  • 이 연구는 고등학교에서 GIS 교육의 현재와 발전 방향에 대하여 살펴보았다. 첫째, 최근 개편된 고등학교 교육과정에서는 GIS에 대한 내용과 비중이 늘어났으며, 이에 따라 GIS 교육에 대한 관심과 수요가 커지고 있다. 둘째, GIS 교육을 위한 GIS 교육 프로그램 개발이 시급한 상황이다. 교과 과정 설정에 부합되는 교육 프로그램과 제반 환경이 부족하여 교수-학습 현장에서의 GIS 교육이 활발히 진행되지 못하였다. 이에 본 연구는 기본적인 GIS 교육 프로그램을 제안하였다. 셋째, 향후 학교 교육에서 GIS 교육은 ‘GIS를 활용한 교육’과 ‘GIS에 대한 교육’의 통합이 바람직한 것으로 분석되었다. 정보화가 진행될수록 GIS 교육의 중요성이 높아지게 될 것이다. 현재 GIS 교육을 담당하고 있는 ‘지리’ 과목을 중심으로 이에 대한 체계적 준비와 연구가 필요하다.

  • GIS is the tool widely used for the practical solution of spatial problems in every region regardless of the language and ideology. In this paper research trends and tendencies of GIS in North Korea are reviewed compared with those in South Korea. For this purpose, academic publications on GIS in North Korea are surveyed and classified according to main subjects in GIS. Such classification by main subjects of GIS in North Korea are conducted on the basis of the classification of research trends and tendencies of GIS in South Korea. As a result, researches in North Korea are mainly focused upon such fields as geodetic surveying and measurement, map manufacture, atmospheric phenomena, agriculture and disasters, while there are few studies related to such fields as national GIS policy and circulation, GIS education, internet-based GIS, and traffic, to name but a few. Most parts of applied data are based on low and medium resolution image such as meteorological satellite images, Landsat images, and so on. This reflects the low level of the development of GIS DB infrastructure in North Korea.

  • Due to the rapid advance in web and mobile computing technologies, normal users have become to produce, provide, and share a varied form of spatial data and information. In the domain of spatial information, numerous researches on GIS have been conducted to provide spatial information services based on a geo-sensor network and a data integration and processing technology. However, to provide user-oriented information, a context information model is necessary to associate GIS data with web and sensor data. Context awareness services is designed to provide specific information, minimizing users' interference. For which, the context information model expresses the relationship of various data from sensor networks and mobile applications and provides a user-specific information considering location and area of interest. Thus, this research aims to develops a context information model based air-pollution information system that obtains and analyses air pollution data and reflects the analysis results on an air-pollution policy. Also, this system aims to raise citizens' awareness on air-pollution and to promote citizens' participatory to improve city's air quality.

  • GIS Tools is able to not only store the integrated information between attribute data and spatial data, but also analyze them. Most of GIS Tools support current information of land. However, lawsuit of right of possession as well as statistic of past data for land policy may need historical information. Therefore, in the paper, we designed the spatiotemporal operators what can handle the historical information. and implemented them. The spatiotemporal operators are used in the history management system of Cadastre and Cadastral map based on GIS. The historical information is generated in spatial operation of spatiotemporal operators and then the implemented operators provide a function to store the historical information, and handle them.

  • Land suitability assessment is the procedure that assesses development, agriculture or conservation suitability of land according to such criteria as soil, location and usability. But there are many problems to execute land assessment by law. Problems include inadequate basic data, lack of linkage with the spatial planning system, and inefficiency in operation. The purpose of this study is to improve methods of land suitability assessment as a sustainable land use management tool using case study. In this study, land suitability assessment will be executed through GIS. On the basis of the results of this case study, practical and institutional problems are described, and technical solutions are suggested.

  • MARPOL (Maritime Pollution Treaty) 부속서 (Annex VI) 경우 대기오염 규제 내용이며, 최근 선박 배기가스 배출규제 강화 목적 개정됨에 따라 관련 규정을 충족하기 위한 적극적인 조치가 요구된다. 예를 들어 Sulfur Dioxide (SOx, 황산화물) 경우 2020년 기준 전 세계 해역 내 운항하는 선박은 황 함유량 0.5% 기준의 배출 요구 기준을 충족해야 한다. 배출규제 해역 지정 시 해당 해역 선박 배기가스 배출량 계산 산정 기준 확립이 필요함에 따라 대기환경에 대한 종합적인 분석이 필수적으로 요구된다. 본 연구에서는 황산화물 배출량 산출 방법론으로써 그리드 셀 내 선박 점유시간을 계산한다. 점유시간이 길수록 선박 통항 및 배기가스 배출이 밀집되어 있음을 의미한다. 밀집도 분석에 더불어 선박의 특성이 반영된 시간당 배출량을 적용하여 배출 공간 인벤토리를 구축하였으며 분석 결과를 GIS (Geographical Information System) 환경에서 공간 지도로 시각화하였다. 기존 국내 황산화물 배출규제 해역의 효과 평가에 더불어 외항 범위까지 규제 확대 시나리오확립 후 비교 평가를 통하여 배출량 감소 효과를 정량적으로 확인하였다.

  • Personalization is user oriented dynamic method based on user preferences for easy access to what users want to view or get. It has become more important in mobile domain with rapid growth of wireless Internet and mobile phone market after success of web based market and therefore, it can be applied to service of spatial analysis result. In this paper, spatial analysis using user profile and notification service methods are proposed as one of personalized spatial data service methods for mobile users. A service system for spatial analysis with user profile is designed to prove possibility of spatial analysis based on user preferences and notification service is also designedto show generated output can be sent to user's mobile devices efficiently to make users informed of preferred information. Prototype system is implemented and it is applied to real estate data that has many selectable conditions by users. Information service based on user preferences can be applied to spatial data by using proposed system and it is efficient when cache module is used to shorten response time. Various user models for application domains and performance evaluation methods need to be developed in the future.

  • NGIS project was carried out to accelerate Korea to an information-oriented land. NGIS Project also is to support training projects for GIS specialists as a sub-project. This program has two categories which are long-term courses and short-courses. The long-term courses are for people who want to get a job in SIS(Spatial Information System) field and also for public services personnel who want to acquire the latest SIS technology. Short-term courses are about the latest GIS component technology and utilization spatial data. In this paper, we analyze education programs and training courses relate to SIS. Also we suggest some directions to train specialists for the effective achievement of SIS project. To efficient education for SIS specialist, education programs have courses without repetition and courses are separated by technology type.

  • A large suite of official statistical data sets has been compiled for geographical units under the national directives, and it is the quantitative regional analysis procedures that could add values to them. This paper reports our attempts at prototyping a statistical GIS which is capable of serving over the Web a variety of regional analysis routines as well as value-added statistics and maps. A pilot database of some major statistical data was ingested for the city of Seoul. The baseline subset of regional analysis methods of practical usage was selected and accommodated into the business logic of the target system, which ranges from descriptive statistics, regional structure/inequality measures, spatial ANOVA, spatial (auto) correlation to regression and residual analysis. The leading-edge information technologies including the application server were adopted in the system design and implementation so that the database, analysis modules and analytic mapping components may cooperate seamlessly behind the Web front-end. The prototyped system supports tables, maps, and files of downloadable format for input and output of the analyses. One of the most salient features of out proposed system is that both the database and analysis modules are extensible via the bi-directional interface for end users; The system provides users with operators and parsers for algebraic formulae such that the stored statistical variables may be transformed and combined into the newly-derived set of variables. This functionality eventually leads to on-the-fly fabrication of user-defined regional analysis algorithms. The stored dataset may also be temporarily augmented by user-uploaded dataset; The extension of this form, in essence, results in a virtual database which awaits for users commands as usual. An initial evaluation of the proposed system confirms that the issues involving the usage and dissemination of information can be addressed with success.
