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.
Transit and non-transit theodolite.
A theodolite is a survey instrument. A tachometer tells you how many Revs per minute an engine is turning.
Dumpty level can be used only for vertical measurements while a theodolite functions in both horizontal and vertical measurements.
Half of the difference between the two positions is called the "index error".
A theodolite is a surveying instrument used to measure horizontal and vertical angles. It requires a separate instrument to measure distances. A total station is a surveying instrument that combines the functions of a theodolite and distance measuring device, allowing for simultaneous measurement of angles and distances.
Compass traversing uses a magnetic compass to determine directions, while theodolite traversing involves the use of a theodolite, which is a more precise instrument for measuring horizontal and vertical angles. Theodolite traversing provides more accurate results compared to compass traversing.
To check vertical deviation of tower using theodolite, measure the distance between the target and the point of burst in the plane. There must be a normal line of position along a line perpendicular to the lateral deviation.
when theodolite is fixed with analytic lens then it is called tachometer, without the analytic lens the instrument would be called as constant zero.
A theodolite is a surveying instrument used for measuring horizontal and vertical angles, typically with a rotating telescope. A total station combines the functionality of a theodolite with an electronic distance measurement (EDM) device to measure angles and distances simultaneously. Total stations are more advanced and versatile than theodolites.
a transit, a theodolite or a builders level. they are used for laying out curves, building layout lines and wall heights/plumb
Vertical and Horizontal. These are absolutely vital. some have The Horizontal ( latitude or Azimuth) scale given priority- some the Vertical or Altitude scale, but both are essential to a true theodolite- unlike a transit or level instrument no matter how powerful the telescope.
