A total station is an electronic/optical instrument used in modern surveying. The total station is an electronic theodolite (transit) integrated with an electronic distance meter (EDM) to read slope distances from the instrument to a particular point.
Total Station systems has the advantages such as high efficiency, simplicity and convenience in operation, low power consumption, small weight and sizes, an opportunity of use on a tripod, in a backpack.
