  • The purpose of this study is to present the role of NGIS(National Geographic Information System) and the development strategy for Business GIS in the ubiquitous society. We analyze the level of GIS technology with the ICT(Information Communication Technology) as well as GIS application trends especially in location-based circumstances. Also, we advocate not only making GIS contents to meet the international standards such as GML(Geography Markup Language) and TPEG(Transport Protocol Experts Group) but applying GIS as a killer application to oncoming diverse ICT areas including LBS(Location -Based Service), Telematics, ITS(Intelligent Transport System), gCRM(geographic Customer Relationship Management), DMB(Digital Multimedia Broadcasting), u(ubiquitous)-City and u-Town. Finally, we build a conceptual Business GIS model based on NGIS for QoS, standardization, R&D, education, and security.

  • 최근 정보기술의 동향을 살펴보면 공통적인 키워드를 발견할 수 있는데, 그것은 바로 모바일(Mobile)이다. 이에 GIS 분야에서도 무선환경에서의 GIS 활용을 위한 기술이 확산되고 있으며, 대표적인 기술로 LBS(Location Based Service)와 모바일 GIS(Mobile GIS)가 있다. 이러한 배경하에 선진국가에서는 고도화된 전자정부 구현을 위해 무선 GIS 기술적용이 추진되고 있으며, 국내에서도 모바일 전자정부 추진계획이 수립되었다. 이에 본 논문에서는 공공분야에서 효율적인 무선 GIS 기술도입을 위해 공공분야의 무선 GIS라는 개념을 제시하고, 무선 GIS 서비스 구현의 기반이 되는 서비스 유형을 제시하였다. 공공분야의 무선 GIS 서비스 유형은 LBS와 모바일 GIS를 기반으로 적용 가능한 업무유형과 무선 GIS 특성에 따른 서비스 구조로 구분하여 고찰하였으며, 두 내용을 종합하여 공공분야의 무선 GIS 서비스유형을 제시하였다. 제시된 무선 GTS 서비스 유형은 향후 모바일 전자정부 및 공공분야에서의 모바일 관련 GIS 서비스 구현시 참조할 수 있을 것이라 예상된다.

  • 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.

  • Recently , as GIS technology is rapidly improved and stabilized, there are some needs to reuse pre-developed and powerful GIS technology. GIS standardization based on components and open interfaces becomes a way to solve those reusability of previous GIS technology. This GIS standardization currently focuses on building the GIS Data Infrastructure that is being deployed globally. Especially, OpenGIS consortium which is mainly made up of international GIS leading vendors is announcing some GIS abstract specifications and implementation specifications. This study focuses on how could we design and implement the OLE/COM-based data provider component based on various DBMS or file systems, how could these data provider components be used for enterprise UIS(Urban Information Systems) and how could various formatted GIS data be shared in one system. Also some problems practically caused by an implementation process of data provider component are listed up and some solutions are given. Furthermore, design and analysis of UML(Unified Modeling Language) was reformed through the data provider component development task and this UML methodology is able to indicate a standardized model for newly developed data provider component.

  • According to the development of Internet system recently, we focused in GIS data distribution and applications via internet rather than GIS data construction. Therefore in this paper, we present the necessity of security policy on GTS data. So we analyze the actual condition of GIS data through expert poll. We classify all of data used in GIS with the three security level : high level, middle level, low level. Finally we propose the proper security method on GIS data transfer and on GIS database access in accordance with progree of PKI project.

  • This paper reviews the topic of GIS, the academic setting of GIS, GIS model curricula and the possibility GIS education in Korea. The topics which might be included in a science of geographic information consist of data collection and measurement, data capture, spatial statistics, data modeling and theories of spatial data, data structures, algorithms and processes, display, analytical tools, institutional, managerial and ethical issues. The problems in teaching a course on GIS in higher education are reviewed. Because of their technological, integrative, and rapidly changing nature, GIS pose major challenges to their education system which it is ill equipped to meet. In higher education a number of initiatives have been taken to provide education about and training with, GIS. The possible GIS curricula are suggested. These curricula are divided into 3 major sections, relating GIS context, technical issues and application issues. The prospects of GIS appears lo depend largely upon the future cooperation of academia, government, and industry

  • Although GIS technology has been developed rapidly, the education system for GIS technology and its utilization has not been well facilitated in our society. Consequently, the economic value in GIS application system is not estimated properly in the public sector. On the other hand, industries currently suffer lack of technocrats or researchers to develop GIS. In addition, the demand for GIS education on its concept and know-how has increased drastically as GIS analytic technology has come to be applied to more varified fields. Under these circumstances, this study researched and analyzed the current state of GIS education in the public, private and academic sectors in Korea. Furthermore, it recommended improving the educational environment for GIS experts training based on the results of the questionnaire used in the survey. Most of all, the national investment should be conducted systematically in order to improve quality of education in the public, private and academic sectors.

  • The main questions of this study are how to reuse GIS applications and what to do for interoperability of the applications in local governments. To answer the questions, related technologies and standards of GIS are investigated. International standard organizations, such as ISO/TC211 and OGC(OpenGIS Consortium), are working on GIS interoperability standards based on component technology and distributed computing environments. In this study, a standard model for interoperability of GIS applications in local governments is proposed based on the international standards. Standardization process of GIS interfaces in local governments is as followed: 1) modeling of GIS business and 2) establishment of GIS service architectures 3) defining GIS standard interfaces 4) GIS component. In conclusion, by developing interoperable GIS applications based on component technology the reusability in local governments can be realized.

  • The considerable budgets for the 2nd-phase NGIS projects are allocated to the projects for developments of the GIS applications. Especially, the 78 local governments are major users of GIS application systems. In spite of GIS necessity in local government, whether a GIS is 'good' or bad, depends on its implementation and operation. How to implement GIS in effective wav and how to measure GIS effect for justifying GIS funding can be major concerns. Because it takes minimum 3-4 years to equal the costs and benefits of GIS, the long-terms implementation strategies for GIS project in local government are required. In order to establish a proper implementation model for the GIS application projects and to promote activities in the projects, this study considers several problems in accordance with the phases of GIS evolution and solutions of these problems. Based an the GIS auditing and consulting experience in local governments, this study constructs a GIS implementation and maintenance model in long and comprehensive perspective. This model can be a key to affective and realistic implementation for the future GIS projects.

  • This paper tried to derive a GIS curriculum in geography and the estimation of the number of faculty members to teach GIS. To do this, geography departments of universities in Korea and the United States were compared based on the number of faculty members and the main structure of a GIS curriculum. Five universities of NCGIA and UCGIS in the United States and 27 universities in Korea were selected, and their GIS programs were analyzed on GIS curricula, the size of faculty, and program management. The US geography programs typically provide both GIS majors and GIS certificate programs, but Korean geography programs do not. At least, seven GIS courses(21 credits) are required for fulfillment of major degrees in the U.S., but only two courses(6 credits) are required in Korean geography programs. As far as the size of GIS faculty, it averages less than 25% of entire geography faculty in Korean universities, while it takes up about 31% in the U.S.. In this paper, the establishment of 19 GIS courses was suggested as a GIS curriculum for partial fulfillment of a geography major, and two GIS faculty members were recommended to maintain a stable GIS program of geography departments. The enhancement of GIS curricula and faculty size can provide geography graduates with more opportunities for employment and better react to diverse GIS-related public demands, which are important for the successful future of geography programs.
