Introduction to Digital Theodolites
A digital theodolite is an instrument used in surveying and construction to measure horizontal and vertical angles. This device has a range of features that make it more convenient and accurate than its traditional non-digital counterpart. Digital theodolites provide a digital readout, making it easier to read the results. This article will discuss the parts, working, and features of digital theodolites.
Components of a Digital Theodolite
A digital theodolite consists of a telescope, a horizontal circle, a vertical circle, and a digital display. The telescope is used to point at the target object and measure the angles. The horizontal and vertical circles are graduated circles used to measure the angles. The digital display shows the measurements in a digital format.
How a Digital Theodolite Works
A digital theodolite works by pointing the telescope at the target object and measuring the angles using the horizontal and vertical circles. The angles are then displayed on the digital display in a digital format, making the results easier to read. The measurements can then be used to determine the relative positions of points on the earth’s surface.
Features of Digital Theodolites
Digital theodolites offer a range of features that make them more convenient and accurate than their traditional counterparts. These features include:
• Electronic Distance Measurement (EDM): This feature allows the theodolite to measure distances as well as angles.
• Automatic Target Recognition (ATR): This feature enables the theodolite to automatically detect and measure the target object.
• On-board Memory: This feature allows the theodolite to store data and measurements for later use.
Conclusion
Digital theodolites provide a range of features that make them more accurate and convenient than their traditional counterparts. These features include Electronic Distance Measurement (EDM), Automatic Target Recognition (ATR), and On-board Memory. These features make digital theodolites the preferred choice for surveying and construction projects.

Reading time: 3 minutes
A theodolite is an instrument used to determine the relative position of points on the earth’s surface by measuring the horizontal and vertical angles. Theodolites can be either digital or non-digital types. Digital theodolites are more convenient and accurate as they provide digital readouts instead of reading directly from the traditional graduated circle.

Parts of a Digital Theodolite
A digital theodolite consists of a telescope mounted on a base, as shown in Figure-1 below. A sight on the top of the telescope is used to align the target. The target is made clear by using the focusing knob on the instrument. The eyepiece of the telescope is used to find the target. An objective lens is present on the opposite side of the telescope used to sight and magnify the target as required.
The parts of a digital theodolite are mostly similar to a non-digital theodolite, except for the presence of a liquid crystal display (LCD), which shows the reading of the target in focus. The display system also has operating keys for changing the device settings.
Similar to the parts of non-digital theodolite, the leveling is performed using optical plummets or plumb bobs and the spirit or bubble level.
Working of Digital Theodolite
The theodolite is first made to stand vertically above the survey point with the help of a plumb bob or optical plummet. The device is later made in level to the horizon with the help of internal spirit levels. After completing the leveling process, the telescope is used to focus on the target and the respective horizontal and vertical angles are displayed on the screen.
A typical theodolite surveying follows the below procedure:
- Mark the station on the ground using a stake or surveyor’s needle, above which the theodolite is planned to be placed.
- Place the tripod over the station. The height of the tripod is adjusted so that the instrument stays at eye level. The centered hole of the mounting plate must be over the station point.
- Mount the theodolite over the tripod and screw it in place using the mounting knob.
- The height difference between the ground and the instrument is measured. This height is used as a reference for other stations.
- The theodolite is leveled by adjusting the tripod legs and the leveling knobs.
- A plumb bob or vertical plummet can be tied at the bottom of the theodolite to adjust the level. The plummet must stay over the station nail.
- After leveling, through the telescope, aim the crosshairs at the point to be measured. The knobs on the side of the theodolite are used to lock it to keep the target on point.
- The horizontal and vertical angles are read from the LCD screen for the target.

ATR enables the theodolite to automatically detect and measure the target object. On-board Memory allows the theodolite to store data and measurements for later use. Additionally, a typical theodolite surveying follows the procedure of setting up the device vertically, leveling it, and then focusing the telescope on the target to measure the angles.
