	Theodolite - LoveToKnow 1911
		The upper plate PP is bored centrally to receive a parallel or conical pillar which supports the lower circle of the theodolite or the arm of the level which carries the telescope.
		In the theodolite the edge of the plate rr is bevelled and divided into 360 or 400 degrees, and to half degrees, or to 20 minutes or 10 minutes, according to the size of the instrument.
		The Y theodolite differs from the transit in that the supports for the telescope are low, that the telescope rests in a cradle the trunnions of which rest on the supports, and that a segment of a circle attached to the cradle replaces FIG.

	Construction of theodolite
		Today's theodolites are usually equipped with integrated electro-optical distance measuring devices, allowing the measurement in one go of complete three-dimensional vectors -- albeit in instrument-defined polar co-ordinates -- which can then be transformed to a pre-existing co-ordinate system in the area by means of a sufficient number of control points.
		In the theodolite the edge of the piate is beveled and divided into 360 or 400 degrees, and to half degrees, or to 20 minutes or 10 minutes, according to the size of the instrument.
		A theodolite is mounted on a tripod by means of a forced centering plate or tribrach, containing three thumbscrews for rapid leveling.

		If the theodolite is to be taken from a cool environment to a warm one (especially in humid conditions) allow the theodolite to warm up inside its case where it will not be subject to condensation.
		Remove the theodolite from its case and loosen the lower clamp so that the leveling plate and leveling head can be rotated independently of the centers.
		If the theodolite is in use for a long period of time it may require re-leveling periodically due to temperature effects on the tripod and theodolite base.

	Theodolite is precise tool
		A theodolite is an alignment telescope equipped with mechanisms to measure the azimuth and elevation angles to the sub-arc- second level.
		Just as it is necessary to use filters to protect the eye when looking directly through the theodolite, it is necessary to use filters to protect the CCD camera and the its internal optics against damage by the laser beam.
		Most of theodolites are polished to a bright high-luster finish, and some compass is available in an antique brass patterns.

	Jefferson's Monticello: Theodolite
		In The Worlds of Thomas Jefferson at Monticello, Lucia Stanton, Monticello's Senior Research Historian, wrote that Jefferson "fixed the true meridian of Monticello, calculated the position of features of the Monticello landscape and surrounding mountains, and may have used it in his observation of the solar eclipse in June 1778.
		Although Jefferson used this theodolite locally, he cast his ever-inquisitive vision across the American West.
		The theodolite and other scientific instruments in the Cabinet vividly reflect Jefferson's passion for science and for its practical application.

		Theodolites of this sort, as well as others with a second pair of sight vanes affixed to the graduated circle, were soon in widespread use.
		While the telescopic theodolite was popular in England, Americans preferred the surveyorâ€™s compass and, later, the surveyorâ€™s transit, which were cheaper and more robust.
		In the transit theodolite, which originated in London in the 1840s, the telescope is transit mounted, with a vertical circle mounted at one side.

	Chapter-6
		Theodolites should be equipped with a rheostat to control the intensity of the crosshair light, and with switches to turn off the crosshair and micrometer lights between readings.
		After the theodolite has been leveled, it should be oriented about its vertical axis by rotating it until the reading of the azimuth scale is the same as that of an orientation point with respect to true north.
		Accurate orientation of the theodolite with respect to true north is an essential preliminary to the observations of azimuth and elevation of the moving balloon.

		"The Theodolite is the most perfect instrument for measuring both horizontal and vertical angles by the aid of a telescope and graduated circles.
		For the purpose of surveying, the theodolite is mostly employed to take a system of triangles upon the horizontal plane of the surface of the land, and of objects at any position in which they may be placed.
		A less sophisticated type, with a horizontal but no altitude measuring circle, is called a simple theodolite, and the earliest forms had no telescope.

		Another factor affecting the choice was that the shipyard had a theodolite measurement system and the personnel were highly skilled in its use.
		The theodolite inaccuracies used here were defined by the shipyard and were reasonable, since the theodolites were mounted on heavy movable concrete pillars.
		The stability of the theodolite system was continuously monitored by repeated comparisons with fixed points on the hall floor.

	Theodolites Introduction
		The accuracy of angle measurement is subject to a number of instrumental errors and the correct field procedures.
		A theodolite is a scientific instrument used for measuring angles (directions) in the horizontal and vertical planes.
		All theodolites have similar constructional features regardless of their age or level of technology, and all perform basically the same functions.
