topographic-skills.pdf (Page 1 of 2) A topographic map shows the varying shapes, heights and slopes of a landscape using contour lines .That’s why they are so useful for bushwalking, property mapping and even town planning. Contours are lines that connect points at the same height above sea level and are plotted using vertical aerial photographs.
Topographic map diagram 2 . The topographic map above shows a hill with a peak elevation of 2574 feet above sea level. Four valleys and four ridges radiate from the peak. 1. Using a blue colored pencil, draw a line along the middle of each valley, showing where streams would run if there were a stream in each of the valleys.
