The State-of-the-art Digital Geologic Mapping in Korea Towards UML-based Data Modeling Approach by Kiwon Lee, Department of Information System, Information and Computer Science Division, Hansung University, Korea, No-Wook Park*, National Geoscience Information Center, Korea Institute of Geology and Mineral Resources, Korea, and Kwang-Hoon Chi, National Geoscience Information Center, Korea Institute of Geology and Mineral Resources, Korea In Korea, national digital geologic mapping has been carried out since the late 1990s. This approach is a part of so-called NGIS (National GIS) of Korea, and geologically mappable database information is one of nation-covering thematic mapping. Several further researches after the first year project for Korean digital geologic mapping will be followed. Especially, to provide basic information from a variety of sources in a consistent, applicable, and searchable structure, digital data modeling approach is needed. Among geo-data modeling approach, the data modeling in UML can provide: sufficient semantics and notation to address a wide variety of contemporary modeling issues, extensibility mechanisms for the future modeling approaches. In this paper, first, we introduce general review of the state-of-the-art Korea national digital geologic mapping and concepts of geo-data model with data modeling aspects are addressed, and then case histories for geo-data modeling and several approaches for data modeling in GIS application fields are discussed. Lastly, tentative conceptual geologic data modeling by using UML(Unified Modeling Language) of OO(Object-oriented) concepts is attempted. Through this approach, the main benefits for standardization and implementation lineage with conceptual model in consideration to reusability are expected.
