data that included second tests. Factors covering the spatial image are found to be \`aesthetic\`, \`spatial shape\`, and \`familiarity\`. Total variance is obtained as 66.4%. There are no statistical differences between the two methods in 2/3 of the cases. In the case of far view of artificial landscape, the results of the t-test show that the two methods are exactly the same. Especially in the case of the artificial far landscape shows no difference of all factors between two methods. There are no differences between first and second tests of the same media and the same landscape type. And it shows the reliability of this method. These results suggest that the probability that the internet can be used as a medium of landscape evaluation and gathering information on anyone\`s landscape image. Simulation techniques with the internet survey method should be further developed for practical application.

  • 경관은 인간과 자연환경이 결합되어 시공간적으로 나타나는 토지 모자이크이며, 토지이용 및 지피(landcover)의 변화는 지역의 경관구조를 변화시키는 주요한 원인으로 인식되고 있다. 본 연구에서는 다양한 경관요소들이 존재하는 경산시를 대상으로 1985년과 1997년의 Landsat TM 영상을 통한 토지이용의 변화 및 경관지수를 사용하여 대상지역의 경관구조 변화에 대해 분석하고자 하였다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, 도시화로 인해 산림 및 농경지가 도시지역으로 전용되고 있는 것으로 나타났다. 둘째, 산림지역에서 개발로 인한 훼손으로 파편화 현상이 발생하여 산림의 건전성이 감소하고 있음을 알 수 있으며, 농경지를 중심으로 도시지역의 확장이 이루어지고 있는 것으로 판단된다. 셋째, 산림지역 주변의 토지이용형태가 농경지 중심에서 도시지역과 농경지의 혼합된 형태로 변하고 있음을 알 수 있다.
