  • The role of a GIS as a tool for a national information infrastructure can best be fulfilled once GIS standards are implemented. In this paper, we have identified what the contents of GIS standards in other countries are, and what should be the future direction for implementing a nation's GIS standards. Based on a detailed review on GIS standards in the USA, Australia, Japan and the United Kingdom, we derived the following: (1) A nations's GIS standards should include both geographic information content standards and geographic information service standards: (2) A nation's GIS standards should be a profile of ISO GIS standards: (3) Each GIS standards should be developed on the bassis of the Entity-Relationship Model using Unified Modeling Language: and (4) Experts in GIS should pay much more attention on studies on GIS service standardization. As for building the national GIS Standards for Korea, we recommend both GIS Content Standards and GIS Service Standards be simultaneously developed. GIS Content Standards include geographic feature content standard, feature classification standard, portrayal standard, rules for application standards, spatial reference model and terminology. GIS Service Standards include standards for data sharing such as metadata standard and transfer standard, quality standard, quality principle and portrayal standards.

  • The construction of the Geographical Information System(GIS) is continuously in progress, and with the diversification and complication of the system, the importance of its audit is further deepened. At this point in time, the information system audit has been obligatory as it has been stipulated in law, and the GIS audit has come to follow the criterion of the information system audit since it belongs to the information system audit category. However, it was found that there was a difference between the current information system audit standard and the former GIS audit standard, and the audit checking items for the efficient GIS audit is necessary. For this reason, this paper surveyed the characteristics of GIS in accordance with this necessity, analyzed the GIS audit checking items found in the audit performance guideline of the GIS audit standard, and studied the GIS development methodology through the related literature. In addition, this paper also elicited and proposed the audit checking items for the efficient GIS audit based on the findings of this paper. Finally, this paper confirmed the efficiency of the GIS audit checking items proposed here through the comparison of the actual cases of GIS audits.

  • This study is to develop the direction of the development of the next-generation mapping of marine information required to develop a base of the utilization localization of maritime production tools. The GIS data-processing products and technologies currently used in the Korea's marine sector depend on external applications which is renewal costs, technical updates, and unreflected characteristics. Meanwhile, the S-100 standard, the next generation hydrographic data model that complements S-57's problems in marine GIS data processing, was adopted as a new marine data standard. This study aims to present the current status and problems of marine GIS technology in Korea and to suggest the development direction of GIS software based on the next generation hydrogrphic data model S-100 standard of IHO(International Hydrographic Organization). S-100-based marine GIS localization technology development and industrial ecosystem development research is expected to scientific decision-making on policy issues that occur with other countries such as marine territory management and development and use of marine resources.

  • The most important thing for the national GIS development is considered to be the standardization, especially the development of the standard coding scheme for the GIS features and attributes. The comparative study on those of the several international transfer standard is, therefore, very meaningful. In this paper we analyzed the features and attributes coding catalogue for the three different exchange standards; SDTS, DIGEST and SP-57. And also the new coding scheme is proposed as the unified standard frame to be used for all the GIS related application and the digital product.

  • As the networks proliferate all over the world and the application of the geographical information increase recently, the importance of effective access and exchange of GIS data is recognized. However, existing GIS data are generated by many different organizations without proper standard methodologies and data exchange facilities such as clearing houses are being operated on different DBMS with their own schemata. It makes difficult for users to access and utilize the GIS data even the data are open to public. In this research, we provide the users a search system that interfaces heterogeneous repository systems. In order to interact heterogeneous DBMS we utilize the metadata interchange standard (XMI) from OMG.

  • The inner space of building is increasingly becoming complex as urban activities increase in variety, and the actual space size also increases. This trend necessitate the utilization of three dimensional position information within the inner space of buildings. Standard GIS web service technology and visualization technology are applied to 3D inner space building data to share these information for better decision making in building related applications such as fire evacuation, facilities management and market analysis. This study aims to effectively model and visualize the three dimensional space of building interiors in the GIS aspect, and to be able to share the information through standard GIS web service. The various elements of inner model was assigned and stored into pre-designed spatial database tables respectively. GIS web server was then configured to service the database which was populated with 3D inner model data. On the client side, 3D visualization modules was developed using a 3D graphic rendering S/W engine.
