What is one of the data points required for a curve on a plat?

In land surveying, particularly when dealing with curves on a plat, the radius of the curve is a fundamental data point. The radius determines the size of the curve and is crucial for calculating the direction and length of the curve to ensure accurate mapping and representation of the land. This information is necessary for creating a precise geometric representation of the surveyed area, notably in areas like road construction, property delineation, or other civil engineering projects.

The angle of intersection can be relevant in certain contexts, like when connecting two straight lines, but it does not specifically describe the curve itself. The length of the fence is a linear measurement relevant to property boundaries but does not inform the characteristics of a curve. Height above sea level is typically related to elevation and does not influence the curvature of the surveyed plat directly. Thus, the radius is the essential data point necessary for defining a curve accurately on a plat.
