Land Surveying 2 Diagnostic Test BTCC

Which of the following instruments is most commonly used for measuring horizontal and vertical angles in surveying?

• Total Station

• Theodolite

• GPS

• Laser Level

In land surveying, what is the purpose of creating a control network?

• To provide a reference framework for all future measurements.

• To calculate the elevation of mountains.

• To assess the quality of soil.

• To analyze water content in an area.

Which is the most appropriate way to present physical configuration data in land surveying?

• Population maps

• Contour maps

• Landform maps

• Histograms

What is the main advantage of using a total station in surveying?

• It can measure only angles.

• It combines distance and angle measurement in one device.

• It provides real-time weather data.

• It helps determine soil composition.

In recording physical configuration data, which of the following methods is most precise for larger areas?

• Tape and compass method

• GPS and Total Station

• Laser distance meter

• Pedometer

What is the primary source of error when comparing measured values to calculated values?

• Systematic error

• Human error

• Instrument calibration

• Environmental conditions

What term describes the closeness of a measured value to the true value?

• Precision

• Accuracy

• Error margin

• Resolution

When using a GPS, what kind of accuracy is typically expected under good conditions for civil use?

• 1-2 meters

• 5-10 meters

• 20-30 meters

• 50 meters

Which of the following affects the degree of accuracy in measurements?

• Time of day

• Length of the measurement path

• Instrument resolution

• Observer's age

Which method is most likely to increase accuracy when measuring a long distance?

• Repeating the measurements multiple times

• Using a string and ruler

• Estimating based on visual inspection

• Relying on weather data
