How does a total station differ from a theodolite?

A total station is an advanced surveying instrument that integrates the functions of a theodolite with electronic distance measurement (EDM) capabilities. The correct choice highlights that total stations utilize laser pulses to determine distances accurately while simultaneously measuring angles, making them more versatile than traditional theodolites.

Total stations allow for the precise collection of spatial data by measuring both horizontal and vertical angles as well as distances. The incorporation of laser technology significantly enhances the measurement range and accuracy compared to purely optical methods used in conventional theodolites. This advancement in technology enables surveyors to execute tasks more efficiently and with greater precision over longer distances.

In contrast, the other choices do not accurately represent the distinctions between total stations and theodolites. For instance, total stations are fully capable of measuring both vertical and horizontal angles and do not require two operators for accuracy; typically, one operator can effectively manage a total station. Additionally, total stations are designed to operate over both short and long distances, making them suitable for a vast range of surveying applications.
