Development of the Three Dimensional Landform Display Software Using the Digital Terrain Model
Journal of the Korean Institute of Landscape Architecture, volume 17, issue 3, 1990, Pages 1~8
The digital terrain model (DTM) or digital elevation model (DEM) is commonly used in representing the continuous variation of relief over space. One of the most frequent applications is to display the three dimensional view of the landform concerned. In this paper, the altitude matrices-regular grid cell format of the elevation in Mt. Kyeryong National Park were used in developing the three dimensional view software for the first time in Korea. It required the removal of hidden lines or surfaces. To do this, it was necessary to identify those surfaces and line segments that are visible and those that are invisible. Then, only the visible portions of the landform were displayed. The assumption that line segments are used to approximate contour surfaces by polygons was used in developing the three dimensional orthographic view. In order to remove hidden lines, the visibility test and masking algorithms were used. The software was developed in the engineering workstation, SUN 3/280 at the Institute of Space Science and Astronomy using 'C' in UNIX operating system. The software developed in this paper can be used in various fields. Some of them are as follows : (1) Landscape design and planning for identifying viewshed area(line of sight maps) (2) For planning the route selection and the facility location (3) Flight simulation for pilot training (4) Other landscape planning or civil engineering purposes
A Study on Cognitive Factors for the Landscape Preference
Journal of the Korean Institute of Landscape Architecture, volume 17, issue 3, 1990, Pages 9~20
The objective of this study is to test the applicability of the Information processing model suggested by Kaplan to the preferences of Korean people as well as to investigate the preference patterns of Korean people and the influencing factors on Korean preferences for the landscape. Photo - questionnaire survey was conducted twice to collect the data concerning the landscape preferences. The samples of the first survey were selected from the citizens of Seoul and the students of Seoul National University. The first survey focused on the preference patterns of Korean people while the emphasis of the second survey was given to the test of information processing model and the influencing factors on the preferences of Korean people. The samples of second survey were also selected from the students of Seoul National University. The photos in the photo - questionnaire for the first survey included the scenes representing both three landscape styles(Korean, Japanese and Western styles)and three landscape qualities such as the layout of space, the use of landscape plants and the use of stones and rocks. For the second survey, four informational factors such as complexity, coherence, legibility and mystery were selected for inclusion in the photos of photo - questionnaire. Respondents for both survey were asked to respond their preferences on the five - point Likers scale. The results of the study suggested that four informational factors influence significantly the preferences of Korean students. The study indicated that both the citizens of Seoul and the students of Seoul National University prefer water and vegetation to rock among the contents of landscape. Among the landscape styles, Japanese landscape style was most preferred and Western landscape style was more preferred than Korean traditional landscape style. In addition to informational factors, it was found that the contents of landscape and landscape style were also major influencing factors on the landscape preferences. The socio - economic backgrounds of respondents such as age, foreign travel experience, income, residency before the age 14, familiarity and respondent's experties in landscape architecture seemed to Influence the landscape preferences.
Use Impacts of Trail and Campsite on Natural Environments in Mt. Palgong Natural Park
Journal of the Korean Institute of Landscape Architecture, volume 17, issue 3, 1990, Pages 21~34
Trail and campground deteriorations and their environmental changes of soil and vegetation were studied in Tonghwa -Sa district of Mt. Palgong Natural Park through 1988 into 1989. The results are summarized as follows : 1. The bare width of trail as one of the trail condition factor was significantly greater on the more heavily used trail. Deterioration types of trail which had higher frequency for a total of 45 observations were rock exposure(42%), trail deepening(40%) and root exposure(18%) in the high order. And also sound type on which the trail was not deteriorated at all amounted to 33% of all observations. 2. Ecological changes of soil and vegatation of trailsides were not found at a uniform tendency except that soil hardness was slightly decreased from trail edge to the forest, but they could be grouped by the type of user\`s behavior and site conditions. Use impacts on the natural environment of trailside in Mt. Palgong are still far from the severe harmulness. 3. Worse damages to compground condition were appeared in Bawi-gol than Susu-gol campsite. Types of mechanically damaged trees were tree with exposed root(63% ), scared tree(43% ), mutilated tree(30 % ) and felled tree in highly frequent order. And diameter increments of trees in campsites were oppressed by the campers. 4. Tree damage types and their frequencies could be basic as a means of which grasp the bounds of user's impacts. User's disturbance on campsite extended to the distance of 70∼90m from the core of campsite at Pawi-gol and 20∼30m at Susu-gol respectively. As the tolerant trees to use impact, Lespedeza maximowiczii, Rhus trichocarpa, Acer palmatum, Rubus crataegifolius and Celastrus orbiculatus were considered.
Studios on the Vegetational Landscape Structure and Administration Planning of the Royal Tomb (II)-Successional Trends of the Plant Community of Heonin Royal Tomb-
Journal of the Korean Institute of Landscape Architecture, volume 17, issue 3, 1990, Pages 35~47
This study was executed to analyze the vegetational landscape structure and administration planning of Heonin Royal Tomb forest by three kinds of ordination techniques (PCA, RA and DCA) and comparison of the couple photographs between 1920s and 1980s. Seventeen sites in the recreation area and fifteen sites in the protective area were sampled with clumped sampling method in June 1988 and five quadrats were examined in each site. Environmental impact grade 3, 4 and 5 area covered 56.4% of the surveyed area and these area should be restored by the input of human energy. Pinus densifora community of actual vegetation covered 8.4%, Alnus japonica 24.2% and Quercus community 40.9% of the total area. And the afforested vegetation of Pinus koraiensis and Pinus rigida covered 23.1 % The recreation area was divided by P. densiflora, P. densiflora-Quercus aliena, A. japonica-Q.aliena, A. japonica and the protective area by Q. acutissima, Q. aliena, A. japonica-Q. aliena.. DCA ordination showed that successional trends of tree species seem to be from P. densiflora, Sorbus alnifolia, Styrax obassia to Q. variabilis Q. serrata in P. densiflora community and from A. japonica through A. ginnala to Q. aliena in A. japonica community of the upper layer. By the comparison of the couple photographs between 1920s and 1980s, we can recognize the change of historical landscape composed of P. densiflora community and those community is succeeded to Q. aliena.
A study on the second Intention of Taek-li-ji
Journal of the Korean Institute of Landscape Architecture, volume 17, issue 3, 1990, Pages 49~57
In general, Taek-li-ji is noted for its reliable source in studies on the old korean culture. But when we examine it in detail, we can find its contrary propositions with regard to the context ; for the thematic question of the good place to settle, that is the leitmotiv of Taek-li-ji, opinion, in consideration of the place of good settlement, has the author the conclusion ; nowhere, but by means of "I Ging" can be found a good one - place of no place. In the text, we find some other questionable points. In means that the content of this book must be to make understandable and we need a solution of the contradiction in context. 1 think it might be intended by the author. In this study I have tried, the intention of the author to find and the context to review, in order to interpretate the text and to resolve its contradiction. And I have earned a hidden opinion of the author, the second intention of the book.
