  • 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.

  • GIS (Geographic Information Systems) technology is a necessary function to support location based on service by using GPS in the mobile environment. These mobile systems have basic functional limitations such as a low rate of processing, limited memory capacity, and small screen size. Because of these limitations, most of the mobile systems require development of a reduced digital map to overcome problems with large-volume spatial data. In this paper, we suggest using the reduced digital map format in order to use location based on service in a PDA environment. The processing of the proposed data format consists of map generation, redefinition of layers, creating polygons, and format conversion. The proposed data format reduces the data size by about 98% comparing with DXF format based on the digital map of Busan.

  • GIS를 이용한 공간정보의 교육은 이제 선택이 아니라 모든 산업분야에서 폭넓게 채택되고 있는 필수적인 분야이다. 그에 비해 GIS 콘텐츠는 GIS를 하나의 도구를 통해 공부하고자 하는 학생들에 있어 매우 생소한 분야이며, 그 정확한 의미와 학문의 범주를 파악하기가 어렵기 때문에 인터넷을 통해 공간 정보 콘텐츠를 쉽게 접근 하고자하는 의도에서 현재 사용하는 커리큐럼의 분석을 통해 GIS 콘텐츠 기반에서의 공간정보의 적용방안을 제시한 것이다. 그리고 참여자의 관심과 확인을 위해 제천지역의 GIS콘텐츠 사례를 추가적으로 보완하면 더욱 유익한 공간정보교육 사이트로 발전할 수 있을 것으로 기대된다.

  • GIS can be used on almost entire fields of the world, such as the national land management, environmental management, disaster management, enterprise activities, and general lives. GIS is called as an infrastructure of the knowledge information on the cultural society. For insuring the national power on the periods of the unlimited competition, it is very important to establish the national information infrastructure. Purpose of the NGIS project I is to development on living benefits of peoplethrough an efficiency of policy and rationalism of planning. In order to achievement of this purpose, the NGIS project I has been established using the national geographic information base planning. The NGIS project I consists of the master management part, the geographic information part, the technique development part, the standardization part, and the land Information part. These five GIS project parts are operated by four governmental ministers and related institutions, such as minister of transportation and construction, minister of science and technology, minister of information and communication, minister of administrative and home affaires. The NGIS I project is to establishment of the nation spatial information systems, such as various nationwide digital maps, GIS technique development, GIS education, GIS standardization, and GIS researches.

  • To overcome the mismatch of heat demand and heat supply is important as considering point on heat utilizing aspects in Urban area. At this point, It need to know the plan of heat networks on the heat balance aspects. The purpose of this study is to know the method of heat evaluation on heat network around costal area. It is need to building uses to calculate the amounts of heat demand. 25 different types of building uses were supplied, but it was reclassified 10 types and calculated the amounts of heat demand in the costal area. The results was described on the area with GIS mapping.

  • In spite of the usefulness of migration statistics in spatially understanding social processes and identifying social effects of spatial processes, services and analyses of the statistics have been restricted due to the complexity of their data structure. In addition, flow mapping functionality which is a useful method to explore and visualize the migration statistics has yet to be fully represented in modern GIS applications. Given this, the purpose of this research is to demonstrate the possibility of flow mapping and the exploratory spatial analysis of the migration statistics in a Web GIS environment. For this, the characteristics of the statistics were examined from database, GIS, and cartographic perspectives. Then, O-D structure of the migration statistics was converted to spatial data appropriate to f low mapping based on the characteristics. The interface of Web GIS is specialized the migration statistics and provides exploratory visualization by allowing dynamic interactions such as spatial focusing and attribute filtering.

  • In this paper, acoustic signals in GIS were analyzed by using wavelet transform and FFT to distinguish sound source caused by collision of particles and partial discharges. As a result, the analysis using wavelet transform was more accurate than that using FFT. Therefore, wavelet transform was useful technique to analyze the acoustic signals in GIS.

  • This study aims to analyze the characteristics of GIS-related test items of high school Korean Geography in the 7th National Education Curriculum, and to discuss some issues and challenges. First, we developed a framework for analyzing test items based on the literature review and the content analysis on the textbooks, which categorizes test items in terms of content elements and activity elements. Then, we examined test items of nation-wide tests including CSAT(College Scholastic Ability Test) carried out 2004-2012 and analyzed the percentage of correct answers as well. According to the results, there was a significant predominance of particular test item categories, and the percentage of correct answers of GIS-related items was slightly higher than whole average but it depended on the test item categories. Finally, we discussed the implications of this analysis to the tests as well as the teaching-learning process in the classroom, and suggested improvement directions such as integration of GIS with other contents, reinforcement of the inquiry-based test items, maintaining moderate difficulty.

  • Rapidly evolving field of GIS and the social demand for university education to address the gap in the training of human resources, and future-oriented, engineering accreditation system based on the introduction of measures in the field of GIS is the need. In this thesis, the domestic and international undergraduate curriculum including University of Seoul's was analysed. A GIS curriculum of the domestic and abroad department course was analyzed. The present status of the domestic engineering accreditation and problems were analyzed and a desirable casting plan was shown through the abroad GIS related accreditation case analysis to analyze the validity of the engineering accreditation introduction of the GIS field. A standardized GIS curriculum was shown through the analysis of the core curriculum and the body of knowledge of the GIS field shown at the advanced of foreign countries all together. The industry-academia cooperation forum which made the Surveying and GIS related society the center by a political alternative, the construction of the caucus and the argument to execute this effectively are needed.

  • The main objective of the paper is to develop a GIS-based method for delineating spatial clusters. Major tasks are: (i) to devise a sustainable algorithm with reference to various methods developed in the fields of geographic boundary analysis and cluster detection; (ii) to develop a GIS-based program to implement the algorithm. The main results are as follows. First, it is recognized that the AMOEBA technique utilizing LISA is the best candidate. Second, a modified version of the AMOEBA technique is proposed and implemented in a GIS environment. Third, the validity and usefulness of the modified AMOEBA algorithm is assured by its applications to test and real data sets.
