The purpose of a surveying chain in land surveying is primarily to measure distances. This tool, often made of linked metal segments, allows surveyors to obtain accurate measurements between two points on the ground. The length of the chain, typically calibrated in feet or meters, provides a clear and direct means to quantify distances, which is fundamental in establishing property boundaries, laying out projects, or conducting land analysis.

While a surveying chain can indirectly assist in marking property boundaries or contribute to creating topographic maps through the data collected, its primary and most important functionality revolves around distance measurement. When measuring land, accuracy in distance is crucial as it affects all subsequent calculations and necessary assessments in the surveying process.

This emphasis on measuring distances distinguishes the correct answer from the other options, which either describe secondary functions or tools not primarily focused on the measurement of length.
