  • This study investigated and analyzed the topographic landscape resources of Mureung Valley in Donghae-si from the viewpoint of geotourism in order to suggest the tourism contents and tour course. A total of 29 topographic landscapes were observed; these are broadly divided into 4 features including weathering landform, mountainous landform, fluvial landform, and structural landform. Major topographies are fluvial landform (13) and weathering landform (12). At least 19 topographies (14 sites, 19 topographic landscapes) are currently used as tourism resources, with 10 topographies having potential to be developed as new tourism resources. The 10 topographic landscapes are as follows: (1) Jamryong Bawi (Hidden Dragon Rock), (2) Janggipan Bawi (Korean Chessboard Rock), (3) Nurungji Bawi (Parched Rice Rock), (4) Damjang Bawi (Fence Rock), (5) Gyedan Bawi (Stairs Rock), (6) Heundeul Bawi (Rocking Rock), (7) Jeopsi Bawi (Dish Rock), (8) Dol Umul (Stone Well), (9) Jogak Bawi (Carved Rock), and (10) Dubu Bawi (Topu Rock). The topographic tour course can be divided into 3 routes considering accessibility and time. Route 1 is a basic one that anyone can easily use; Route 2 and 3 can be used by visitors who have more time to spare or who are more active.

  • In this study, a total of 80 rock formations in the romantic road(Nangmangado) were investigated and analyzed and the results are as follows. The area in where the rock formations landscape is seen the most is Yangyang(43 formations), and the formations are most densely concentrated in Jukdo beach when seen from the site group. The most observed landform is weathering landform(61%) and the rest is comprised of coastal landform(24%) and structural landform(15%). For weathering landform, Tafoni takes up the largest portion (33%) and is followed by Corestone(27%), Tor(22%), Gnamma(10%), Groove(4%) and Exfoliation(4%). Considering academic value, rarity and accessibility overall, the 35 landforms are expected to have high utility value as tourism resources and topography filed course. And out of these 35 landforms, 11 are concentrated in Dongsan beach in Yangyang. Therefore, it seems worthy to consider developing Dongsan beach under the name of "Dongsan Coast Rock Park(Tentative Name)" to be actively utilized as tourism resources. The landforms which are evaluated as highly valuable for geomorphology filed course are a total of 16 areas including Fan rock and Op rock formations. In these areas, typical weathering landforms are concentrated in one spot and two or three other types of landform can also be additionally observed, allowing the place to be highly efficient for field education.

  • To consider geomorphological and geological characteristics to Gatbawi(the 500th natural monument), it was investigated with the aspect of scale, form, mineralogy, chemistry and weathered state. Showing typically erosional features, micro-terrains as sea cliffs, sea notches, marine plateaus and tafoni developed well on coastal areas near the monument. Sea cliffs are vertical and form sea notches in their bases. Coastal terraces are 3.5m in width and 20m in trace. Tafoni are honey combed. The monument is mainly composed of quartz, plagioclase, microcline, biotite, sericite in mineral and corresponded to crystalline tuff dominated in quartz and plagioclase. It has 23.60~28.27 wt.% of $Al_2O_3$, 3.27~5.80 wt.% of $Na_2O$, and 0.11~0.20 wt.% of Cl in chemical contents, leveling higher than those of earth crust standards. It is considerably weathered on the basis of CAI(77.42~83.93%). The monument is very useful for natural perspective tourism and education. Therefore, it is necessary that several ideas as guide plates, observing telescope, explaining guider, education programs connected with related services, touring goods, picture for books on utilization on the monument must establish.

  • In this study, we analyze seabottom conditions and characteristics integrated with topographic data, seafloor mosaic, underwater images and orthophoto(drone) of soft-hard bottom area around the Sib-Ri rock in the northern shore of the East Sea(Gyeongpo Beach, Gangneung). We obtained field survey data around the Sib-Ri rock(about 600 m × 600 m). The Sib-Ri rock is formed by two exposed rocks and surrounding reef. The artificial reef zone made by about 200 ~ 300 structures is shown the western area of the Sib-Ri rock. The underwater rock region is extended from the southwestern area of the exposed the Sib-Ri rock with 9 ~ 11 m depth range. The most broad rocky seabottom area is located in the southwestren area of the Sib-Ri rock with 10 ~ 13 m depth range. The study area were classified into 4 types of seabottom environment based on the analysis of bathymetric data, seafloor mosaics, composition of sediments and images(underwater and drone). The underwater rock zones(Type I) are the most distributed area around the Sib-Ri Rock(about 600 m × 600 m). The soft seabottom area made by sediments layer showed 2 types(Type II: gS(gravelly Sand), Type III: S(Sand)) in the areas between underwater rock zones and western part of the Sib-Ri rock(toward Gyeongpo Beach). The artificial reef zone with a lot of structures is located in the western part of the Sib-Ri rock. Marine algae(about 6 species), Phylum porifera(about 2 species), Phylum echinodermata(about 3 species), Phylum mollusca(about 3 species) and Phylum chordata(about 2 species) are dominant faunal group of underwater image analysis area(about 10 m × 10 m) in the northwestern part of the Sib-Ri rock. The habitat of Phylym mollusca(Lottia dorsuosa, Septifer virgatus) and Phylum arthropoda(Pollicipes mitella, Chthamalus challengeri hoek) appears in the intertidal zone of the Sib-Ri rock. And it is possible to estimate the range and distribution of the habitat based on the integrated study of orthphoto(drone) and bathymetry data. The integrated visualization and mapping techniques using seafloor mosaic images, sediments analysis, underwater images, orthophoto(drone) and topographic data can provide and contribute to figure out the seabottom conditions and characteristics in the shore of the East Sea.

  • Rock platforms and TTP (breakwater) are dangerous environments commonly subject to tidal and high wave energy on the open coast. This paper is a study on risk assessment to provide risk information, which is a representative method for preventing coastal safety accidents. Risk assessment based on geo-morphological information was conducted for the Halmi-Halabi rock platform in Anmyeon-eup, Taean-gun, Chungcheongnam-do. As a result of the risk assessment in 16 directions, the risk was evaluated high in the NE, ENE, S, SSW, and W directions, where there are many sections with slopes exceeding ±20°, and the NW direction was the lowest. Geo-morphology on rock platform is central to understanding what makes one stretch of complex coastline more hazardous than another, and it can be used to create site-specific morphological risk item. In particular, it will be assisting coastal managers in an effort to reduce the number of injuries and drowning incidents by providing hazard information to assess the relative risk.

  • Even though various geological attractions are distributed domestically, the geological attractions are rarely utilized as field course site. The purpose of this study is to make Seonangbawi area as the field course site after geological investigations are carried out in detail. Seonangbawi is located about 1km southeast from Songjiho beach in Gangwon-do. Seonangbawi area is simply composed of Cretaceous Seokcho granite with the overlay of Quaternary alluvium. Geological field course in the Seonangbawi area will be useful to the student and citizen for developing the knowledge of geological phenomena, such as the formation of granite and minerals, and weathering process. In addition, the student and citizen can develop the knowledge of the geological structures, such as joint (N50E/80NW, N40W/84SW), fault (N42W/83SW), foliation (N32E/54SE), and dyke (N35E/40SE, N26W/63SW), and geographical features, such as tor, taforni, groove, and gnamma in the field. Accordingly, the Seonangbawi area is the best place to learn various geological and geographical phenomena and to discuss the origin of Seonangbawi with limited space.

  • This paper aims to excavate and make storytelling of cultural landforms around Shincheon, Geumho river in Daegu and then to build the strategy for making its application. The main results are as follows. 1) There are main cultural landforms such as Yongdubawi(龍頭岩, river cliff), river cliff, rock shelter(岩蔭), sheeting joint landform, river cave, tor, etc. around Shincheon. 2) there are main cultural landforms such as riverine wetland, ferry, point bar, river cliff, Hwadam(畵潭, pool), Donghwacheon(stream), Mutae(無怠), Chimsan(hill), Yeonamsan(hill), Sanghwadae(river cliff), etc. around Geumho river. 3) It is necessary to excavate and restore cultural landforms around Shincheon and Geumho river for protection, Also the valuable cultural landforms should be designated as cultural assets in order to prevent damage. 4) Considering from application of cultural landforms around Shincheon, natural observation site need to be designed for experiencing culture, history and ecological environment. However, in viewpoint of application of cultural landforms around Geumho river, it is much better to plan a few of Geumho river cultural landform trails for self-guided tour.

  • 본 논문은 지형중심 게임에서 깊이레벨에 기반한 텍스처 분석 테이블(TAT)을 이용하여 높이에 따라 정의된 지형 객체들을 효율적으로 생성 시킬 수 있는 알고리즘을 제안한다. 기존의 방법에서는 맵에디터 상에서 지형의 텍스처와 지형의 사실적 표현을 위해 나무나 바위 등의 지형 객체를 수작업으로 편집하였는데 제안한 알고리즘을 적용하면 깊이 단계별 최소의 지형 텍스처만을 사용하여 매우 다양한 종류의 지형 텍스처를 생성해 낼 수 있으며, TAT로부터 깊이 정보값을 활용하여 자연-객체들(Natural Object)을 자동으로 생성시킬 수 있다. 이로써 게임 지형을 제작하는데 불필요한 작업량을 줄일 수 있으며, 그만큼 인공-객체들(Artificial Obejct)을 생성하는데 많은 시간을 투입할 수 있다.
