In surveying, the X axis is the vertical axis and the Y axis is the horizontal axis, while in mathematics, the X axis is the horizontal axis and the Y axis is the vertical axis.

2. The sorting directions of coordinate axes and quadrants are different.

The first quadrant is located in the upper right corner, but the plane rectangular coordinate system in surveying is arranged clockwise in the first quadrant, while the plane rectangular coordinate system in mathematics is arranged counterclockwise.

3. The origin of coordinate system has different meanings.

The origin of plane rectangular coordinate system has practical significance in surveying, but it has no practical significance in mathematics.
