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