Offset Tapes are used in the measurement of linear distance.

Examples of Usage:

• Measuring offsets to an object from a chain line for detail mapping, also known as chain and offset measurement.
• Determining the height of an instrument, for example a theodolite or a total station, above a ground mark.
• Measuring the dimensions of objects in a detail survey, such as the diameter of a tree trunk or the width of a path.

Factors Influencing the Use of Offset Tapes:

• Measured distances are limited to the length of the tape, usually 2 or 5 metres.
• Clear paths of travel, unimpeded by physical obstacles, are needed between the end points of the distance.
• The sliding tip of the offset tape should be in good condition to maintain good accuracy.
