  • Geography Information System is divided to many details fields such as Urban Information System, Land Information System, Military Information System etc. These detailed fields are connected each other and make National Geography Information System. Now Geography Information System is being used in many fields with Urban Information System. And information of all field is being constructed to network for share each other. Now Land Information System(LIS) is being constructed to two dimensional. But LIS can construct and utilize three dimensional geographic data by connecting Geography Information System and this effect will be greatest. Thus, the study of connecting cadastral map and digital terrain map must be continued. Through the study of connecting digital terrain map, the construction and analysis of three dimensional digital elevation model will be able to construct Land Information System effectively. To this study, the authors constructed integrated geographic data by uniting digital terrain map and cadastral map and constructed three dimensional digital elevation model. By connecting cadastral information database, the authors developed three dimensional Integrated Land Information System.

  • In order to establish and promote geographic information activities in controled environment maximizing interoperability and the degree of reusability of geographic information resources scattered in distributed platforms, standardization is recognized as one of the basic solutions essentially being performed at the community level, where intends to align with international standards. This paper describes some technical aspects of standardization needed to build a systematic mechanism of national geographic information standards development, giving approach to conceptual analysis especially directed by ISO(International Organization for Standardization). Following some enumerated benefits for profile based national standard architecture and the brief review from canadian approach we suggest herein a overview of national and community level standardization framework, which identify its primary elements consisting of common basis for standard development mechanism based on profiles.

  • For GIS to land and sea in Korea, GIS on land was almost completed with big cities by NGIS(National Geographic Information System) business. However, MGIS(Marine Geographic Information System) being constructed by the National Oceanographic Research Institute is still constructing geography information and definition of attribute information and real condition. We are being studied on research to get maximized the ripple effect linking GPS and Navigation techniques on GIS. GPS in accuracy is divided into navigation and precise surveying equipment. Now, GPS technology has been developed very much and low price GPS equipments are introducing. But expense on GPS equipment is high yet. Therefore, GPS equipment for navigation is used on cheap GPS equipment in a car or ship. In this paper, the author used algorithm to convert ellipsoid coordinate between WGS84 and Bessel ellipsoid and to analyze map projection between BESSEL ellipsoid and UTM plane coordinate system. And the author developed ship navigation system with cheap GPS equipment using algorithm of ellipsoid conversion and map projection. The author proposed the necessity on constructing MGIS to manage many ships.

  • Coastal cities need disaster planning that accounts for the complex causes of environmental disasters such as high tides or tsunamis generated by typhoons, and of river or lowland flooding caused by heavy rains, etc. The elements of the disaster map were initially defined using a Geographic Information System (GIS) to allow for efficient information management. Complex disaster information elements were thus established in this study to create a disaster map of coastal cities. The range of information required for coastal cities includes the type of disaster, evacuation methods, available sheltering facilities, and learning content. These informational elements are intended to build on spatial information based on data available from the Ministry of Public Safety and Security as well as local governments.

  • Now, there are some problems to manage underground facilities in domestic. Specially, in the case of KEPCO(Korea Electric Power Corporation), it is so difficult to manage electronic line more stably and detailedly because the geographic information and attribute information being built is not easy to be updated in the field. KEPCO officials who are accompanying management and supervision in earthwork do not have sufficient knowledge and information about GIS but they grasp the information of geography and property which coincide with the field. Therefore they have to refer their business analysis contents sufficiently for more efficient lines management in the KEPCO, but it is problem that the existing information of electronic lines management system is not. In this study, we constructed power transmission and power distribution underground facility management system for the user to manage and maintain underground facilities more easily and safely using the information of geography and property about power transmission and power distribution underground facility which have been built by KEPCO.

  • GIS (geographic information system) is a relatively new tool in the coastal and ocean area management toolbox, but its uses and functionality are quickly being recognized. GIS can help identity potential threats to coastal and ocean resources and evaluate alternative land-use and management practices. The application of GIS to coastal and ocean issues continues to grow as the general use of GIS matures. GIS software and technicians with the skills to apply GIS are now commonplace at federal, state and local government agencies as well as many NGOs and the private sector. However, these applications were focused on their special purposes. Therefore, we describe the management strategy of marine GIS and its components. The results of this study can be used as the fundamental guideline for the coastal and ocean management and sustainable development.

  • This study aimed to find the association between geographic proximity and program participation at a Healthy Family Support Center (HFSC). Drawing demographic and geographic information from the participant list at a local HFSC in Seoul for the period 2009 to 2011, this study calculated the geographic distance from the individual residence to the center for 2,343 participants. We found that single time participants had a longer distance from their residence to the center than multiple time participants. When we compared the proximity by program areas, we found that the geographic distance to the center was shorter among education program participants than among non participants. However, there was no difference in the other areas of programs. In terms of the target group, the distance was shorter among adult program participants. Finally, the average distance among participants in multiple session programs was shorter. The results of this study indicated that the relationship between geographic proximity and program participation depended on program areas, target groups, and the number of sessions.

  • We live in an age of information and an era of rising environmental awareness. As a result, efficient and judicious use of environmental information has become a prerequisite to planning and management of environmental affairs in contemporary societies. So, we have embarked on a study of Environmental Information System(EIS). In the first article, we discussed the status analysis of EIS in Korea, USA, and Japan. This study as the second project has three major components. First, it classifies items and sources of 22 EIA factors. Second, it explains building of environmental information comprising geographic and attribute data of 17 factors. Finally, the study presents applications of EIS as an alternative assessment of suitability analysis. Based on these analysis, the study makes some recommendations and conclusions.
