Simple chain survey, also known as chain and tape survey, is a basic method of surveying that uses a chain or tape measure to measure distances and angles. It has both merits and demerits, which are outlined below:

Merits of Simple Chain Survey:

  1. Simplicity: Simple chain survey is easy to understand and implement, making it accessible to individuals with limited surveying knowledge or resources. It requires minimal equipment and can be conducted by a small team or even a single person.
  2. Cost-effective: Compared to more advanced surveying techniques, simple chain survey is relatively inexpensive. It does not require expensive instruments or specialized training, making it a cost-effective option for small-scale surveys or community-based projects.
  3. Quick data collection: Simple chain survey allows for relatively fast data collection. With proper training and coordination, a team can quickly measure distances and angles on the ground, enabling the efficient mapping of large areas.
  4. Suitable for small-scale applications: Simple chain survey is well-suited for small-scale applications, such as measuring land parcels, farms, or small construction sites. It provides adequate accuracy for basic mapping purposes in these contexts.
  5. Provides basic information: Simple chain survey can provide essential information about the dimensions and boundaries of land or other features. It can be used to create basic maps, plans, or sketches that are sufficient for many practical purposes.

Demerits of Simple Chain Survey:

  1. Limited accuracy: Simple chain survey is not as accurate as more advanced surveying techniques, such as total stations or GPS. Errors can occur due to factors such as uneven terrain, inaccurate measurements, or human error. This can lead to inaccuracies in the final survey results.
  2. Lack of precision in angles: Simple chain survey relies on measuring angles using instruments like a compass or a theodolite. However, these instruments may not provide precise measurements, leading to errors in the determination of angles and subsequent mapping.
  3. Limited applicability in complex terrains: Simple chain survey is most suitable for flat or gently sloping terrains. It may not be effective in rugged or steep terrains where the use of other surveying methods, such as triangulation or aerial surveying, would be more appropriate.
  4. Limited scope for complex surveys: Simple chain survey is primarily used for measuring distances and angles. It may not be suitable for surveys that require detailed topographic mapping, contouring, or the precise location of features.
  5. Vulnerability to environmental factors: Environmental factors, such as vegetation, water bodies, or obstacles, can affect the accuracy and efficiency of simple chain survey. Thick vegetation or the presence of obstacles may hinder the measurement process or introduce errors in the survey data.

It is important for surveyors to consider the specific requirements of their survey project and assess whether simple chain survey is appropriate for the intended purpose. In some cases, it may be sufficient for basic mapping needs, while in others, more advanced surveying techniques may be necessary to achieve higher accuracy and precision.
