[0002] Surveying and mapping literally means measuring and drawing. It refers to the process of obtaining accurate geographic information through measuring and data processing of objects in the real world, and expressing it as maps or other geographic information products. The basic principles of surveying and mapping involve two aspects: measurement and drawing, including measurement principles (such as triangulation principle, distance measurement principle, angle measurement principle and elevation measurement principle) and drawing principles (such as map projection principle, geographic coordinate system principle and map symbol principle); in order to ensure the normal operation of surveying and mapping instruments, a surveying and mapping support is usually required, usually referring to a tripod, which is a device consisting of three telescopic legs and a flat support surface. It can meet the support requirements under different surveying and mapping needs by adjusting the height and stability of the tripod.
