Difference Between Chain Surveying And Compass Surveying

Difference Between Chain Surveying And Compass Surveying

When it comes to land surveying techniques, two commonly used methods are chain surveying and compass surveying. While both methods serve the purpose of collecting data for surveying purposes, they differ in the instruments and parameters used.

Chain surveying primarily relies on chains and tapes for linear measurements. This technique is more suitable for small, level areas where precise measurements are required. On the other hand, compass surveying utilizes a compass for angular measurements and is better suited for larger areas with rough terrain and intricate features.

Chain surveying is known for its simplicity and ease of execution. It is also more cost-effective compared to compass surveying. On the other hand, compass surveying is a more complex technique that involves additional corrections for tape and compass. This method is generally more expensive due to the specialized equipment and expertise required.

Key Takeaways:

• Chain surveying relies on chains and tapes for linear measurements in small, level areas.
• Compass surveying uses a compass for angular measurements and is suitable for larger areas with rough terrain.
• Chain surveying is easier to perform and plot, while compass surveying is more complex and requires additional corrections.
• Chain surveying is more cost-effective, while compass surveying is generally more expensive.
• Both methods have their advantages and limitations, making them suitable for different surveying scenarios.

Advantages and Limitations of Chain Surveying

Chain surveying offers several advantages that make it a popular choice for surveying small areas. Firstly, it is a fast and efficient method, allowing for quick data collection and analysis. Secondly, it is a convenient technique, as it requires minimal equipment, including a compass, chain, and pencil.

This simplicity not only reduces the cost of the survey but also makes it easier to train personnel in using the method. Moreover, chain surveying can be performed in various weather conditions, making it a versatile option for surveyors.

However, chain surveying does have its limitations. One major drawback is its limited applicability to large areas or those with complex terrain. Chain surveying is primarily designed for small, level areas and may not provide accurate results in areas with undulating or rough terrain.

Additionally, the method lacks precision in measurements, especially when it comes to vertical or horizontal distances. Manual calculations are also required, which can be time-consuming and prone to errors.

To summarize, chain surveying offers advantages such as speed, cost-effectiveness, and convenience. However, its limitations in terms of area coverage, terrain suitability, and measurement precision should be taken into consideration when choosing the surveying method.

Advantages and Limitations of Compass Surveying

Compass surveying, despite its limitations, offers several advantages. One of the main advantages is its wide applicability, as it can be performed by individuals of all ages and skill levels.

Unlike other surveying methods, compass surveying requires minimal physical exertion, making it suitable for surveyors with varying levels of physical capability.

Another advantage of compass surveying is its versatility in measuring distances. When other methods are not suitable or available, a compass can be used to estimate distances effectively. Additionally, compass surveying is not affected by magnetic fields, allowing for accurate measurements in any location, regardless of electromagnetic interference.

However, it is important to note the limitations of compass surveying. One of the primary limitations is its lack of precision. Compared to other surveying techniques, compass surveying does not provide highly accurate measurements. Therefore, it may not be the best choice when precise measurements are required.

Another limitation is the time-consuming nature of calculations involved in compass surveying, particularly for large areas. Additionally, compass surveying is not reliable for long distances, and it can be challenging to relocate points after they have been set or moved.

In some areas, a permit may be required to carry out compass surveying activities. Despite these limitations, compass surveying remains a commonly employed method for on-site construction estimates and establishing land or boundary lines.
