FREE CST Survey Calculations & Coordinate Systems Questions and Answers

Question 1

What is the purpose of a traverse adjustment?

Accepted Answer

To correct for angular and distance errors

Answer

Traverse adjustment is a mathematical procedure applied to survey data collected from a traverse (especially a closed traverse) to distribute accumulated errors. This process ensures that the traverse closes geometrically and that the coordinates of all points are consistent. It improves the overall accuracy and precision of the survey.

Question 2

Which unit is typically used for angular measurements in surveying?

Accepted Answer

Degrees

Answer

In surveying, angles are most commonly measured and expressed in degrees, minutes, and seconds (DMS). This system provides a precise and universally understood method for defining directions and orientations. While radians and gradians exist, degrees are the standard for practical survey applications.

Question 3

What does the bearing N45°E indicate?

Accepted Answer

45 degrees east of north

Answer

A bearing is a direction expressed as an angle relative to either North or South. N45°E means starting from North and rotating 45 degrees towards East. This notation clearly defines the quadrant and the specific angle within that quadrant, providing a precise directional reference.

Question 4

What does 'azimuth' refer to in surveying?

Accepted Answer

A clockwise angle from north

Answer

Azimuth is a horizontal angle measured clockwise from a reference meridian, typically true North. It ranges from 0° to 360° and provides a unique and unambiguous direction for any line. Azimuths are widely used in surveying for defining directions and calculating coordinates.

Question 5

What does a coordinate system help establish in land surveying?

Accepted Answer

Precise spatial locations

Answer

A coordinate system provides a framework for defining the precise spatial location of points on the Earth's surface using numerical values (e.g., Northing and Easting). This allows surveyors to accurately map, measure, and represent land features in a consistent and repeatable manner. It is fundamental for geospatial data integration.
