You have been hired to retrace a boundary line that is 1/2 mile in length. You find the monument that marks the beginning of the line and are trying to recover the monument at the end of this line. You determine, based upon the age of the original survey (1955), that a steel tape and 1-minute transit were used. Assume that the steel tape measurement was capable of 1 in 2000 precision and the transit allowed angle observations to the nearest minute.

What is the expected maximum positional error from the 1955 data? What is the initial size and shape of the area where you would concentrate your search in order to recover the monument today?
