WebAll theodolites measure angles with some degree of imperfection. These imperfections result from the fact that no mechanical device can be manufactured with zero error. In the past very specific measuring techniques were taught and employed by surveyors to compensate for minor mechanical imperfections in theodolites. WebOptical and electronic theodolites have an identical geometric and kinematical scheme ( Figure 3.5 ). This consists of vertical and horizontal rotation axes and the collimation axis. …
Webthe complexity of the optical paths A theodolite is mounted on its tripod head by means of a forced centering plate or tribrach containing four thumbscrews, or in modern theodolites, three for rapid levelling. Before use, a theodolite must be precisely placed vertical above the point to be measured using a plumb bob, optical plummet or laser ... WebHow Does a Theodolite Work? A theodolite works by combining optical plummets (or plumb bobs), a spirit (bubble level), and graduated circles to find vertical and horizontal angles in surveying. An optical plummet …
A theodolite is a precision optical instrument for measuring angles between designated visible points in the horizontal and vertical planes. The traditional use has been for land surveying, but it is also used extensively for building and infrastructure construction, and some specialized applications … See more Preparation for making sightings Temporary adjustments are a set of operations necessary in order to make a theodolite ready for taking observations at a station. These include its setting up, centering, leveling … See more Historical background Prior to the theodolite, instruments such as the groma, geometric square and the dioptra, … See more In modern electronic theodolites, the readout of the horizontal and vertical circles is usually done with a rotary encoder. … See more • Cinetheodolite • Dumpy level • Inclinometer • LIDAR See more There is a long history of theodolite use in measuring winds aloft, by using specially-manufactured theodolites to track the horizontal and vertical angles of special weather balloons called ceiling balloons or pilot balloons (pibal).

This occurs mainly in the underground mining … See more • Media related to Theodolites at Wikimedia Commons See more WebTheodolites have an internal optical device that makes it easier to read circles with much more accuracy than other instruments. And because you don’t have to take as many repeat readings, measurements can be taken more quickly. How do I use a digital theodolite? You can use a digital theodolite by performing the following steps:
