Level (instrument)
A level is an optical instrument used to establish or verify points in the same horizontal plane in a process known as levelling, and is used in conjunction with a levelling staff to establish the relative height levels of objects or marks. It is ...
Practicals
The survey practicals generally performed in Survey camp are listed below: #Simple levelling #Fly levelling #Trigonometric levelling #To determine and draw RL's of longitudinal and cross section of road. #Measuring horizontal angles by Ordinary,Repetition
Repetition may refer to:
* Repetition (rhetorical device), repeating a word within a short space of words
*Repetition (bodybuilding), a single cycle of lifting and lowering a weight in strength training

and Reiteration methods
#Compass traversing
#Gale traverse
#Topographic map preparation
Procedure
The working rule used in survey camp is quite simple, all the groups of students are allotted different stations for survey work. For first couple of days, the students carry out traversing work to determine length of different sides of traverse and included angles between them. Coordinates of each side are also determined by formulas, Latitude= L× and Departure= L×, where L is the length of the side and is the angle which the side makes with North or South directions (the instruments used in traversing include Total Station or Theodolite with stand, Compass with stand, ranging rods and measuring tape). Then in next step RL (reduced level) of each station is determined with reference to permanentbenchmark

(the instruments used to determine reduced level include Auto Level with stand and Levelling Staff). Then RL of different points keeping specified spacing between them with reference to each station is determined. The points having same RL are joined to form contour lines
A contour line (also isoline, isopleth, or isarithm) of a function of two variables is a curve along which the function has a constant value, so that the curve joins points of equal value. It is a plane section of the three-dimensional graph ...
and thus a topographic map of an area is prepared using AutoCAD or with the help of plane table survey.
