| Abstract: | Geological symbols generally have the specific graphical features and geological significances and can be used to present some concrete or abstract objects in geological drawing. This paper analyzes and compares the computer graphical methods representing geological symbols ( especially lithotype notations ) with each other, and presents a new comprehensive method-graphical element composition method and its classified code scheme for the computer graphical definition of geological symbols based on analyzing various geological symbols. |
