Bearings in surveying are used to indicate what?

Bearings in surveying are used to indicate direction based on cardinal points. This system of measurement provides a way to express angles in relation to North or South, combined with an East or West component, allowing surveyors to accurately communicate and record the direction of lines on a survey plan. Bearings are essential for establishing the orientation of boundaries, routes, and various features in a given area, ensuring that all stakeholders have a clear understanding of spatial relationships. They serve as a standardized method to navigate and relate points on the Earth's surface, which is crucial for tasks such as land surveying, mapping, and engineering design.

In contrast, height above sea level pertains to elevation measurements, which are typically expressed in feet or meters rather than bearings. The distance between two points is calculated using linear measurement techniques rather than angle-based systems like bearings. Lastly, while accuracy of measurement is important in surveying, it is more related to the precision and reliability of instrumentation and methods used, rather than the concept of bearings themselves.
