What do you mean by limiting length of' offset ' in chain surveing?

In chain surveying, limiting the length of the offset refers to restricting the distance from the main survey line to which measurements can be taken for lateral features. This is done to maintain accuracy and minimize errors caused by factors such as curvature, visibility, or ground conditions. By keeping offsets within a manageable length, surveyors can ensure that the data collected remains reliable and that the overall integrity of the survey is preserved.
