Draw a line AD, and on that 1 ~ mark AB. In the case of tripods two tripods required, for measuring baseline one is a straining tripod and another is measuring tripods. The range of effective measurement increments is from 0.2PE to 2PE or 0.0648 to 0.648. I don't believe the same principle applies to non-normal distributions but I will have to check that. how measure the base line in triangulation surveying, How to measure the baseline in triangulation surveying, The measurement of baseline has an important role in the triangulation surveying, because, the accuracy of computation of sides of the triangle depends upon the accuracy of the measured.
