The objective of this paper is to develop a cartographic model for water tank suitability for small forest fire extinction using GIS. Various digital maps were created using CAD & GIS for Amnam urban park, which is located in Seogu, Pusan city. The park had 4 small water tanks for fire extinction. The developed descriptive cartographic model identified the spatial effects of fire extinction due to the existing facilities. The prescriptive model to enhance spatial effects was developed for the determination and comparison of the effects of forest fire extinction due to the proposed facilities. This paper proved the techniques of GIS and cartographic modelling are significant for the suitability analysis of water tanks for small forest fire extinction.

The purpose of this paper is to select proposed waste facilities sites after consideration of relative importance of siting factors. From the literature review we have established the siting factors affecting selecting waste facilities sites, and constructed hierarchy of siting factors to evaluate the relative importance of the factors using Analytical Hierarchy Process(AHP). After mail surveying of expert group, we have analyzed the relative importance of siting factors affecting waste facilities. We have constructed Geographic Information System(GIS) of raster type, based on seventeen theme maps of siting factors on waste facilities, to select the proposed waste facilities sites after consideration of the relative importance of the siting factors for Gyongsan city, in Korea. After applying linear combination method, and factor combination method to overcome the methodological limitations of land suitability analysis, we have found five proposed sites, where intersected with proposed sites obtained from the two methods. From this research we have found that 1) methodologically, using GIS for selection of proposed waste facilities sites turned out to be highly useful, 2) application of relative importance of siting factors and two methods of land suitability analysis in selection of proposed waste facilities sites are pertinent enough to provide valid and reliable results, and 3) the research methods and approach employed in this research will be highly useful in site selection of other major facilities.
Analysing GIS Implementation Factors in Local Governments

As the digitization of maps in Korea has been completed in 1998, local governments begin to apply digital maps for their administrative convenience. In applying GIS to local administration, there are some important aspects to be considered such as technical aspect, organizational aspect and data managerial aspect. Using surveys to local governments, the study examines the implementation factors such as leadership, GIS organizational settings, human and financial resources, and education programs which are related to the applications of GIS to local governments in Korea. As a conclusion, the study proposes that organizational and human factors be combined harmoniously with technical factors from the beginning stage of GIS installation for the successful implementation of GIS applications to local governments.

This paper presents a KITSAT-3 image catalog browse and distribution system. The access time and easy-to-use concept of the system should be highlighted in order for satellite image users to browse and order the required images as quickly and easily as possible. In general, users want to enter their image search conditions in the simplest ways and to display the search results which can be interpreted intuitively. The KITSAT-3 image catalog browse and distribution system was developed to satisfy the users' requirements with the minimum system installation cost.

This study was carried out to investigate the feasibility of OTEC(Ocean Thermal Energy Conversion) operation, in the East Sea of Korea. Accumulated cruise data of NFRDI (National Fisheries Research and Development Institute) over the period 1966~1995 were used to locate appropriate spot by season as well as by latitude which would show the difference at least
or more between the surface layer and each depth of 50, 100, 150, 200, 250, 300, 400 and 500m. Our results showed that the coastal areas of Pohang city met the requirement of more than
difference for OTEC plant from August to October. In contrast, in case that
would be possible thermal difference to operate OTEC plant, most coastal areas in the East Sea including Pohang from June to December are potential candidates for this future energy source. Therefore, we present in this paper the first option to locate the best place for OTEC plant operation using Geographical Information System (GIS), which is currently used for multi-dimensional space analysis.
Database Design for an Urban Geographic Information System based on an Object-oriented Approach

The primary goal of the database design is to organize a large amount of data effectively in users and systems view point. Effective design of a database is very important for processing applications efficiently. In this paper, we discuss database design for an urban geographic information system that effectively maintains the cadastral and planimetric information. We first collect and analyze the requirements for the target urban geographic information system and then perform database design for these requirements. Our database design is based on the object-oriented approach that has rich expressive power and good reusability in comparison with the traditional relational approach. Especially, we employ the OMT, one of the most widely-used object-oriented models. We expect that our result would be helpful in building large databases for urban geographic information systems practically.
Design and Implementation of the Multi-level Pre-fetch and Deferred-flush in BADA-III for GIS Applications

Most GIS applications are read-intensive on a large number of spatial objects and when the spatial objects are composite objects, the contained objects within the composite objects are also accessed. In GIS applications, creation, deletion, and update operations on spatial objects occur very rarely, but once they occur they deal with a large number of spatial objects. This paper proposes the concept of the multi-level pre-fetch query to retrieve a large number of spatial objects efficiently, and the functionality of the deferred-flush on the newly created persistent objects into the database with the optimal performance, and presents the design and implementation details of those ideas into an object-oriented DBMS BADA-III while considering these characteristics of GIS applications. The multi-level pre-fetch query retrieves the objects that satisfy the query and the objects that are contained within the objects up to the level specified by users, and registers the retrieved objects on the client cache. The deferred-flush flushes a large number of composite objects that are created by the application with a minimal overhead of the server and a minimal number of communications between the client and the server. These two functionality are suitable for the applications that search or create a large number of composite objects like GIS applications.
