  • Much research on semantic geographic information systems that incorporating the Semantic Web and geographic information has been actively studied. However, the existing geographic information systems have a system dependency problem that users can input and retrieve non-spatial information only in a specific system. It also causes difficulty in providing rich services. Therefore, this paper proposes an implementation model for population of Geo-ontology from non-structured Web resources. The proposed model can populate instances for Web ontology independently of systems, and thus it enables a richer Web service development. Finally, this paper shows the prototype that populates instances including a Geo-ontology building example for a University selected as an application domain.

  • 현재 웹은 단순히 정보를 수집하여 제공하던 웹 1.0을 지나 정보의 사용자가 곧 생산자가 되어 개방된 웹 환경을 기반으로 사용자 스스로 콘텐츠를 제작, 재창조, 공유하는 인터넷 서비스 모델인 웹 2.0으로 발전하였다. 이러한 웹의 발전 과정에서 시맨틱 웹이 등장하게 되었고 시맨틱 웹이 지리 정보와 접목되어 시맨틱 지리 정보 시스템이 등장하게 되었다. 기존 지리 정보 시스템에서는 사용자들이 국한된 정보만을 제공받아 왔지만 웹이 발전하고 수많은 콘텐츠가 생성되면서 웹의 데이터를 지리 정보 시스템과 연결시켜서 사용자에게 풍부한 정보를 제공 할 수 있는 시스템이 연구, 개발되고 있다. 하지만 기존 연구들은 사용자가 시스템에 접속하여 비공간 정보를 입력해야 하는 특정 시스템에 종속적이라는 단점을 가지고 있어 시맨틱 웹에서 지향하는 풍부한 서비스 제공에 어려움을 격고 있다. 따라서 이 논문에서는 웹 자원을 정의된 지리정보 온톨로지(Geo-Ontology)의 인스턴스로 추가하여 지리 정보 시스템의 비공간 정보를 확장함으로써 특정 시스템에 종속적이지 않고 사용자에게 보다 풍부한 서비스를 제공하기 위한 모델을 제안하고 프로토타입을 구현한다.

  • As the digitization of maps in Korea has been completed in 1998, local governments begin to apply digital maps for their administrative convenience. In applying GIS to local administration, there are some important aspects to be considered such as technical aspect, organizational aspect and data managerial aspect. Using surveys to local governments, the study examines the implementation factors such as leadership, GIS organizational settings, human and financial resources, and education programs which are related to the applications of GIS to local governments in Korea. As a conclusion, the study proposes that organizational and human factors be combined harmoniously with technical factors from the beginning stage of GIS installation for the successful implementation of GIS applications to local governments.

  • 최근 컴퓨터 기술이 발전하면서 GIS(Geographic Information System)에 근거한 다양한 형태의 GIS 응용 시스템이 연구 및 개발되고 있으며, 또한 인터넷의 발전으로 사용자 측면의 기술도 발전되어 가고 있다. 이에 따라 다양한 사용자의 요구에 대해 마른 결과를 제공할 수 있는 지리 정보 시스템7: 필요하게 되었다. 그러나, 일반적인 지리 정보시스템은 데이타의 처리와 전송에 상당한 시스템 자원을 소모하는 단점이 있어 이를 개선할 필요성이 있다. 각각의 컴퓨터를 직접 연결하는 P2P 기술은 자원의 공유를 통한 저장 공간의 절약, 데이타 전송의 효율성, 클라이언트의 기능 활용 등의 장점을 가지고 있다. 이러한 P2P를 이용하면 이전의 방법에서 문제시되었던 과부하, 접속 지연, 전송비용 과다 등의 문제들을 해결할 수 있다. 따라서, 본 논문에서는 기존의 클라이언트/서버 형태 지리 정보 시스템의 문제점을 파악하고, 이를 극복하기 위한 방안으로 P2P를 살펴보았다. 또한 이를 토대로 다양한 미러링 클라이언트를 두어 서버의 과부하나 전송 비용 과다를 줄이고, 클라이언트의 활용도를 높여 기존의 클라이언트/서버 형태의 지리정보 시스템의 문제점을 보완한 P2P 기반의 공간 데이타 미러링 시스템을 설계 및 구현하였다.

  • In this study, for the application of land resource evaluation using GIS map overlay method, I have considered about the process that can draw out right results from the problems involving multiple hierarchical indicators and weights. The assumption of this research is that there are two processes in the application of analytic hierarchy process(AHP) and the different results will appear. The two processes are as follows; (1) calculate directly the comprehensive weights to the indicators and overlay the layers(Method I) and (2) repeat the process of map overlay and standardization(Method II). The two precesses are applied on the study site based on the envirosystem in Bong-Hwa, and then some differences were found in the results and it was suggested that the Method II is more reasonable.

  • This study was conducted to analyze community structure and species composition of Abies koreana forest. Field survey was carried out from June, 2019 to 2020, September. 121 plots (20×20 m) were set up, 5 herb layer plots (3×3 m) were constructed for each plot, and there, Diameter at Breast Height(DBH), height, environmental factor were measured. It was analyzed that water stress did not have a significant effect on the factors affecting the growth of A. koreana in Mt. Halla-san, and in the case of Mt. Deokyu-san, the more forest stands located at the ridge, the higher the tree density. It was found that the factors affecting the distribution of Abies koreana were not consistent according to the environment of study site.

  • Human has noticed a beautiful natural scenery and appreciated it as a scenic site by giving meaning to it and evaluating it. How the beautiful natural scenery was appreciated as a scenic site depends on natural features, social and cultural environments, and the current of the times. Mt. Jiri is the highest mountain in inland South Korea and keeps ancestors' history and culture intact. Joseon Dynasty literary men frequently mentioned Mt. Jiri as a tourist attraction where they could pursue and share their studies against its beautiful natural scenery. The countless literary men visited Mt. Jiri and some of them left their journeys as travelling records. This research aimed at apprehending travel routes of Chunwang Peak of Mt. Jiri based on the contents of travelling records and investigating the scenic site value of scenic resources as the literary men in Joseon Dynasty recognized. The scenic resources of Mt. Jiri were related to the change of the reason or motivation of person who climbed and it should be noted that there was a change of reason or motivation in climbing Mt. Jiri from a following of master's paths to discovery of a new trails. Thus, even if there was a difference in reason or purpose of natural scenic beauty, the concept of scenic sites of the past and the present day should be included into the extended meaning of scenic sites. This research aimed the routes of well-known literary men need to be developed as programs utilizing "the concept of ancient sages' footprints" and the development of these contents shall be used for vitalization and self-support of a regional economy.
