  • 지리정보는 시간이 흐름에 따라 변하는 정보를 계속 저장 유지 및 관리하여야 하기 때문에 데이터의 양이 계속 증가하고 용어간의 관계도 더욱 복잡해진다. 이러한 지리정보의 특성은 네트웍을 통한 정보의 공유 및 재사용을 위해 필요한 데이터 검색을 어렵게 한다. 지리정보의 관리, 해석, 그리고 검색의 효과를 향상시키기 위하여 지리정보분야의 어휘 정의와 분류 그리고 다른 어휘와의 관계를 포함하는 온톨로지를 활용할 수 있다. 본 논분에서는 지리정보 데이터 중 하천 관련 용어간의 온톨로지를 구축하여 지리정보 데이터의 관계에 의한 구조적인 검객이 가능하도록 하였다.

  • The wind resource potentials of South Korea are estimated as preliminary stage using the national wind map which has been being established by numerical wind simulation and GIS (Geographical Information System) exclusion analysis. The wind resource potentials are classifying into theoretical, geographical, technical and implementation potentials and the calculation results are verified by comparing to other countries' potentials. In GIS exclusion, urban, road, water body, national parks and steep slope area are excluded from onshore geographical potential while water depth and offshore distance from the shoreline are applied as offshore exclusion conditions. To estimate implementation potential, dissemination records of European countries are adopted which is about 1/8 of geographical potential. The implementation potential of South Korea would correspond 12.5GW which is 1.7 times of the national wind energy dissemination target until 2030.

  • In this paper, we propose Media GIS web service architecture using 3D geographical database and GPS-related data resulted from 4S-Van. We introduce a novel interoperable geographical data service concept; so-called, Virtual World Mapping (VWM) that can map 3D graphic world with real-world video. Our proposed method can easily retrieve geographical in-formation and attributes to reconstruct 3D virtual space according to certain frame in video sequences. Our proposed system architecture also has an advantage that can provide geographical information service with video stream without any image processing procedures. In addition to, describing the details of our components, we present a Media GIS web service system by using GeoVideo Server, which performs VWM technique.

  • Oil Field Geographical Information System (OFGIS) manages multiple spatial data, attribute data, and topographic data, which include almost every kind of ground info rmation and underground information. Subsystems managed by OFGIS include petroleum exploration subsystem (PESS), petroleum development and engineering subsystem (PDESS), petrochemical subsystem (PCSS), petroleum storage and transportation subsystem (PSTSS), petroleum sale subsystem (PSSS), etc. A basic OFGIS framework consists of oil field infrastructure coverage (OFIC), oil field specialized information coverage (OFSIC) and oil field synthesis and decision service coverage (OFSDSC). Basic function of OFGIS includes database management, geographic information management, spatial information processing and application.

콜롬비아 커피의 지리적 표시 활용 전략을 통해 본 지리적 표시의 상업적 의의와 김치의 지리적 표시제 개선 방향 (Understanding the commercial significance of geographical indications and the implications for Korean kimchi through the example of Columbian coffee)

  • A geographical indication (GI) is a sign used on products that have a specific geographical origin and possess qualities or a reputation that are due to that origin. This paper explores ways to protect Korean goods as GIs in the U.S. and EU by examining the efforts of the Colombian Coffee Federation (FNC) to protect Colombian coffee. The FNC enhanced the global awareness of Colombian coffee and increased the profits of Colombian coffee producers by registering Colombian coffee as a certification mark in the U.S. and as a GI under the EU's quality schemes. The Korean government protects kimchi under its own GI system. For kimchi products to earn the label "Korean kimchi," the three main ingredients must be produced in Korea. This has been a challenge for kimchi producers, who often rely on imported ingredients. Korea could learn from FNC's strategies to improve the current GI system for kimchi.
