What is the arc length in relation to a curve on a plat?

The length along the curve itself accurately defines arc length in relation to a curve on a plat. In surveying and land platting, when dealing with curves, the arc length represents the true distance that one would travel if moving along the curve from one end to the other, as opposed to just measuring a straight-line distance.

This measurement is significant in land surveying since curves are commonly utilized in roads, property boundaries, and other features. Understanding arc length is essential for accurately calculating distances and ensuring compliance with surveying regulations and standards.

Other definitions, such as the distance from the center to the endpoint of the curve or the straight line distance across the curve, do not provide the actual distance one would traverse if following the curve. Additionally, the total length of all adjoining sides does not pertain to arc length specifically; it would refer to the sum of straight-line distances. Therefore, recognizing that arc length is specifically about following the curve is critical in this context.
