_*π▪️ _*π▪️Some important points related to Surveying▪️*_
▪️The *basic principle of surveying* working from whole to part
π Prevents accumulation of errors and localised minor errors
▪️An Equilateral triangle is considered to be the best well conditional triangle
( 30° to 120° )
▪️The best shape of triangle in triangulation is isosceles with base angle 56°14'
▪️A good draftsman can plot a distance as small as a 0.25mm
▪️ Control survey for fixing the points on the boundary
▪️ land/Cadstral survey to measure the area of land ,
To Fix the legal boundaries and to locate the reference points
▪️ Astronomical survey
Study about celestial body,
Determination of latitude and longitude.
▪️ Archaeological survey
To Know The civilization of People.
πThe principle involved in chain survey is of triangulation
π Compass survey uses the principle of traversing .
πThe principle of plane table survey is parallelism .
πThe principle of Tacheometer is based on property of isosceles triangle, where ratio of the distance of the base from the apex and the length of the base is always constant .
*▪️Least Count Of Surveying Instruments*
πPrismatic Compass = 30'
π Surveyor Compass = 15'
π Total station= 1sec
πTheodolite = 20"
π levelling Staff = 5mm
π Dummy level=5mm
*▪️Important Points in surveying.*
πHorizontal plane tangential to the level surface.
πLevel surfaces parallel to the mean spheroidal surface of the earth
πRL of the line of collimation is known as the height of instrument
π Differential levelling also known as compound levelling or continuous levelling
πFly levelling is used to connect the benchmark to the starting point of alignment of any project
π Check levelling is the fly levelling done at the end of the days work to connect the point with starting point on that particular day to check the accuracy of the days work.
