| Abstract: | Microcomputer graphics should be an essential tool for geologists. The CROSSX program serves as a computer-assisted drafting tool for geologic cross sections on microcomputers running the MS-DOS operating system with an Enhanced Graphics Adapter (EGA). CROSSX combines two inputs: digital elevation model, available already digitized; and local stratigraphic column. The user can create templates for final hand drafting of sections, and include folds, faults, and uniformly dipping stratigraphy. CROSSX automates tedious parts of cross section preparation by drawing the topographic profile, calculating apparent dip in the line of section, and scaling each unit for the chosen scale. Although the computer cannot replace the geologist's judgment, it can handle details and perform many checks to help the geologist better spend time on interpretation.This paper was presented at Emerging Concepts, MGUS-87 Conference, Redwood City, California, 13–15 April 1987. |
