A theodolite / θ iː ˈ ɒ d ə l aɪ t / 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 they are also used extensively for building and infrastructure construction, and some specialized applications such as meteorology and rocket launching.


Description of a Theodolite. For accurate surveying an instrument of great precision, called a theodolite, is used. Though to the uninitiated this instrument appears extremely complicated, its manipulation is simple. The theodolite is used only for measuring angles, both vertical and horizontal, and for placing marks, or stations, in a straight ...


One-Minute Theodolite . The 1-min directional theodolite is essentially a directional type of instrument. This type of instrument can be used, however, to observe horizontal and vertical angles, as a transit does. The theodolite shown in figure 11-12 is a compact, lightweight, dustproof, optical reading instrument.


Theodolite is a multi-function viewfinder that combines a compass, two-axis inclinometer, rangefinder, GPS, map, nav calculator, and geo-overlay photo/movie camera into one indispensable app. Theodolite was one of the very first augmented reality (AR) apps when it was released in 2009, and it’s been downloaded and used by millions of customers since then.


Theodolite has many parts which needs to be adjusted every time while surveying. It is important to know about theodolite parts and their functions before using it to minimize errors during theodolite surveying. Theodolite is an instrument used in surveying to measure horizontal and vertical angles ...


PROPERTY BOUNDARY DESCRIPTION . A parcel of land may be described by metes and bounds, by giving the coordinates of the property corners with reference to the plane coordinates system, by a deed reference to a description in a previously recorded deed, or by References to block and individual property numbers appearing on a recorded map.


A theodolite is a precision instrument used for measuring angles both horizontally and vertically. Theodolites can rotate along their horizontal axis as well as their vertical axis. Theodolites have a lot in common with transits. A transit is a surveying instrument that also takes accurate angular measurements.


Theodolite, basic surveying instrument of unknown origin but going back to the 16th-century English mathematician Leonard Digges; it is used to measure horizontal and vertical angles. In its modern form it consists of a telescope mounted to swivel both horizontally and vertically. Leveling is


Theodolites are essential surveying instruments used for the measurement of horizontal and vertical angles. The latest theodolites have infrared distance measuring devices, for which regular infrared inspection is essential. Leveling systems are fitted for accurate installation of theodolites. Theodolites are similar to total stations, except that the total stations are used when the distances ...


Theodolite was one of the earliest augmented reality (AR) apps for iOS when it debuted in 2009 -- in fact Theodolite was pioneering AR technology before "AR" was even a buzzword! In the time since, Theodolite has been used by millions of consumers and professionals in their outdoor adventures and on the job.
