The u-GIS national land information providing technology is the technology which maximizes the application of u- GIS data through the national land information platform technique of the next generation web and provides a user with the on-demand national land information in the ubiquitous environment. Recently, as the environment emphasizing the web as a platform 'Web 2.0' emerges, the where 2.0 which is paradigm is diffused in the spatial information area. And the Geo-spatial Web technology develops in a center. Moreover, it is changed to the open platform of the user participation trend. And the consumer of the geo-spatial information is changed to the end-user center from the public institution. The geo-spatial technique is technologically faced with the new challenge. In this paper, we analyze the technical tendency about a paradigm, And we present the u-GIS national land information platform technique, the u-GIS national land information visualization technology, the u-GIS national land information GeoDRM integrative technique, and the u-GIS national land information mobile application technology as the essential elemental technology for overcoming this.

In open GIS environment, a GIS client can access spatial data in different types of GIS sowers with the same Interfaces. This means that open GIS components software ensures the interoperability throughout the heterogeneous GIS servers. The user response time, however, tends to be increased, if the client makes use of the standard interfaces for data accesses that can ensure interoperability. This is because the format of spatial data accessed from a specific GIS server must be transformed into common format, such as Rowset in OLE/DB, which is compatible with the standard interfaces. In this paper, we develop efficient techniques for data buffering in GIS client to reduce the response time. We design the buffer management method, which Is based on the space partitioning, and Integrate buffer management components into MapBase, an open GIS component software. And we also, show that buffer management proposed in this paper yields significant performance improvement in GIS client.

Korea's GIS market has been proliferating since the 1990s, but still its scale and the structure require overall rearrangements. Recently as the needs and initiatives from central and local governments go stronger to drive 'u-City(ubiquitous City)' developments, there are much more demand of spatial information from sectors like city management, construction, environment and so on. Through the merge between GIS and the advanced Information and Telecommunication Technology, the introduction of new Ubiquitous IT is swiftly changing GIS market environments, so the GIS industry is to be prepared for this trend. The pioneering developments of Ubiquitous-related GIS technologies are expected to highly boost spatial data and related industries, and the pre-occupancy of those technologies in the world would enable the expansion of overseas export market. In the context of these epoch-making chances, by looking into the actual status of GIS industry, this study is to investigate the actual accomplishments to foster the GIS industry through Korea's National GIS Master Plan. Thereby, impending issues will be discussed to provide useful problem-solving suggestions.

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.

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.

Many GIS systems are not to be trusted becuase many GIS project managers often fail to notice importance of GIS data Construction. With this reason, it is a lively discussion on GIS administration system's adaption. The definition of GIS administration system is not clear, but GIS administration system generally is devided information system administration, audit guideline for the data construction of GIS. Audit guideline for the data construction of GIS. GIS data construction's goals are logical and reasonable action policy of GIS data construction in widespread filed, the other goal is creation of product to the purpose exactly. Audit guideline for the data construction of GIS is composed of optimum of GIS data construction's planning, optimum of GIS data construction's activity, optimum of GIS data quality management, optimum of consultations of GIS data construction, GIS data audit. GIS data audit is the phase of detection product's potential error in each level. GIS data audit is composed of filed examination or filed verification, examination with the naked eye, screen verification, program verification, auto verification. GIS information system's efficiency is linked with auto verification system's function variety, accuracy. this paper offer introduction of Audit guideline for the data construction of GIS, efficient auto verification program

The purpose of this paper is to examine trends of the GIS education in the school's education of the USA, especially the geography education, which the application of GIS is activated in the life. In addition, in this paper are explored possibilities of GIS education in the geographical education of Korea throughout the consideration of the USA case. There are some backgrounds of the activation of GIS education in the USA, They can be characterized as (1) the achievement of the validity between the geographical importance in the realm of the national policy and GIS education, (2) offering standard indications for GIS education and gradually minimizing school teachers' work-loads, (3)the establishment of the network of GIS stake-holders and their cooperation, (4) the attraction of school students through case study-centered education, and (5) the share of GIS education-related information. These shall be considered to introduce actively GIS education into the geography education in Korea.

It is possible to design a strategy for expanding the applications of GIS by identifying why social science researchers use GIS. This study analyses motivating factors for the researchers to utilize GIS and their satisfying factors towards the result. It is based on survey results which was answered by social science researchers at national research institutes and local governmental research institutes in South Korea in the perspective of merits of applying GIS, level of GIS usability and experienced effectiveness of applying GIS. Analysis result reveals that motivating factors to researchers applying GIS are correlated with efficiency in their research and satisfying factors are correlated to the usability. Then, we induced a fact that motivative factors for applying GIS is not related to the satisfaction of that. It may be a reason which researchers use GIS less applying in social science fields. As a result, it is necessary to connect the motivating and satisfying factors to further expand GIS applications.
