A theodolite is an instrument that is commonly used by surveyors and also many types of engineers. It enables measurements of angles in both vertical and horizontal planes. Meteorologists also use this kind of instrument within their profession. A telescope is generally mounted on an observation theodolite. This telescope is usually movable and enhances the measurements of angles accurately.
Transit theodolites have a telescope that is capable of moving in or along a vertical plane. However, there are those in this group that are not designed to measure vertical angles. The second group is composed telescopes that are capable of operating within semi-semicircular region. These are called non-transit theodolites.
Apart from taking both vertical and also horizontal angle measurements, the observation theodolite also plays other important roles. Some of these roles include ensuring that horizontal angles are properly set. This is of great importance in that it enables professionals in different fields to ensure that their work is highly accurate. Leveling tasks and ranging tasks also can be made far easier when one uses a theodolite.
Transit theodolites were developed in the beginning of nineteenth century by American engineers. Their introduction led to replacements of sextant, octant and also railroad compasses, as well as earlier versions of the theodolite. The modern theodolites use the principle that was used by the transit type of theodolite but these have been improved greatly to enhance accuracy. Some of improvements include replacement of engraved plates with glass plates, which are read with light-emitting diodes and this greatly improves the accuracy.
Since many years ago, it might interest one to note that theodolites have been used in measurement of wind lofts. They help in measuring vertical and also the horizontal angles of pilot balloons. These balloons are also called ceiling or pibal balloons mainly used by different types of meteorologists. It has taken about 100 years to truly perfect the measurement of wind lofts and weather balloons.
The position of a balloon is mainly tracked, once per minute after its release in front of a theodolite. After the balloon has been constructed carefully and then filled, the rate of its ascent normally is determined accurately. Basing calculations on rate of ascent, angular attitude and time, the speed of wind and the direction of the wind can be estimated with ease.
A lot of developments have been done to come up with a modern theodolite. Today's theodolites are not only extremely accurate, they also are quite easy to use. In fact, the modern theodolites include a rotary encoder which greatly enhances accuracy. CCD sensors also have been added to ensure that they can perform their role automatically. The introduction of theodolites has improved accuracy abundantly in professions such as engineering, meteorology and also in surveying.
