What does an offset survey measure?

An offset survey is a method used primarily in land surveying to determine the precise measurements and layout of an irregularly shaped parcel of land. It involves taking measurements from a known reference point or line to establish the boundaries and features of the land, which often does not conform to simple geometric shapes like squares or rectangles. This method allows surveyors to accurately capture the unique contours and dimensions of the land, which is essential for tasks such as planning construction or understanding property boundaries. The focus on capturing these intricate details makes it clear that measuring the dimensions of an irregular block of land is the central purpose of an offset survey.
