What is the purpose of measuring horizontal angles in surveying?

To calculate the area of land
To determine property ownership
To assist in determining position and direction
To establish a site layout plan

The correct answer is: To assist in determining position and direction

Measuring horizontal angles in surveying is crucial for determining position and direction. This process involves assessing the angles formed at a survey point between two specified points on the ground. By calculating these angles, surveyors can establish clear lines of sight and direction to various points of interest, which is essential for establishing survey control networks and aligning structures accurately. This data helps in navigation and positioning, which are foundational aspects of both land surveying and construction projects. While measuring angles can indirectly contribute to calculating areas or establishing site layouts, the primary function directly related to measuring horizontal angles is to ascertain the direction between differing points. This directional information is vital for both fieldwork and the planning stages of surveying, ensuring that stakeholders can accurately interpret the land and its boundaries. The determination of property ownership and land area calculations may rely on the results obtained from angle measurements, but these are secondary purposes to the fundamental goal of direction and position establishment.
