Hi all, Recent discussion of "waterfall plots" prompts me to pose a somewhat related query. I work with digital elevation model data sets from the U.S.G.S. to produce contour maps, using ListContourPlot under Mathematica 2.2. I would like to be able to produce old-style quasi-contour maps using "hacheurs," in which the contours themselves are not drawn, but instead, line segments at right angles to the contour lines, of lengths inversely proportional to steepness of slope (short hacheurs->steep slope). Any ideas? Russell Towle Giant Gap Press: books on California history, digital topographic maps P.O.
