FREE LSIT Surveying Principles and Practices Questions and Answers
When performing a traverse survey, why is it important to close the traverse loop?
Closing the traverse loop involves returning to the starting point and comparing it with the ending point. This is crucial for confirming the accuracy of the traverse survey, as any discrepancies indicate errors in measurements that need to be corrected.
Which of the following is a common method for measuring horizontal angles in land surveying?
A theodolite or total station is commonly used to measure horizontal angles in land surveying. These instruments provide precise measurements of angles and distances, which are essential for accurate survey work and mapping.
In a boundary survey, what is the purpose of conducting a "title search"?
A title search is conducted to review historical records and legal descriptions related to property boundaries. This is essential in boundary surveying to ensure that the current boundaries are accurately established based on historical and legal documentation.
What does the term "bench mark" refer to in surveying?
A bench mark is a reference point with a known elevation that is used in leveling to determine the height of other points relative to this established reference. It ensures accurate vertical measurements and helps in maintaining consistency in elevation data.
What is the primary purpose of using a total station in land surveying?
A total station is an advanced surveying instrument that combines an electronic theodolite for measuring angles and an electronic distance measuring device for measuring distances. It is used to accurately measure and record the angles and distances between points, which is crucial for creating precise survey maps and plans.
