Offset Tape

Examples Of Usage

Offset Tape can be used for:

  • 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 Which Influence The Use Of Offset Tape

  • 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.

Survey Methods Used For

Tapes are used for the measurement of linear distance.
