Full course description

This course provides a detailed overview of datums, which are reference systems used for computing or correlating survey results. It covers the two main types of datums: vertical and horizontal. You'll learn that a vertical datum is a level surface to which heights are referred, and how geodetic leveling, a precise technique for determining elevation differences between control points, is conducted. The course emphasizes the importance of following general procedures, understanding sources of errors, maintaining equipment, performing collimation and compensation checks, and adhering to observing routines. This knowledge is crucial for accurately leveling a line within the National Geodetic Vertical Control Network.
