• (a) Distances AC and BC are measured, and C is plotted
as the intersection point of two arcs with centers A and
B and radii from the measured distances.
Introduction
• (b) Perpendicular CD and distance AD or BD measured
and C is plotted by the use of a set square.
• (c) Distance AC and the angle BAC are measured, and C
is plotted by means of a protractor.
• (d) Angles ABC and BAC are measured, and C is plotted
by a protractor or by solution of triangle ABC.
• (e) Angle BAC and distance BC are measured, and C is
plotted by a protractor.
• iii) City surveys: These surveys are carried out for laying
of plots, construction of roads, sewer lines, water supply
system etc.
Classification of surveying
• 5. Plane and Geodetic Surveying:
• a) Plane surveying.
• b) Geodetic surveying.
