Chain Surveying is a type of traditional surveying that involves measuring linear distances using a chain or tape and recording the location of objects and features on the earth's surface. The process involves a surveyor walking along the ground with a chain or tape and using other instruments, such as a compass or a level, to determine the position of objects and features.
Chain Surveying is commonly used for smaller or less complex surveying tasks, such as mapping the boundaries of a small piece of land or taking measurements in a relatively flat and open area. The process is relatively simple, does not require a lot of expensive equipment, and can be done quickly and efficiently.
The steps involved in Chain Surveying include:
Establishing control points: Setting up reference points or control points that will be used to guide the survey.
Measuring linear distances: Using a chain or tape to measure linear distances between control points and other objects or features on the earth's surface.
Taking angles: Using a compass or other instrument to measure angles between control points and other objects or features on the earth's surface.
Recording measurements: Recording the measurements and observations made during the survey, including distances, angles, and the location of objects and features on the earth's surface.
Plotting the survey: Using the recorded measurements to create a map or plan of the surveyed area, including the location of objects and features and the boundaries of the area surveyed.
Chain Surveying is a relatively simple and inexpensive method of surveying, but it is not as accurate as other methods, such as Total Station Surveying or GPS Surveying. It is best used for small or less complex surveying tasks where accuracy is not critical.
