A total station is a surveying instrument that is used to measure the distance between two points, as well as the angles between those points. It is a key tool in land surveying, construction, and engineering, as it allows surveyors to accurately determine the location and orientation of points on the surface of the Earth. Total stations use a combination of electronic distance measurement (EDM) and angular measurement to accurately measure distance and angles. They can be used to survey both large and small areas, and are often used in combination with other surveying tools, such as GPS systems, to provide highly accurate and detailed survey data. Total stations are essential for creating maps, laying out construction sites, and performing a wide range of other tasks in the field of surveying.
