Which of the following details need not be given at the beginning of a particular chain survey lines?
At what step of chain surveying surveyor should investigate various difficulties that may arise and think of their solution?
Whenever possible, a survey station must be fixed with reference to a minimum ____ number of permanent objects.
The work in running a survey line is ____________ fold.
An offset is laid out 2° from its true direction on the field. If the scale of plotting is 10 m to 1 cm, find the maximum length of the offset so that the displacement of the point on the paper may not exceed 0.25 mm?
What is the lateral distance of an object or ground feature measured from a survey line?
An offset is laid out 6° from its true direction on the field. Find the resulting displacement of the plotted point on the paper in a direction parallel to the chain line? (Given the length of offset is 10 m and scale is 5 m to 1 cm)
An offset is laid out 6° from its true direction on the field. Find the resulting displacement of the plotted point on the paper in a direction perpendicular to the chain line? (Given length of offset is 10 m and scale is 5 m to 1 cm)
An offset is laid out 1° 30? from its true direction on the field. Find the degree of accuracy with which the offset should be measured so that the maximum displacement of the point on the paper from both sources may be equal?
