What is the "Basis of Bearings" in surveying?

The "Basis of Bearings" in surveying refers to the reference direction for survey angles, making it a vital concept for establishing orientation in measurements. It acts as a starting point from which angles are measured, typically defined by a specific line (such as a property line or a geographic feature) and usually expressed in terms of north or south and an angle toward the east or west. This establishes a standardized framework for surveyors to ensure consistency and accuracy when determining the location and orientation of property boundaries, easements, and other important features on maps.

The concept is essential for ensuring that different surveys can be compared and correlated, as all measurements will reference the same directional baseline. This is crucial for legal descriptions and property delineation, as any inconsistency in bearing can lead to disputes or inaccuracies in a property's layout. Understanding this principle allows surveyors to communicate effectively and avoid errors in land measurement and definition.
