HOW TO USE LINE TOOL TO CREATE HACHURE LINES?

I am a mapmaker, and I need PhotoShop to make hachure lines for me automatically. Hachures are the old-fashioned representation of ridges, by means of short, parallel lines, packed close together, which go down each side of a topographic ridge. I have many features which I need to label this way over the top of an airphoto. I would like to use the Line Tool to draw the ridge lengthwise, then have PS create the small, parallel lines across the line I draw. These are sometimes referred to as "caterpillars" because they look like that. Thank you!

    Illustrator’s Scatter Brush would be another option.

    I tried to carry out what you suggested, but did not succeed, and solved the problem in another way. I think the issue is that I’m not yet an Illustrator user at all, and in fact, have only used the Adobe PS drawing capabilities for very simple annotations over airphotos. If you felt like putting together the whole sequence (with more guidance), I could certainly use it next time, but you’ve already done more than your share! Thank you!

    From your name, I’m guessing that you may be in Germany. I lived there almost eight years, and loved it!

    Christophe used one of the Calligraphy brushes which you can 'Append' by clicking on the little cog icon after right clicking to show the brush preset panel.  Note the brush outlined is vertical.

    Two settings need to be changed.

    1) Angle jitter needs to be set to Direction in Shape Dynamics

    2) Spacing needs to set to give the required line density.

    It is then a simple matter of drawing the work path with the Pen tool, and Stroking that path.

    Right click the work path and make sure Brush is selected, and that the brush size is about right, and click OK.  Note Simulate Pressure should be turned off.

    Having done it once, you can repeat this process by clicking on this icon at the bottom of the paths panel
