Definition

In SURVEYING, a short line perpendicular to a surveyed line, measured to a line or point for which DATA are desired, thus locating the second line or point with reference to the first or surveyed line. An offset is also a jog in a SURVEY or other line, the line having approximately the same direction both before and after passing the jog. Offsets are measured from a surveyed line or lines to the edges of an irre­gular-shaped body of water, or to any irregular line which it is desired to locate.
