Is there a way to make measuring in the field easier and more accurate? Yes, numerous strategies are used by surveyors to simplify their fieldwork. This column describes a few successful procedures that I have used personally or have heard of others using.
With a little research, I found that the expression "rule of thumb" has been historically recorded since the year 1692 and probably was used decades or even centuries before then. It meant then what it means now: some method or procedure that comes from practice or experience, or a rough and useful principle or method based on experience rather than precisely accurate measures.
