Geodesy 1 - Quiz II

Which of the following is NOT a type of geodetic control?

• Triangulation

• trilateration

• Horizontal control

• Oblique control

What is the main difference between triangulation and trilateration?

• Triangulation uses three points, while trilateration uses two points

• Triangulation measures angles, while trilateration measures distances

• Triangulation is used for horizontal control, while trilateration is used for vertical control

• Triangulation is more accurate than trilateration

Which of the following is part of the routine of a triangulation survey?

• Establishing a baseline

• Measuring angles and distances

• Adjusting the network

• All of the above

What is the principle of triangulation?

• The angles measured in a triangle can be used to calculate distances and positions

• The sum of interior angles in a triangle is always 180 degrees

• The accuracy of a triangulation network depends on the number of triangles formed

• None of the above

How are triangulation networks classified?

• Based on coverage

• Based on the accuracy requirements

• Based on the type of instruments used

• All of the above

The main purpose of a geodetic network is to:

• Measure angles and distances

• MEasure sides

• Provide accurate positioning and navigation

• None of the above

How are triangulation networks classified based on accuracy requirements?

• First-order, second-order, and third-order networks

• National, regional, and local networks

• Primary, secondary, and tertiary networks

• none of the above

In Triangulation, the triangles formed in the area is determined by measuring their angles.

• True

• False

Trigonometric leveling is the process of determining the different elevation of station from observed vertical angle and known distance using a spirit level

• True

• False
