- Linen Tape.
- Woven Metallic Tape.
- Steel Tape.

Which tape is used for accurate survey work?
3. Steel tape: – Steel tapes vary in quality and accuracy of graduation, but even a poor steel tape is generally superior to a cloth or metallic tape for most of the linear measurements that are made in surveying. A steel tape consists of a light strip of width 6 to 10 mm and is more accurately graduated.
