The surveying may be used for Following purposes
To prepare a topographical map which show hills, valleys, rivers, forests, villages, towns, etc.
To prepare a cadastral map which shows the boundaries of fields, plots, houses and other properties.
To prepare an engineering map which shows the position of engineering works such as buildings, roads ,railways ,dams ,canals.
To prepare a contour map to know the topography of the area to find out the best possible site for roads, railways, bridges, reservoirs, canals etc.
Surveying is also used to prepare military map, geological map archaeological map etc.
For setting out work and transferring details from the map on the ground.
Various topics like how to prepare and maintain sketches, maps, reports, and assume liability for work performed; verify the accuracy of survey data, and legal descriptions of surveys in order to describe, certify, involving measurements and calculations;
Record the results of surveys; calculate heights, depths, relative positions, property lines; prepare or supervise preparation of all data, charts, plots, maps, records and documents related to surveys involves in the course syllabus. The trade is valuable and important for candidates after its successful completion.
