  • This paper demonstrates the prototype implementation of existing GIS operations using an integrated CA-GIS system where a CA simulator serve an analytical engine for GIS and compares the performance of the operations implemented here with the original ones. In addition, some new GIS operations that are not available in contemporary GIS are implemented and tested within the integrated system. It has shown that most of the local and focal operations were successfully implemented with CA-GIS and some operations written with the CA simulator showed better performance. New types of operations such as various shape filters, time-series filter, and diffusion operators were able to be implemented using the CA-GIS, which appears to be significant to enhance deficient analytical capabilities of contemporary GIS.

  • In this paper, we propose the application models and strategies of geospatial services registries for SOA in GIS web services. Recently. a number of SOA/web services are being developed for various commercial or public applications. However, geospatial SOA services are less used than general purpose SOA services, because GeoSpatial service registries has been neglected in many GIS applications even though GeoSpatial registries are essential component for open geospatial services. These problems are due to lack of researches for GIS registry usages. In this paper, we define the role player ill GIS SOAs, and develop the various GIS web service models among the players. Besides, we suggest the applications strategies of GeoSpatial services registries in the service models.

  • With the development and invention of computer and internet, GIS (Geographic Information System) has provided diverse services to users. Web 2.0, the next generation web, has been developed to create a new business by accumulating and structuring information from many users. The characteristics of Web 2.0 are blog, longtail distribution, SNS, DCC, collective intelligence, and so on. This study proposes a GIS 2.0 service model to maximize the introduction effect and use of GIS by the method that two-way communication and the participation of consumer, characteristics of Web 2.0, are used to build more practical GIS rather than providing spatial information in one-way and simple inquiry oriented way.

  • Rapidly evolving field of GIS and the social demand for university education to address the gap in the training of human resources, and future-oriented, engineering accreditation system based on the introduction of measures in the field of GIS is the need. In this thesis, the domestic and international undergraduate curriculum including University of Seoul's was analysed. A GIS curriculum of the domestic and abroad department course was analyzed. The present status of the domestic engineering accreditation and problems were analyzed and a desirable casting plan was shown through the abroad GIS related accreditation case analysis to analyze the validity of the engineering accreditation introduction of the GIS field. A standardized GIS curriculum was shown through the analysis of the core curriculum and the body of knowledge of the GIS field shown at the advanced of foreign countries all together. The industry-academia cooperation forum which made the Surveying and GIS related society the center by a political alternative, the construction of the caucus and the argument to execute this effectively are needed.

  • Considering that GIS (Geographic Information Systems) has not been widely adopted by teachers despite educators' considerable efforts to incorporate it into secondary education, if some teachers voluntarily participate in GIS in-service education without guaranteed benefits, those teachers deserve attention. This study investigates why teachers actively participated in a GIS staff-development program offered by Seoul National University in South Korea. Questionnaires were distributed to teachers and interviews were conducted. Results indicate that active participants are mostly young teachers who are expected to have had experiences with GIS during pre-service education. Teachers see the potential of GIS, but they also worry about several issues. Participating teachers' primary motivation was to learn enough about GIS to incorporate it into their teaching. Suggestions to facilitate the incorporation of GIS into education are provided.

  • This study was carried out as the Anyang creek water quality management using Geographic Information System (GIS) is the purpose of this pilot project to apply a GIS to environmental management field. Analysis of water quality data has been investigated using GIS with modeling of water quality management for the Anyang creek. The results of this study are summarized as follows: 1. The concentration of Mercury in sediment was increased rapidly nearby A26(Nightsoil Treatment Plant) and maximum was showed at A18 (Imgok bridge). Cadmium was increased rapidly at A35(Chulsan bridge). 2. River water quality management using visible computer system as GIS is effective to make decision for water quality management plan and database of environmental factors should be completed before applying GIS. 3. When water pollution accident is occurred in the river water system, pollutant source can be traced and analysed systematically using GIS to manage pollutants discharged into the river water system.

  • 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.

  • In the GIS literature, evaluation efforts have also been rare and unsystematic because of the difficulties in measuring impacts, and the lack of developed methodologies and evaluation criteria. Using a survey of the an ten local authorities in Korea, this research examines the benefits of using GIS and analyze the factors which affect the benefits of GIS in local authorities. Following are the major findings of this empirical research. First, most of the local authorities employees surveyed report improvements in operational and decision-making benefits. Second, factors influencing the benefits of GIS include political support and performance of the GIS system.

  • Over the past few decades, a considerable number of studies have been conducted on GIS(Geographic Information System) to process spatial date. As GIS comes to be used in many fields and used by many people, Web GIS which is a GIS system used on the internet, was proposed as a good tool to maintain the need. There is an increasing demand for Web GIS to provide more opportunity for users to manage and to analyze geotechnical data. This study mainly focused on the design and application of Web GIS particularly with geotechnical data, including design of efficient database structure for borehole data. A practical application of the Web GIS to tunnelling site has been successfully completed by the design of several analytical functions.
