What is the main task of measurement? These three tasks are also called the three basic tasks of measurement.

The main tasks of measurement are elevation measurement, angle measurement and distance measurement, which are also called the three basic tasks of measurement.

1, elevation measurement is to determine the elevation of ground points.

2. Angle measurement is one of the basic measurement work when determining the ground point, which is divided into horizontal angle measurement and vertical angle measurement.

3. Distance measurement refers to measuring the length of the connecting line between two points on the ground. Usually, what needs to be measured is the horizontal distance, that is, the length of the projection of the connecting line between two points on the horizontal plane.
