More Accurate Measurement of Land Area

Figure 13. Land area measurement—more accurate method

(shown as ‡ on the diagram above) at right angles from the line AD to points on the
field boundary where this changes direction. Note down the following readings (for
example):

D 92 0

81 12

64 18

26 5

a Annual/Biennial/Perennial

The first column of figures are the metre marks on the chain or tape measure (line
AD), starting at zero at point A. The second column of numbers are the distances
from the line AD to the field boundary.
Repeat this operation for AE, EF etc.

calculate the areas outside the triangles by counting the squares on the graph paper.
Repeat this calculation for AE, EF etc.

1. Use the same technique to mark and measure the area into triangles, as shown below:


2. Using either a tape measure or a surveyor’s metre chain measure all the lengths


3. Using the readings in 2. above (for DA), draw a scale field map on graph paper, and
