A survey is conducted with a view to prepare the map of an area to scale 1:1000. If a scale with a least count of 0.1 mm is used for plotting, what should be the accuracy in length measurement in the field?
The type of surveying in which curvature of earth surface is taken into consideration is
In surveying to determine the position of a point at least how many measurement are required.
Consider the following statements:
Statement 1: In surveying a large part of area is divided into smaller part. The details of there smaller parts are measured using any method of surveying .
Statement 2: This principle of surveying is known as working from whole to part.
A level surface is.
i. It is a curved surface parallel to earth surface.
ii. Every element on the level surface is perpendicular to plumb line.
iii. Every point on the level surface is equidistant from the center of earth.
A map is to be prepared showing details of all natural and artificial features of earth. Which type of survey will be carried out.
The Vernier scale in whi10 divisions of the viernier is equal to 9 divisions of the main scale is called ___________
Calculate the length of one division of the vernier scale, if least count of the combination of main and vernier scale is 0.05 mm. The least count of the main scale is 1 mm.
What is the representative fraction for a scale of 10 cm = 20 km?
Calculate the length of one division of the direct vernier scale, if least count of the combination of main and vernier scale is 0.02 mm. The least count of the main scale is 1 mm.
