  2. Open Access Surveying Library - Chapter B. Differential Leveling

    Differential leveling uses the vertical distance difference between two points to transfer an elevation from one point to another. A summary of the process: A Level is setup between two points, one whose …

  3. So, to apply the differential method, we first measure the vertical distance from Point A up to the line of sight, then measure the vertical distance from Point B up to the line of sight. By comparing these two …

  4. One method for measuring elevation is to use differential leveling. Surveyors extended the control network inland using a surveying technique called leveling. A vertical position is the height of a point …

  5. Differential leveling Definition - Intro to Civil Engineering Key Term ...

    Differential leveling is a precise surveying technique used to determine the height difference between two or more points. This method is essential in civil engineering for projects that require accurate …

  6. WSDOT differential leveling survey specifications are to be used for all WSDOT-involved transportation improvement projects, including special-funded projects. These specifications apply to the use of …
