A breakline is associated with survey points. The breakline represents a distinct interruption in the slope of a surface. Common examples of breaklines are ridge, road, cliff, or stream. It is to help define a triangulated irregular network (TIN) by clarifying smoothness and continuity.

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 Line of Collimation in surveying?
The line of collimation in surveying is an imaginary line that extends from the objective lens of a surveying instrument to the crosshairs in the telescope. It helps ensure the instrument is properly aligned and level for accurate measurements. By keeping the line of collimation straight and horizontal, surveyors can minimize errors in their readings.

What is the difference between geodetic surveying and plane surveying?
Plain surveying means the survey in which earth surface is considered as to be flat or plain i.e. its curvature is ignored. Geodetic survey is the survey in which curvature of the earth is taken into count and then surveying is done.
What is line of sight used in survey?
In surveying, line of sight is used to establish a straight line between two points for accurate measurement and mapping. It ensures that the surveyor has a clear and unobstructed view between the instrument and the target point, allowing for precise data collection. Line of sight is crucial for maintaining accuracy and consistency in surveying measurements.

What is magnetic bearing of line in theodolite survey?
The magnetic bearing of a line in theodolite surveying is the horizontal angle measured clockwise from the magnetic north direction to the line. This bearing is used to orient the theodolite and accurately measure angles during surveying work. It is important to account for magnetic declination when converting magnetic bearings to true bearings.

What are the classes of surveying?
The main classes of surveying are geodetic surveying, topographic surveying, cadastral surveying, construction surveying, and hydrographic surveying. Geodetic surveying deals with large areas and high accuracy measurements for mapping the Earth's surface. Topographic surveying focuses on determining the natural and man-made features of a specific area. Cadastral surveying involves demarcating property boundaries. Construction surveying is done to guide the construction of infrastructure and buildings, while hydrographic surveying is used to map underwater features.
