National Geographic Information System(NGIS) should be designed on the assumption that geographic data collected by each national organization should be integrated into geographic database systemically. To achieve this object, NGIS database would be better connected to National Very High-Speed Communication Network. In the process of research, some problems related to Korean NGIS are found. These are standardization, compatibility, extension, issue of making and opening digital map, and issue related to land information. So, it is required that pilot project apply National Geographic Information System in terms of National Very High-Speed computer network project. This project is to contain two main theme building of physical network and special management of network which is related with NGIS.

I would like to describe the contents of National Geographic Information System(NGIS), which is under constructing by stages fer improving the welfare of the people and the competitiveness of the country through the construction of spatial infra and the information-oriented land. The construction of NGIS Is a main enterprise of the 21 century Information-oriented land, also might influence on the real life of the people. Therefore, all the people in the related area such as Land surveying and the industry of Geographic Information System(GIS) should try to make the cinergy-effect and the information-oriented land by endless developing technology and improving the related systems.

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.

This study is to suggests the vision and policy issues on National Geographic Information System in Korea. Firstly, this study is to describe the current situation and problems of national geographic information. ${\ulcorner}$The Second national geographic information plan${\lrcorner}$ consist of 47 projects include national level. For the purpose of third NGIS plan, diverse problems suggested on spatial information computierization, application, distribution. Secondly, we conducts an analysis of national geographic information demand. According to the analysis results 'cyber geospace' is the key issues in near future. In order to construct the ${\ulcorner}$Integrated Digital Territory${\lrcorner}$ in the 21st Century, the current promoted project for the national geographic information constuction needs to be more developed. In this regard, it is necessary to implement ${\ulcorner}$Integrated Digital Territory${\lrcorner}$, enhancing the usability of NGIS, creating the 'cyber geospace' and intelligent territory.

National Geographic Information Systems(NGIS) started from 1995 has greatly contributed to building GIS infrastructures and developing GIS industries. To evaluate effectiveness and achievement of NGIS, it is required to build a policy evaluation model for NGIS. This study examined prior research works on GIS policy evaluation system and analyzed limitations of them. Then, it established a model for NGIS evaluation system. The study will contribute to removing unnecessary and duplicate efforts in NGIS project by providing an efficient mean for relict evaluation. It will also heir successful implementations of NGIS.

Since 1995 the Korean Government has implemented the Master Plan for the National Geographic Information System(NGIS) to build up the National Spatial Data Infrastructure. This paper aims to evaluate the NGIS on the scope of National Land Use Policy and Urban Planning and to suggest the way to solve the current problems of National Land Use.

During the first and second NGIS projects by the Korean government, The first one (1995~2000) was limited on constructing geographic information and the second (2001~2005) was focused on circulation and practical use of geoinformation from the result of the first project. In the latter half of 2nd NGIS project, However, the geographic information from the NGIS projects have not been renewed even though there were significant geographical changes. The accurate renewal of geoinformation is a matter of great importance to the next generation industry (e.g. LBS, Ubiquitous, Telematics). In this respect, it is time to update the geographic information in the latter half of the second NGIS project. Therefore, It is not only important to build an accurate geoinformation but also rapid and correct renewal of the geoinformation. NGII (National Geographic Information Institute) has been studying for improvement of digital map that was constructed by the result of the 1st NGIS project. Through the construction of clean digital map, NGII constructed Framework Data to three kinds of formats (NGI, NDA, NRL). Framework Data was contained to other database, and provided the reference system of location or contents for combining geoinformation. Framework Data is consist of Data Set, Data Model and UFID (Unique Feature Identifier). It will be achieved as national infrastructure data. This paper attempts to explore a method of the update to practical framework data with realtime geoinformation on feature's creation, modification and destruction managed by 'Feature management agency' using UFID's process. Furthermore, it suggests a method which can provide important data in order to plan the Framework update with the land change ratio.

As the results of the information project, manufacturing of the digital map and various thematic maps of the national land has been completed. Furthermore, it is necessary to organize a systemized management system, which can control and utilize all artificial features (e.g. buildings, roads, bridges etc.) as well as natural geographic features (e.g. rivers etc). Howener, it has difficulties in managing NGIS as a unified system, because of the discordance of DB of each geographic management organizations. Therefore, this study has been conducted to apply to the system and method providing geographic UFID that can be a key in order to managing, searching and utilizing geographic and artificial features and that makes it be able to estimate the location with the only identifier. Moreover, the system and method, providing geographic UFID, applies to systemized management of NGIS DB as well as consistency of information.

National Geography Institute(NGI, National mapping agency) has been producing national basemap in automated process since middle of 1980's toward the systematic and efficient management of national land. In 1995, Korean government initiated a full-scale implementation of the National Geographic Information System(NGIS) Development Plan. Under the NGIS Development Plan, NGI began to produce digital maps in the scales of 1:1,000, 1:5,000, 1:25,000. However, digital maps of 1:250,000 or less scale, which are currently used for national land planning, were not included in NGIS Development Plan. Also, the existing laws and specifications related to digital maps of 1:250,000 or less scale are not clearly defined. Therefore this study proposed a feature classification system, which defines features that should be represented in digital map of 1:250,000 or less scale.

Korean government has conducted National Geographic Information System(NGIS) project since 1995. The NGIS was set up and directed by central government to stimulate the growth of GIS field in Korea. Thanks to the project, all aspects of GIS in Korea has been rapidly developed. However, this government-led strategy now reveals some limitations on the advancement of GIS in Korea It is time to prepare new approaches for the further development of GIS in Korea. This study aims at introducing the concept and model of National Spatial Data Infrastructure(NSDI) and suggesting strategies fir it. By doing so, this research attempts to reestablish the role of government and draws new policy directions for the NGIS.
