Explain the concept of offsets in chain surveying.
In chain surveying, offsets are the lateral distances measured from a survey line to objects or sites that cannot be directly surveyed. They are employed for the accurate location of borders or objects that deviate from the primary survey line, such as homes, trees, or fences.
In order to account for offsets, the surveyor measures the distance perpendicularly from the chain line to the place of interest. This helps to create a precise and comprehensive representation of the survey area. Offsets are necessary for plotting and mapping in order to ensure that all relevant features are included in the final survey plan, allowing for precise project planning and execution for land development and construction.
