FAQs on Tacheometric Surveying Video Lecture - Geomatics Engineering (Surveying) - Civil Engineering (CE)

1. What is tacheometric surveying in civil engineering?
Ans. Tacheometric surveying is a method used in civil engineering to measure distances, elevations, and angles of a terrain or construction site. It involves the use of a tacheometer, which is an instrument combining a theodolite and a stadia rod to measure horizontal and vertical angles as well as slope distances.
2. What are the advantages of tacheometric surveying?
Ans. Tacheometric surveying offers several advantages in civil engineering projects. Firstly, it allows for rapid data collection as it combines the measurement of angles and distances in a single operation. Additionally, it provides accurate measurements and reduces errors compared to traditional surveying methods. Tacheometry also enables the determination of elevations and contours, making it valuable for designing roads, highways, and drainage systems.
3. How does tacheometric surveying differ from other surveying techniques?
Ans. Tacheometric surveying differs from other surveying techniques, such as chain surveying or plane table surveying, in that it allows for faster data collection and more accurate measurements. The use of a tacheometer eliminates the need for separate instruments to measure angles and distances, reducing the chances of errors. Tacheometry also provides the ability to calculate elevations and contours, which may not be possible with other methods.
4. What are the limitations of tacheometric surveying?
Ans. While tacheometric surveying offers many advantages, it also has some limitations. One limitation is that it requires skilled personnel to operate the tacheometer correctly and interpret the measurements accurately. Moreover, tacheometry is not suitable for surveys over long distances or in areas with significant obstructions. The accuracy of tacheometric measurements may also be affected by atmospheric conditions and instrument calibration.
5. Can tacheometric surveying be used for all types of civil engineering projects?
Ans. Tacheometric surveying can be used for a wide range of civil engineering projects, including the design and construction of roads, railways, buildings, and pipelines. However, its applicability depends on the specific requirements of the project and the terrain. For complex projects or those with long distances, other surveying methods, such as GPS or aerial photogrammetry, may be more suitable. It is important to assess the project's needs and consult with a qualified surveyor to determine the most appropriate surveying technique.
