What is vernier theodolite?
In Vernier Theodolites, vernier are used for taking the readings. These theodolites are most commonly used in the general works. Most of the general Theodolites can read upto 20"
What are theodolites used to measure?
They are surveying instruments used to measure angles.
What is the difference between transit and non transit thiodolite?
Transit theodolites (or just 'Transits') are those in which the telescope can rotate in a complete circle in the vertical plane, whereas the rotation in the same plane is restricted to a semi-circle for non-transit theodolites
What has the author Frederick Marshall Johnston written?
Frederick Marshall Johnston has written: 'Knights and theodolites'
How did the government measure mount Everest in 1852?
During Great Trigonometric Survey they used theodolites to measure Mount Everest.
What are the permanent adjustments of a theodolite?
Most theodolites have no "permanent" adjustments, since they are used to measure angles, both horizontal and vertical.
How were theodolites useful in old times?
In surveying they were used to measure horizontal and vertical angles. They were basically a small telescope mounted on a tripod
What did Sir Robert Falcon Scott use to navigate?
Navigation technologies in the age of Heroic Exploration included sextants, theodolites and other celestial navigation tools.
Who would use a Theodolite and Chain in there work?
Surveyors and engineers. Please see the related link that talks about theodolites, who uses them, how they work, and a few neat pictures:
Who was the last man to hold a theodolite?
Question is irrelevant, theodolites- including modern electronic models- are very much in use and are updated- not something obsolete like, say Steam Locomotives.
What is the size of theodolite?
Theodolites generally can weight anything from about 1 kg up to over 10 kg depending on the age and model of the theodolites. The older smaller mechanical/optical versions are generally lighter than the larger electical versions that have come out since the 1970's. Don't forget the ancillary items (e.g. protective carrying cases, tripods, batteries and recording devices). A good site to visit is: http://www.wild-heerbrugg.com/technical_data_wild_theodolite.htm
What is the difference between a transit and a theodolite?
They are the same - they are precision instruments having telescopic sights for establishing horizontal and sometimes vertical angles . In the US and Canada they are called Transit Levels, in the UK Theodolites.
