LSIT Measurement Technology 2

Question 1

What is a closure ratio?

Accepted Answer

Ratio of misclosure to total distance; acceptable typically 1:10,000+

Answer

This expresses accuracy relative to total distance.

Question 2

What is the method of least squares?

Accepted Answer

Minimizing sum of squared residuals to find best-fit survey values

Answer

This optimally distributes errors across all measurements.

Question 3

What is the coordinate method for area?

Accepted Answer

Using boundary point coordinates with cross-multiplication formula

Answer

Mathematical formulas provide precise area from coordinates.

Question 4

What are control surveys?

Accepted Answer

Establishing precisely located reference point networks for detailed surveys

Answer

These create the reference framework for other surveys.

Question 5

What is construction staking?

Accepted Answer

Placing stakes on ground to guide construction per design plans

Answer
