Surveying distance tool, 50m and 100m, has been used largely Linen tape covering with bronze line of a kind of rope instead of a sort of tape till now, but recently it was fortunate to appear chemical fiber tape which had improved a defect of rope.
In this theses, each three sample of linen tape covering with bronze line and chemical fiber tape had been made capacity test and it was known what eliminate the error that come out elongation by its tension and sagging by its self-load, and finally it was found that Travers Survey without use of steel tape is taken advantage of the method to increases the precision in fild work.
