Equipment
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.
