  • GIS is considered as a big industry or business in the field of applied sciences. Recently GIS market in Korea is growing rapidly for LBS, Telematics, Web-geographic information services. This paper attempts to focus on the interrelationship between GIS and geography, and the question of how geography emerged out of intellectual trends within GIS to examine possible contribution of geographers in GIS fields. The application of GIS appears to be largely technical in nature. It is important for the GIS operator and the consumer of GIS products to be aware of the geographical concepts that underpin GIS operations. Also it is seen that many departments of geography in Korea have attempted to actively adopt GIS into their education program, with aim to improve the status. GIS has promoted a shift towards applied geography from academic geography. GIS researchers and educators in geography are concerned not with technology, but with the basic concepts and the issues relating to its use, in comparison with other academic fields. It is the responsibility of geography community to make sure that our students receive a geographical education that includes problem-solving, critical thinking and technical capabilities. It is concluded that promoting GIS technology in geography curriculum is essential for the further expansion of geography within GIS and also for the survival of geography.

  • This study attempts at building a GIS computing environment that incorporates object-relational spatio-temporal database for the time geography model with space-time path, space-time prism and space-time accessibility. The proposed computing environment is composed of ( i ) mobile GIS application for collecting spatio-temporal trajectory data of an individual, ( ii ) spatio-temporal database server that includes time geography model, and (iii) geovisualization client that performs time geographic queries to the spatio-temporal database. The spatio-temporal trajectory data collected by GPS-PDA client is automatically processed and sent to server through data management middleware. The spatio-temporal database implemented by extending a generic DBMS provides spatio-temporal objects, functions, and SQL. The geovisualization client illustrates 3D visual results of the queries about space-time path, space-time prism, and space-time accessibility. This study confirms the possibility of integrating mobile GIS and DBMS for time geography model, and it presents the appropriate database model with spatio-temporal objects and functions that may handle very large data for time geography application.

  • This article reviewed issues in Korean geographical journals: web GIS and National GIS. Web GIS in Korea is now evolving to mobile GIS, which requires portable hardware, wireless Internet, and GPS receiver. The new trend of mobile GIS is using a smart phone. Recently, a variety of studies for the mobile App and mobile Web in Korea has been developed. With explosive information on the Web 2.0, the Korean government has built the Human-Oriented Geographic Information System (HOGIS) in which Ontology was implemented for semantic query on the Web. On the government side, Korean government has produced various nationwide data through 4-phase NGIS project. Current NGIS ($4^{th}$ phase: 2011-2015) moves toward a Korean Green Geospatial Society using geospatial information as a new growth engine for the future.

  • UN은 1990년대를 전세계적인 자연재해 감소를 위한 10년(IDNDR)으로 지정하고 이러한 취지로 제네바에 사무국을 개설했다. 그에 대한 반응으로 국제 과학 연합회는 IGU를 통해 여러 지역에서의 지리적 연구를 지원하고 있다. IGU는 1992년에 개최된 제 27차 IGC에서 자연재해연구 분과를 개설하여 지리학에 있어서 새로운 기술을 개발하는데 강조를 두는 다양한 자연재해 프로젝트에 지리학자들을 포함시키려는 노력을 시작했다. 지리학자들은 IDNDR에 중요한 공헌을 하고 있는데, 특히 재해 관리를 위한 GIS의 영역과 지도화와 재해 평가를 위한 원격탐사, 재해 반응에 대한 GPS의 이용 등이 이에 포함된다. 지리학자들은 지도화와 재해를 경감시키려는 노력에 중요한 역할을 하고 있으며, 이미 재해를 입은 지역에 대해 복구 계획을 세우고 있다. CONAHA는 2000년에 서울에서 개최되는 제 29차 IGU에서 UN에 의해 시작된 안건을 지지하게 됨으로 그 역할을 마무리하게 될 것이다. 영구적인 공헌 중에는 1998년에 산악 재해에 관한 발간을 시작으로 자연재해에 관한 책 시리즈와 UNESCO에 의해 발간된 Life Systems 백과사전 내용 중 자연재해에 대한 부분이 포함된다는 것이다

  • Geography has played a role of serving as a bridge between the natural and social sciences for long time and can be an interdisciplinary framework. In this research, the effectiveness of an interdisciplinary approach centering on a geographical perspective in environmental education is presented. On this basis, a syllabus for seven 90-minute classes for the 8th grade is established under the topic of "Studying the Environment of Eighteenmile Creek." This interdisciplinary framework will be strengthened and vitalized through GIS, which plays an important role to make the geographic and environmental education more student-centered, active, and relevant to the world where we now live.

  • Recently spatial modeling that combined GIS and Cellular Automata(CA) which are based on dynamic process modeling has been discussed and investigated. However, CA-based spatial modeling in previous research only provides the general modeling framework and environment, but lacks of providing simulation or transition rules for modeling. This study aims to propose a methodology for extracting spatial relation rules using GIS and Knowledge Discovery in Database(KDD) methods. This new methodology has great potentials to improve CA-based spatial modeling and is expected to be applied into several examples including urban growth simulation modeling.

  • 본 연구에서 구축한 PC-based GIS는 소규모 예산의 교육용 및 연구용 시스템이다. OSU MAP은 PC XT에서도 운용되기 때문에 최저 157만원선(CPU 100만원+디지타이저 50만원+소프트웨어 7만원)으로 장비할 수 있다. 그러나, AT386기종에 값싼 디지타이저와 선형배열스캔너를 부착한 하드웨어 시스템과 래스터/벡터 자료구조의 소프트웨어 시스템을 장비하는 데에는 약 2000만원 선 (CPU 500만원+디지타이저 50만원+스캔너 300만원+소프트웨어 1000만원)이 소요된다. 6-7년 전에 이와 유사한 처리능력의 32비트 기기를 장비하려면 최소한 3억원의 예산이 소요되었던 것을 고려하면 대단한 가격하락이다. 이제, 우리나라에서도 약간의 지혜와 성실을 바탕으로 교육용 및 연구목적의 GIS를 향유할 수 있게 되었다.

  • We examined research trends in geomorphology and hydrogeography in America based on papers presented at the annual meetings of the Association of American Geographers(AAG) and papers published in two AAG journals between 2002 and 2004. Among the 437 papers in geomorphology, $40\%$ of the papers concerned fluvial geomorphology, followed by environmental geomorphology and glacial and periglacial geomorphology concern. Among the 452 papers in hydrogeography, about $20\%$ of the papers focused on water, law and institutional aspects, followed by hydrogeomorphology and hydrologic modeling. Twenty one papers examining geomorphology and hydeogeography were published in two AAG journals, and fluvial geomorpholoy was the dominant theme. GIS was used for $29\%$ papers in geomorphology and $35\%$ of papers in hydrogeography($35\%$), suggesting that other methods, including geostatistics, field survey, and qualitative methods, are employed as well. This methodological diversification seems to be associated with solving such complex environmental problems as integrated watershed management and implies that geomorphologists and hydrogeographers are expanding their traditional territories and are making close connections with human-environment geographers and human geographers. Geomorphologists and hydrogeographers are likely to continue examining the causes of and solving environmental problems that humans are currently facing and might face in the future.

  • The purpose of this study is to analyze spatial patterns of traffic accidents and to investigate spatial relations among neighboring spatial objects by applying GIS and spatial data mining methods. This study investigated traffic accident data in Kangnam-gu, Seoul, as a case study. As a result, four clusters were emerged based on individual attributes of traffic accidents. Each cluster showed distinctive properties. In spatial associations between individual attributes of traffic accidents and neighboring spatial objects, there were many rules according to concept hierarchy and definition of spatial relations. Although all rules were not be interesting and significant, they could be a clue to investigate more.
