Module 7

A series of straight lines connecting successive points whose lengths and directions have been determined from field observations.

• Inverse

• Traverse

• Tranverse

• Intraverse

Purpose of Traverse? (Multiple answers)

• To locate and establish boundaries

• Supplementary horizontal control for topographic mapping surveys

• Location and construction layout surveys for private and public works

• Ground control for photogrammetric surveys

Where the positions of lot corners are referred from

• Traverse curve

• Traverse lines

• Traverse station

• Traverse corner

What is the difference between open and closed traverse?

Which are types of traverse?

• Azimuth Traverse

• Into the Traverse

• Interior Angle Traverse

• Reverse Traverse

Projection of a line onto a reference meridian (N-S line)

• Departure

• Multitude

• Atitude

• Latitude

Projection of a line onto a reference parallel ( E-W line)

• Departure

• Attitude

• Multitude

• Latitude

What is linear error of closure?

• Gap between true and measured position of original traverse station

• Difference between traverse line and traverse curve

• Total distance between all traverse lines

• The angle of initial traverse station

Bearing of side error

• Bearing of the closure line

• Bearing of the line from the final to the initial traverse station

• Bearing of the final angle

• Bearing the weight of surveyed building

Relative Error of Closure

• Ratio between closure and length of initial distance

• Ratio of the linear error of closure to the perimeter or total length of the traverse

• Ratio of the total distance to final distance

• Ratio of initial angle to final angle
