An arrangement and organization of geological data which are observed and collected in fieldwork play an important role in various geological research. Recently the Geographic Information System(GIS), spatial data storage tool, is applied to geological analysis and geophysical exploration. But, there is a few study for application of geological data to GIS. This research is to definite exact geological dataset in GIS data structure and is to develope a program the ARC GEOLOGY, which stores, edits and manages them.
Various geological terms, for example fault, formation and rock type etc. were classified attributes (point, line and polygon) in GIS and defined an importance and factor for geological analysis. On this framework, ARC GEOLOGY programmed in Windows NT using Arc Macro Language (AML). ARC GEOLOGY is composed of base map, geological point, line, polygon and other layers. This program is the ⑴ basic system for printing maps, ⑵ GIS-based database for geological analysis, and have ⑶ functions of an adoptable map-displaying ⑷ computing and conversion of geological maps. It is possible to input, edit, search and visualization of the geological map and to display 2D or 3D maps of them and layering several maps.
This program helps to work exact and qualifiable investigation in field and to solve specific geological problems through various graphic and analysis functions.
