![]() Advertisements Arbitrary meridians are sometimes used in small-scale mapping or surveying projects that do not require global or standardized references. It is often chosen based on convenience, ease of measurement, or local requirements. Unlike the prime meridian, which is internationally recognized and established as the reference point for measuring longitudes, an arbitrary meridian can be any line of longitude that is designated for a particular project or local use. Meridians also called a line of longitude are imaginary lines that run from true north to true south poles along the earth’s surface as shown in the figure. These lines include latitudes, which extend horizontally from west to east, and longitudes or meridians, which extend vertically from the North Pole to the South Pole. In the field of geography, we utilize a system of imaginary lines to define and understand different regions on the Earth's surface. These poles are widely recognized as true north or geographical north and true south or geographical south. Advertisements What are Meridians in Surveying? We know the fact that the Earth rotates around an axis that connects the North and South Poles. This article comprises the types of meridians and bearings that are used for surveying and geographical measurements. In order to grasp the concepts of meridians, bearings, and surveying, it is essential for you to comprehend this fundamental concept. In surveying, meridians and bearings play crucial roles in determining and expressing directions between points.
