Basic Civil Engineering- Surveying and Levelling

Hi,
SURVEYING IS AN ART OF DETERMINING THE RELATIVE POSITIONS OF POINTS ON,ABOVE,OR BENEATH THE SURFACE OF THE EARTH.
BY MEASURING THE DISTANCES,DIRECTION,AND ELEVATION ,THE RELATIVE POSITIONS OF POINTS CAN BE DETERMINED.
AFTER KNOWING THE RELATIVE POSITIONS OF POINTS ,THEY CAN BE REPRESENTED ON A PLAN
SURVEYING IS ESSENTIALLY A PROCESS OF DETERMINING THE RELATIVE POSITIONS OF POINTS IN A HORIZONTAL PLANE.
SURVEYING INCLUDES LEVELING ALSO.
LEVELING IS AN ART OF DETERMINING THE RELATIVE HEIGHTS OF ELEVATIONS OF DIFFERENT POINTS ON EARTH'S SURFACE SO THAT THE LEVELS OF THAT CAN BE REPRESENTED ON A PLAN.
IT IS ESSENTIALLY A PROCESS TO DETERMINE THE RELATIVE POSITIONS OF POINTS IN A VERTICAL PLANE.
THE MAIN OBJECTIVE OF SURVEYING IS TO PREPARE A PLAN OR MAP.
