[0002] In surveying and mapping projects, the benchmark is a common and important tool for field measurement and positioning. The main function of the benchmark is to serve as a reference so that surveyors can make accurate measurements and draw maps. The importance of the benchmark provides a stable reference: the benchmark must have a stable nature as a reference for measurement. By fixing the benchmark on the ground, it can be ensured that it is not disturbed by external factors such as wind and earthquake during the measurement process. This can greatly improve the accuracy and reliability of the measurement and achieve accurate measurement: the benchmark is usually engraved with scales, which can directly measure distances and heights. Surveyors can accurately measure objects or places on the ground according to the scales on the benchmark, so as to draw accurate maps and achieve relative positioning: relative positioning is required when measuring and drawing maps. The benchmark can be used as a fixed reference to measure at different measuring points, thereby establishing a coordinate system and achieving relative positioning. .
