2 cards from this section. Quick, good the night before a test.
What is circle graduation error?
Think about how the Total Station measures angles.
How did surveyors traditionally correct circle graduation error?
Recall the common angles they started from.
What is the main consequence of circle graduation error?
Think about how measurement inconsistencies could arise.
True or False: Photo-etching eliminates circle graduation error completely.
Consider the nature of errors in mechanical instruments.
A surveyor repeatedly takes angle measurements from 90 degrees, 270 degrees, and others, averaging them to find the true angle. Explain how circle graduation error complicates this process and suggest ways to address it.
Consider the changes that technology brought into surveying.
Explain how advances in measurement technologies, such as software calibration and the use of high-precision instruments, align with the reduction of circle graduation error.
Think about how modern tools interact with traditional surveying methods.
