Study Notes
Altimeters
- Measure altitude or elevation above sea level.
Precise Leveling
- Commonly uses Automatic Levels.
Turning Points
- Used as temporary reference points in leveling surveys.
- Help in extending leveling measurements over long distances.
Rod Levels
- Used in conjunction with a level to read elevations on a leveling rod.
- Help determine elevation differences.
Self-Leveling or Automatic Levels
- Use a compensator to automatically establish a horizontal line of sight.
- This compensator is a very sensitive pendulum or a similar device.
Level Surface
- Geoid is the reference level surface used in leveling works.
- It is the theoretical surface of the Earth that corresponds to mean sea level.
Trigonometric Leveling
- Involves observing vertical angles and either horizontal or slope distance between points.
- Used to determine elevations.
Barometric Leveling
- Uses a Barometer to observe atmospheric pressure variations.
- These variations are used to determine elevation differences.
Difference in Elevation
- The vertical distance between two points on level surfaces is known as Difference in Elevation.
Level Line
- A straight line tangent to a level surface is called a Level Line.
- It represents a line of constant elevation.
