The major reason that spatial data warehousing has attracted a great deal of attention in business GIS in recent years is due to the wide availability of huge amounts of spatial data and the imminent need for turning such data into useful geographic information. Therefore, this research has been focused on designing and implementing the pilot tested system for spatial decision making. The purpose of the system is to predict targeted marketing area by discriminating the customers by using both transaction quantity and the number of customer using credit card in department store. Focused on the analysis methodology, the case study is aiming to use GIS and clustering for knowledge discovery. The system is a key section of the research of multi-dimensional and spatio-temporal analysis in the internet environment.

Recently software industry in GIS(geographic information system) becomes an interesting issue by performing a large scale of national GIS application development as well as even small unit of FMS(facility management system). Also, there exist many cases to combine GIS with various business domains such as MIS(marketing information system), CNS(car navigation system) and ITS(intelligent transportation system). In this situation, in order to develop an efficient and useful GIS application for a short term, there must be a deep consideration of not only developing GIS component but also managing GIS component. In fact, even though there exist many certain components having high reusability, excellent interoperability and good quality, their reusability may be reduced because of their difficulty to access in a certain repository. Therefore, it is important to classify components having common characteristic based on their particular rule with reflecting their functionality and non-functionality before cataloging them. Here, there are two non-functional classification categories discussed such as GIS content-dependent metadata and GIS content-independent metadata. This cataloged components will help application developers to select easily their desired components. Moreover, new components may be easily producted by modifying and combining previous components. Finally, the original goal of all this effort can be defined through obtaining high reusability and interoperability of GIS component.

The KDE (Kernel Density Estimation) technique in GIS (Geographic Information System) has been widely used as a method for determining whether a phenomenon occurring in space forms clusters. Most human-generated events such as traffic accidents and retail stores are distributed according to a road network. Even if events on forward and rear roads have short Euclidean distances, network distances may increase and the correlation between them may be low. Therefore, the NKDE (Network-based KDE) technique has been proposed and applied to the urban space where a road network has been developed. KDE is being studied in the field of business GIS, but there is a limit to the microscopic analysis of economic activity along a road. In this study, the NKDE technique is applied to the analysis of urban phenomena such as the density of shops rather than traffic accidents that occur on roads. The results of the NKDE technique are also compared to pedestrian networks and road centerline networks. The results show that applying NKDE to microscopic trade area analysis can yield relatively accurate results. In addition, it was found that pedestrian network data that can consider the movement of actual pedestrians are necessary for accurate trade area analysis using NKDE.

The motivation of this paper comes from a recognition that GIS educators in the private and public sectors are faced with both an opportunity and a dilemma. As the GIS vendors move to open systems which can be integrated with many traditional operations, the use of spatial data and analysis will become widespread throughout business, government and education. Hence the need for standardization in GIS fields is expanding rapidly. Especially non-standardized terminology of GIS prevents GIS-users from communicating among the GIS application fields. This paper will assist this shifting foundation by providing terminology control procedures for ISO/TC2ll family of standards and KS(Korea Standards) information terminology and make recommendations for the improvement and harmonization of terminology.

The damage scale and damage area in the coast have been increased dramatically because of calamities such as typhoon. tidal wave. flood and storm. Especially. 409 cases. which reach to about $40.9\%$ of natural disasters of 1,000 cases for the recent 15 years have happened on coast area. More than $40\%$ of natural disasters also occurred every year is happening in coastland. Therefore, there is a great need to construct all related GIS database such as atmospheric phenomena (typhoon. tidal wave, flood and storm). harbor facility, harbor traffic and ebb and flow. Furthermore. the certain system should be developed and integrated with NDMS (National Disaster Management System) by using 3D web GIS technology. In this study. the coast disaster area management system was designed and developed by using 3D web GIS technique so that the coast disaster area could be monitored and managed in real time and in visual. Finally. the future disaster in coast area could be predicted scientifically.

Recently, as a part of NGIS project, cultural-assets digital map is produced by cultural properties administration and local autonomous entities. Cultural-assets unified GIS(Geographic Information System) is essential to cultural properties managers and other organizations which are executing land related business for appling it at planning stage. With explosive national land developments, it has been obligated to implement surface survey by the cultural properties protection Art. In this paper, we develope a MSSS(Mobile Surface Survey System) and central GIS management system using CDMA wireless network, real time DGPS and C/S GIS technologies. And we suggest a construction-plan of cultural-assets digital map drawing and managing system by Archaeologist using developed system by this study.

With the recent surge of public interests in real estate markets, public demand on cadastral information including cadastral maps has been increasing rapidly. However, the torrent system that provides cadastral information falls far short of meeting public demand due to its main focus on government users. In order to reduce the gap between public demand and supply of cadastral information, a new business model is needed that fulfills public needs and at the same time generates profits for service providers. The main objective of this paper is to identify a potential business model that satisfies the above conditions. To achieve this objective, we have explored the unmet needs of public users in real estate transactions and examined whether the unmet needs can best be served by the resources and capabilities of Korea Cadastral Survey Corporation. Then, we have crafted a detail business model i.e., Syndication model, that includes value propositions, resource maps, and revenue and cost estimations. Finally, a plan is proposed to serve government users better with the financial surplus from the proposed business model. The results of this study can be useful for other similar areas including GIS, ITS and telematics, academically as well as practically.

Spatial information is essential for administrative affairs. So many Administrative Information System(AIS)s and Geographic Information System(GIS)s have been implemented at local government to support administrative affairs. AIS deals with document based information, and is not designed to use map information. Also, various information is not matched, because address systems for AIS and coordinate system for GIS are different. Therefore, existing AIS and GIS are not suitable for linking administrative affairs and spatial information. This paper deals with the enterprise architecture for local government to support the linkage of administrative affairs and spatial information. Enterprise architecture in this paper is composed of business architecture, data architecture, application architecture, and technical architecture. Each architecture is designed up to planner's and owner's level. Detail structures of each architecture follow the practical guidance for applying e-government enterprise architecture in Korea. Business and data architecture are applied to transportation administrative affairs.
