Measurement of the location of the plane of the point of the main methods are right-angled coordinates method polar coordinates method.

Methods for measuring the plane position of the setup point mainly include the following:

1. Triangulation: Using the geometric relationship of triangles, the location of the target point is determined by measuring the three sides of the triangle or the two sides and the angle.

2. Intersection measurement method: Using the principle that measuring lines in different directions intersect at the target point, the location of the target point is determined by measuring the position and distance of the intersection point.

3. Coordinate Measurement Method: Establish a plane right-angle coordinate system, and determine the coordinate position of the target point by measuring the horizontal and vertical distance from the target point to the origin of the coordinate system.

4. Optical measurement method: the use of optical instruments, such as latitude and longitude, automatic leveling instrument, etc., through the observation of the angle and distance between the target point and the known points, to determine the location of the target point.

5. GPS measurement method: using the Global Positioning System (GPS) technology, through the reception of satellite signals, to measure the position coordinates of the target point.

6. Remote Sensing: Using satellite remote sensing or airborne remote sensing technology to determine the location of the target point by acquiring ground image data, interpreting and analyzing it.

Right-angle coordinate method refers to the coordinate system labeled with the method of projecting the distance from a point in the plane in the longitudinal and transverse directions, and the values represented by the coordinates are the distances of the line segments projected on the longitudinal and transversal axes, respectively, from the origin, and then the quadrant according to the quadrant added positive and negative signs to indicate.
