When they are on the edge of a single circle, take the
following measures.
·
Move the instrument station as close as possible to the
center of the triangle.
·
When the distance between known points are fixed. When
distance between station point and known points are
increased, their included angle are lessened, the known points
can easily be on the edge of a single circle. It is impossible to
calculate the coordinates of the instrument station if the
included angle between the known points is too small.
16. Area Calculation
It is also possible to calculate the area of land enclosed by three or more known points on a line by manually
inputting or reading the coordinates of the points.
Coordinates(Known value)

P2 (N2, E2)
P3 (N3, E3)
P4 (N4, E4)
P5 (N5, E5)

Area is calculated by observing the points on a line enclosing an area in order or reading in the previously
registered coordinates in order.
