This type of benchmark (TBM) is established at the end of the day work. Benchmark is a permanent and temporary reference point in surveying. Digital theodolite is commonly used because the digital readouts take the place of traditional graduated circles and this creates more accurate readings. The horizontal and the vertical angles are recorded using the viewing scope found on the theodolite’s side. To determine the difference in elevation between the points. While carrying out a bathymetric survey of a survey area, the datum referenced values so obtained are utilized to compute the final depth contours of this survey area for CD.
