9.10.3. Accuracy Classes

Try these first

1. 1.

   What is the precision range of Class I accuracy?

   Hint

   Think about what is required for engineering projects.

2. 2.

   Which class is used for general topographic surveys?

   Hint

   This class has a wider margin of error.

3. 3.

   What is the precision of Class I accuracy?

   • ±2–5 mm
   • ±10–15 cm
   • ±0.5–1 m

   Hint

   Recall the need for precision in engineering applications.

4. 4.

   True or False: Class III is adequate for detailed architectural projects.

   • True
   • False

   Hint

   Consider the implications of using a lower accuracy class.

5. 5.

   Design a short project proposal that requires the use of all three accuracy classes. Explain the rationale for each class choice.

   Hint

   Think about where accuracy matters most.

6. 6.

   Critique a hypothetical project where Class III accuracy is used for critical engineering work. Discuss potential issues.

   Hint

   Consider the consequences of insufficient accuracy in sensitive areas.
