Those are disturbing the line of measuring is called Obstacles. The actual length of the chain is become short or some time long. this error factor are removed by calculation after measuring the distance between then by as Total Distance = (difference in length of chain /original length of chain)* Measured Distance.

What is chain surveying?
Chain surveying, also known as linear surveying, is a basic method of land surveying used to measure and map small and relatively flat areas. It is a simple and traditional technique that involves the use of chains or tapes to measure distances and basic instruments to measure angles. Chain surveying is often used for small-scale surveys such as creating maps for agricultural fields, small plots, or subdivisions. Here's how chain surveying works: 1. Measurement of Distances: In chain surveying, distances are measured using chains (typically 66 feet or 100 feet) or steel tapes. These chains or tapes are laid out along the linear features of the land being surveyed, such as property boundaries or roads. The total distance is obtained by chaining together multiple segments. 2. Measurement of Angles: Basic angles can be measured using a compass, theodolite, or other simple instruments. These angles are used to determine the direction of the surveyed lines and to calculate the layout of the land. 3. Stations and Offsets: The surveyed area is divided into smaller segments called "stations." At each station, measurements are taken to locate nearby features or boundaries, and perpendicular lines known as "offsets" are measured to mark points of interest. 4. Plotting: The data collected during the survey is used to create a scaled drawing or map of the surveyed area. The positions of boundaries, features, and angles are plotted on the map to create an accurate representation of the land. Advantages of Chain Surveying: **Simplicity:** Chain surveying is straightforward and requires minimal equipment and training. **Accuracy:** In relatively small and flat areas, chain surveying can provide accurate measurements for basic mapping purposes. **Low Cost:** It is a cost-effective method, making it suitable for smaller projects with limited budgets. Limitations of Chain Surveying: **Limited Coverage:** Chain surveying is not suitable for large or complex areas, as it becomes challenging to maintain accuracy over extended distances or rugged terrains. **Human Errors:** The accuracy of measurements in chain surveying can be affected by human errors, such as miscounting chain links or inaccurate readings. **Lack of Precision:** Chain surveying may not provide the level of precision required for detailed engineering projects or high-precision mapping. In modern surveying, more advanced methods such as total stations, GPS, and aerial surveys have largely replaced chain surveying for larger and more complex projects. However, chain surveying remains a valuable technique for smaller-scale surveys and in situations where advanced technology is not readily available or necessary.

What is importance of reconnaissance in chain surveying?
Reconnaissance in chain surveying is important because it involves gathering information about the area to be surveyed, such as identifying boundaries, obstacles, and terrain conditions. This helps surveyors plan the surveying process effectively and determine the best surveying methods to use. By conducting reconnaissance, surveyors can anticipate challenges and adjustments needed during the actual survey to ensure accurate and precise measurements.

What is the principle of chain surveying?
Type your answer here... It is the method of land surveying in which only linear measurements are made. Chain surveying requires chain, tape and ranging rods. Chain surveying is not suitable for large areas having many details. (The term "details" means a natural or man-made features at or near the ground surface)

In land surveying how many feet are in a chain?
One chain = 66 survey feet.
In land surveying how long--in feet--is a chain?
One chain is equal to 66 survey feet.
In chain surveying field work is limited to?
In chain surveying, fieldwork is limited to taking linear measurements using a chain or tape to establish distances between survey points. This method is commonly used for measuring distances along roads, property boundaries, or other linear features. The accuracy of measurements in chain surveying depends on the precision of the equipment and the skill of the surveyor.
What is the obstacle of chain surveying?
One obstacle in chain surveying is the need for a clear line of sight between survey points, which can be challenging in areas with dense vegetation, buildings, or rough terrain. Additionally, inaccuracies can arise from errors in measurement and recording when using the chain and ranging rods.
