A method is presented which describes rational digitization and efficient treatment of a geologic map. An oriented graph, S, the arcs of which are associated with stratigraphic boundaries and imply a difference in the topological nature of the map if it includes faults, is used. From S, we deduce other graphs: a dendrogram which is used to structure the data and a graph which summarizes the geologic properties of the map. This structure is useful for graphic reconstitutions on a plotter or screen, and for quantitative correlation and calculation of dips, surfaces, and volumes. [ABSTRACT FROM AUTHOR] |
