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 this paper, we implement a spatial data management system which is based on GIS technology. GIS technology is tightly related with spatial information and will be important method for future information-oriented society. The implemented system collects and manages spatial data. In the implementation, we use PostgreSQL DBMS. We also implement magnification, reduction, movement and search functions in the system.

The purpose of this paper is to analyze the activation methods of GIS industries through GIS industry current issue analysis in Korea to provide as following. First of an in order to analyse current GIS industries, there are three divisions as follows: existing GIS industry, new technology GIS industry, and commercial GIS industry. The existing GIS industry includes survey industry, municipality UIS and remote sensing. The new technology GIS industry has telematics industry, LiDAR industry, ubiquitous industry, LBS industry, internet, and u-city industry. The commercial GIS industry consists of civilian request GIS industry and spacial data distribution industry. The national geographic information industry contains problems and directions of the 1st, 2nd NGIS and 3rd NGIS plan direction policy. These classified GIS industries present various problems of policies and invaluable results for the future GIS industry activation directions as follows: Presence of the GIS contents technologies win be the most important core for the GIS industry activation related to IT839 policy of the government in Korea.

Technology of GIS evolved as a means of assembling and analyzing diverse spatial data. Many systems have been developed, and almost of systems are proprietary. There is a lots of lack of interoperability and reusability between them. This paper describes the development of Open GIS component software. The developing system have an end in view of GIS tool software which is interoperable and reusable. To increase the interoperability and reusability, the system is based on the OGC(Open GIS Consortium)'s Open GIS Simple Features Specification for OLE/COM. The OGC's specification is announced to increasing the full interoperability of various geospatial data and geoprocessing resources. With the Open specification, component based software ensures the reusability. We implement three kinds of component: Geometry component, Spatial Reference System Component, and MapBase Component. The first two components are compatible to the OGC's specification and the third one is designed to GIS tool software for variant GIS applications. The Open GIS component software system is developed on object-oriented computing environment, ATL/COM and Visual C++. As we made application programs using Visual Basic, the advantages of component based Open GIS software was proved.

GIS is a integrated information system that is designed for collect, store, renovate, space analysis, representation effectiveley of information which was formed by space information of features such as mountain, pavement, building , river, communiction, power, gas line, natural resource. the core technology of CIS are the open GIS component technology, spae information circulation, advanced GIS application technology and space data forming technology. In this study, GIS core technology development, market and standization are represented.

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 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.

MediaGIS is a concept of tightly integrated multimedia with spatial information. VideoGIS is an example of MediaGIS focused on the interaction or interaction of video and spatial information. Our suggested GeoVideo, a new concept of VideoGIS has its key feature in interactiveness. In GeoVideo, the geographic tasks such as browsing, searching, querying, spatial analysis can be performed based on video itself. GeoVideo can have the meaning of paradigm shift from artificial, static, abstracted and graphical paradigm to natural, dynamic, real, and image-based paradigm. We discuss about the integration of video and geography and also suggest the GeoVideo system design. Several considerations on expanding the functionalities of GeoVideo are explained for the future works.

SWAT includes a lot of parameters related with geography, hydrological time series, land management and water pollution, etc. So, it needs many spatial, non-spatial and time series data to run SWAT. If SWAT is operated in conjunction with GIS, we can use database which includes model input data and do all the processes which covers data creation, model input and analysis of simulation results in a system. The objective of this study is to develop HyGIS-SWAT which is the interface system to couple the SWAT model and HyGIS. To achieve this object, system operation process based on HyGIS-SWAT data model is evaluated and databases are designed and established. As a result, HyGIS-SWAT prototype system is developed. HyGIS data model and HyGIS-Model operation process can be applied effectively to the development of HyGIS-SWAT. The technologies from this study can be used as base technology to develop another HyGIS application which connect HyGIS with models.
