Imposing geologic interpretations on computer-generated contours using distance transformations

Developing practical computer programs to impose geologic interpretations on computer-generated contours has proven to be difficult. Today, complex data transformations, tedious contour editing, or both are used to achieve that goal. This paper introduces a new program for incorporating high-quality geologic interpretations into computer contouring. The program is robust, easy to implement, and easy to explain to potential users. The computational complexity of the program is high, but the results are worth the price.
