Theodolites are highly precise instruments that are used to measure angles in both the horizontal and the vertical plane. Theodolites have been around in some form since the 1500s and are used in many fields, including surveying, meteorology and aerospace engineering.
The first pictures of crude versions of the theodolite appeared in the early 16th century, although the word itself does not appear in text until 1571 in a book written by prominent English mathematician, Leonard Digges. While he uses the actual word theodolite, the sketches in the book are not as similar to those of Joshua Habermel, a German who probably truly created the first substantial theodolite around 1575. His instruments include a compass and also a tripod, where are essential for precise readings.
In the work of surveying, transit theodolites are used to plot lines of boundary, and this can be helpful in construction as well as in determining property lines. Theodolites also have been essential tools in the creation of maps, particularly in the past. They also are used to help utility workers route lines and were even used in the creation of the Transcontinental Railroad.
Another type of theodolite is the gyrotheodolite, which is used when engineers and surveyors have no way to use astronomical star sights to determine true north. A gyrotheodolite is actually two instruments mounted together, including both a theodolite and a gyroscope, which is an instrument used for stabilization and maintaining a fixed orientation. These are instruments essential in underground construction, such the creation of tunnels and mines. For example, gyrotheolodites were essential tools in the building of the Channel Tunnel that connects Calais, France to Dover, England. While these are highly useful tools, they cannot be used within 15 degrees of either pole.
Theodolites are used for navigation, and this can mean tracking the motion of weather balloons for use in meteorology or tracking other moving objects, such as airplanes or rockets that remain at altitudes lower than 20,000 meters. Theodolites are also helpful tools utilized in rocket launch technology.
While gyrotheolodites and transit theodolites look quite a bit like the early versions of these instruments, there are modern theodolites that look quite different and produce electronic readings. They look quite different, but perform much the same task, relying, rather than on the human eye, on the technology to read the measurements. While these are highly efficient and often can take readings and save the data, they are far more costly than standard theodolites.
