Which type of leveling uses a level instrument to measure differences in elevation between points?
Answer: Differential leveling
Differential leveling uses a leveling instrument and graduated rods to determine elevation differences by reading backsights and foresights.
In surveying, the term 'bearing' refers to which measurement?
Answer: Direction of a line measured from north or south
A bearing is the direction of a survey line expressed as an angle measured from either north or south, toward east or west, always less than 90°.
What does GPS stand for in the context of modern surveying?
Answer: Global Positioning System
GPS (Global Positioning System) is a satellite-based navigation system that provides precise location and time information anywhere on Earth.
The closing error in a traverse survey is corrected using which method?
Answer: Least squares adjustment or Bowditch (compass) rule
Closing errors in a traverse are distributed using the Bowditch (compass) rule, which distributes error proportionally to the length of each side, or by least squares adjustment.
Which instrument uses electronic distance measurement (EDM) combined with an angle-measuring theodolite?
Answer: Total station
A total station integrates an electronic distance measurement device with a digital theodolite, allowing simultaneous measurement of angles and distances.
Contour lines on a topographic map that are close together indicate:
Answer: Steep terrain
Closely spaced contour lines represent steep slopes because the elevation changes rapidly over a short horizontal distance.
