Survey camp

Survey Camp is an army tradition that was discontinued in the later part of twentieth century but was reinstated in 2002 across the universities of the world with a whole new structure. It is the civil engineering training course for two weeks usually after completion four semesters of bachelor of technology that consists of 8 days working in the field and 6 days of map preparation in the computer lab. Experts say that survey camp provides necessary foundation for civil engineers. Each day in the course there are at least 8 hours of working in the field. Students are divided into groups and they get out with practising surveyors and use their equipment out in the field. A camp incharge teacher appoints group leaders for each group; the leaders are responsible for all the works of his particular group and the equipment. In the computer lab, students learn applications such as and Carlson Survey. The students use these programs to take data collected from the field to develop topographic maps of the particular area. The basic aim of the survey camp is to know various works carried out in the industrial field by surveying, which includes determining the topography of particular area with the help of survey work, map study and reconnaissance work. The methods used for surveying are traversing, levelling and contouring

The instruments used include:

The survey practicals generally performed in Survey camp are listed below:

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×${\displaystyle \cos \theta \!}$ and Departure= L×${\displaystyle \sin \theta \ }$, where L is the length of the side and ${\displaystyle \theta \ }$ 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 permanent benchmark (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 and thus a topographic map of an area is prepared using AutoCAD or with the help of plane table survey.
