Abstract:
Geological information is considered as one of the fundamentally national knowledge to be used in various fields such as environmental pollution, ground disaster, natural disasters, exploration of natural resources and so forth. However, it is difficult to find out the interesting data of end users in geology and geological information has been losing as the time past. Also, geological data were produced by different institutes and researchers for a long time. Investigated and published geological maps until a recent date have used different geological boundaries, geological ages, colors, symbols, patterns and acronyms due to different period because of a long period of geological investigation and a number of investigator, and moreover, two adjacent geological maps are included many problems. Major area to solve these problems is data modeling. Present data modeling are disappeared modelers' idea and are distorted by programmers. This also enables data to play a part the level of in
formation but it is impossible to precede with the level of knowledge this problem occurred to be considered data model subsequently which is the most important coupling medium between modelers and programmers. This research prepares as data model, geological symbology and makes out GIS representation for digital geological map unit in Korea. To make out the spatiotemporal information system for geological map in Korea: first, we limited to geologic world to geological map in Korea. Second, we extract to rock units which is spatial object and to geologic time unit which is temporal unit from geological map. Third, we considered the standardization of geological term in Korean and English and make out geological terms for both spatial and temporal object. Fourth, we classify objects of geologic map unit and make a guideline about the specification of spatiotemporal ontology model for digital geological map unit. Finally, we construct the spatiotemporal retrieval system applied geological ontology model.
