Assignment for Advance Surveying [for Back Log Students]

Assignment –I

(i)                 What are the various systems of coordinates employed to locate the position of a celestial body? Explain briefly.

(ii)        Draw a neat sketch to show the latitude and longitude of a place on the surface of the Earth

(iii)       Explain the importance of astronomical triangle in field astronomy. What are different   rules of spherical triangle?       

(iv)      What is probable error? List the individual errors which contribute to the total probable error.          

(v)        Enumerate the principal of least squares. Shows how this principal is used for determination of two unknowns in linear equations.

Assignment –II

(i)                 How you determine the intervisibility of triangulation stations?

(ii)        Compare the various triangulation figures mentioning their suitability. How does triangulation differ from trilateration.

(iii)       What precautions will you like to measure the base line?

(iv)       Why curve provided? Derive a relation between the radius and degree of a curve.

(v)        State the different methods of calculating the length of a transition curve.

Assignment –III

[i]         A rectangular plot of land has sides 60.45±0.02 m and 50.84±0.03 m. What should be the area of the rectangular plot?

[ii]        While measuring horizontal angles by a theodolite at station O, the following observation were recorded are A= 28⁰1’28.2”, B= 37⁰59’12.6”, C= 66⁰ 00’44.4”. Determine the most probable  values of A,B, and C

[iii]       The following observation were made in a rating test of a current meter with rating formula V=aN+b, where N= 0.4, 1.2, 1.6, 2.2 and V= 0.6, 1.8, 2.4, 2.5. Find the constant value a &b using least square method.

[iv        While measuring horizontal angles by a theodolite at station O, the following observation were recorded are A=48⁰1’28.2”, B= 76⁰59’12.6”, C= 55⁰ 00’44.4” and its wt are 3, 4, 2.  Determine the most probable values of A, B, and C.

[v]        Using matrix method  determine the most probable of the following

A= 28⁰1’28.2”,

B= 37⁰59’12.6”

A+2B=100⁰59’12.6”

C= 66⁰ 00’44.4”

2B+C=140⁰59’12.6”
