10.11.1. Instrumental Errors

Try these first

1. 1.

   What is instrumental error in hydrographic surveying?

   Hint

   Think about what can go wrong with measurement tools.

2. 2.

   Why is calibration important?

   Hint

   Consider the relationship between accuracy and safety.

3. 3.

   What are instrumental errors primarily caused by?

   • User error
   • Calibration errors
   • Environmental factors

   Hint

   Consider who or what is responsible for the inaccuracies.

4. 4.

   Calibrating instruments is important for:

   • True
   • False

   Hint

   Think about the consequences of using uncalibrated instruments.

5. 5.

   A hydrographic survey reports a depth of 20 meters due to a calibration error that actually measured 23 meters. What could be the implications for maritime navigation and construction projects?

   Hint

   Consider the safety and operational aspects of incorrect measurements.

6. 6.

   Design a workflow for a hydrographic surveying team that ensures regular calibration and maintenance of equipment. What steps would you include?

   Hint

   Think of establishing a routine and keeping detailed records.
