Ideally, a third person uses a spotting scope to keep track of the group . The circles were read with a vernier scale. Such instruments are "intelligent" theodolites called self-registering tacheometers or colloquially "total stations", and perform all the necessary angular and distance calculations, and the results or raw data can be downloaded to external processors, such as ruggedized laptops, PDAs or programmable calculators[23]. It is largely set on Theodolite Island, adjacent to The Wheel, the worlds highest mountain, which soars out of the sea south of Tasmania. It should be in such a position that the theodolite is completely levelled. Most noteworthy, this result is quite a few errors in reading.

A gyrotheodolite cannot be used at the poles where the Earth's axis is precisely perpendicular to the horizontal axis of the spinner, indeed it is not normally used within about 15 degrees of the pole where the angle between the earth's rotation and the direction of gravity is too small for it to work reliably. When available, astronomical star sights are able to give the meridian bearing to better than one hundred times the accuracy of the gyrotheodolite. This method was extensively used in World War II and thereafter, and was gradually replaced by radio and GPS measuring systems from the 1980s onward. { Welcome to Tourism Australia. 8.99.
