The 20 pages that link to Theodolite, each with the reason it gives.

• SurveyingRelated: Its precision angular readings expanded the scale and accuracy of field surveys.

• AzimuthRelated: A theodolite can measure the horizontal angle used to determine an azimuth.

• SextantCompared with: Unlike a sextant, it is designed for precise land surveying and does not depend on a visible horizon.

• Great Trigonometrical SurveyRelated: Survey teams used large theodolites to observe angles between distant stations.

• Total stationRelated: Its angular measurement system is the foundation of a total station.

• Horizontal coordinate systemRelated: Its angle readings can establish a celestial object’s azimuth and altitude.

• GimbalRelated: Its telescope pivots on mounted axes to aim accurately across a range of directions.

• AlidadeNarrower topic: The alidade is the movable sighting assembly at the heart of many theodolites.

• GradianRelated: Some theodolites provide gradian graduations for field measurements.

• Radhanath SikdarRelated: Theodolite observations supplied the angles used in the Survey’s calculations.

• Spirit levelCompared with: It measures angles over long sight lines rather than checking a nearby surface directly.

• Vernier scaleRelated: Traditional theodolites use verniers to read graduated circles precisely.

• Jacob’s staffBroader topic: It developed angle measurement into a more precise and versatile surveying practice.

• MilliradianRelated: Some theodolites express measured angles in milliradians for field calculations.

• Plane tableCompared with: Unlike a plane table, a theodolite measures angles without directly drawing the map.

• Plumb bobRelated: A plumb bob can center a theodolite over a ground station.

• AutocollimatorCompared with: A theodolite measures angles over a broad range, while an autocollimator excels at tiny deviations.

• GraphometerCompared with: It offered more complete angular measurement and gradually displaced simpler graphometers.

• Legendre's theorem on spherical trianglesRelated: Its angular observations supply the triangle angles to which the correction is applied.

• Technical geographyRelated: It represents conventional ground surveying before satellite positioning.
