In topographical surveys, you measure distances along straight lines. These lines either join two fixed points or run in one direction starting from one fixed point. They are plotted in the field with pegs, pillars or ranging poles.

Always measure distances as horizontal distances. You may have to measure on ground which has no slope, or only a very small slope that is less than or equal to 5 percent The distance measured on this type of ground will be equal to or very close to the horizontal distance. When the slope of the terrain is greater than 5 percent, however, you will have to find the horizontal distance. To do this, you must either correct any measurements you made along the ground or use another method of measurement (see following sections). Unlevelled ground also requires particular methods of measurement.

• take 100 normal steps on horizontal ground, starting with the toes of your back foot from a well-marked point, A, and walking along a straight line.
• mark the end of your last step with peg B, at the toes of your front foot.
• measure the distance AB (in metres) with, for example, a tape and calculate your pace factor PF (in metres) as follows:
