    Dumpy literally means short and thick. Level Tube : Also known as Bubble Tube consists of a glass tube placed in a brass tube which is sealed with plaster of paris. Determining relative heights or depth is called levelling. The reduced level R. Reduced level RL — equating elevations of survey points with reference to a common assumed datum.

    Backsight (BS) A rod reading taken by "looking back" at a point of known elevation such as a BM or TP. Foresight (FS) A rod reading taken.This sight is considered as negative and deduced from Height of Instrument to determine RL of the point.

    The difference between their staff readings indicates a rise if back sight is more than foresight and a fall if it is less than foresight. The Rise and Fall.In order to create the benchmark scores, the survey items associated with each benchmark are first rescaled so that all items are on the same scale 0 to 1.

    If the RL of the Back staff point is known, then RL of the following staff point may be obtained by adding its rise or substracting fall from the RL of preceding point.
