**6. Measuring Angles The Nature of Geographic Information**

The graduated circles, one vertical and one horizontal, allow the user to actually survey for angles. How to Use a Theodolite. Mark the point at which the theodolite will be set up with a surveyorâ€™s nail or a stake. This point is the basis for measuring angles and distances. Set up the tripod. Make sure the height of the tripod allows the instrument (the theodolite) to be eye-level. The... 1 Theodolite COMPONENTS OF A THEODOLITE INTRODUCTION â€¢ The theodolite is used to measure horizontal and vertical angles. The accuracy with which these angles â€¦

Lab 3: Measurement of Horizontal and Vertical Angle Using the provided transit or theodolite set up the instrument over a point (assigned by the instructor). Choose four other different points around 3600 sweep. Use one of the chosen points as starting point (as a reference). 4. Measure and record the clockwise horizontal angles between the reference point and the other three chosen points... Chances are, the surveyors are using a theodolite or transit to measure angles. By using the principles of trigonometry, the surveyors can use measured angles to figure out exactly where they are and where they (or the construction they are responsible for) are going.

This document outlines the procedure for using the theodolite to measure angles. 1 Setup 1.1 ripTod setup In this section we learn how to set up the tripod and roughly center and level it over a small positioning mark, such as a divot in a penny glued to the oor, a nail head, or any other small xed object. (a) Place the tripod over the positioning mark, setting the legs at a convenient height

measuring angles in the horizontal and vertical planes. Uses of Theodolite Use of theodolite; It is used to measure the angle between the line of sight (collimation axis) of the telescope and the vertical axis. Vertical Clamp and Tangent Screw : This allow free transiting of the telescope. When clamped, the telescope can be slowly transited using vertical tangent screw. Main Components The... 28/09/2007Â Â· First, set up the theodolite (btw, I made one with a piece of copper tube, a protractor and a cheap wooden tripod) as noted above, make sure the ground is pretty level between the house and the theodolite, and then measure the distance from the vertical side of the house to the theodolite. (You may choose to move the theodolite so that the distance is the square of a whole number.) Then aim

### Theodolite is an instrument to measure horizontal and/or vertical angles. Meridian depicted on horizontal measurement The angle Î± is measured from a reference line , which is considered to be 0 Â°.

- The theodolite is an instrument for measuring horizontal and vertical angles. It has long had the same general look. A sighting telescope rotates on a vertical axis. A circular scale rotates on this same axis to measure the horizontal angle. A second axis, the trunnion axis, moves with the instrument and is perpendicular to the vertical axis. The trunnion axis allows the scope to pivot up and
- It is used in surveying and building to transfer, measure, or set horizontal levels. For more accurate work the "dumpy level" is very useful. It consists of a telescope mounted on a tripod stand, and can be moved about in all directions.
- This paper shows how the angular uncertainties can be determined for a rotary-laser automatic theodolite of the type used in (indoor-GPS) iGPS networks.
- A Theodolite (Survey Transit) is a survey instruments designed to precisely measure horizontal and vertical angles. In addition to measuring horizontal and vertical angles, Theodolites (Survey Transits) are used to establish straight lines, to establish horizontal and vertical distances using stadia, and to establish elevations when used as a level.
