The document discusses a Total Station, which is a surveying equipment that combines an EDM instrument, electronic theodolite, microprocessor, electronic data collector and storage system. It is used to measure horizontal and vertical angles and sloping distances of a target to the instrument. A Total Station can accurately measure distances, average multiple observations, compute horizontal distances, and display horizontal and vertical distances and angles as well as difference in elevations and coordinates of observed points. It can store observations electronically and upload and download data.
