(1) A list of values derived directly from measurements (for a survey) and recorded in the book in which field records are kept, together with other pertinent information. Specifically, one of the following lists. (a) In triangulation, a list of horizontal angles or directions, or ofdifferences of elevation along a base line, or of zenith angles. The measurements may be copied directly into the abstract from the book in which the measurements were recorded, or may be changed slightly (as in the case of an abstract of directions, where a constant value is added to the measured values to make a particular direction equal to zero. ) (b) In leveling, a list of measured differences of elevation, with corresponding distances and other pertinent information.
