  3. piece of paper A B 100 50 10 100 50 10 • Line up your piece of paper with a graph grid with 2 vertical axes. • The x-axis should be the same length as your outermost marks on you piece of paper • Draw the cross-section by writing the marks on the grid at the heights from the map. • Draw the line freehand that joins up the dots. x 120 x x x x x x x x x x x x 0 x

  4. From: Survey point 258677 To The lake at 277629 From River source 136646 To Survey Point 157698 Draw these cross sections from the Perisher Valley 1:25000 Topographic Map

  5. Calculating Vertical Exaggeration • See page 24 of your Atlas Workbook for a good explanation of this. Vertical Exaggeration (VE) = Vertical Scale (VS) ÷ Horizontal Scale (HS) Remember that your units of measurement must be the same 1cm:100m on a map must be changed to 1cm:10,000cm for the calculation.
