  1. The combination of meridians of longitude and parallels of latitude establishes a framework or grid that can be used to locate exact positions on a map or globe. For example, a point made up of the coordinates 40° N 30° W is located at latitude 40° north of the Equator and longitude 30° west of the Greenwich meridian (which is expressed in decimal degrees as latitude 40 and longitude –30).

  2. The longitude is defined as an angle pointing west or east from the Greenwich Meridian, which is taken as the Prime Meridian. The longitude can be defined maximum as 180° east from the Prime Meridian and 180° west from the Prime Meridian. Both latitude and longitude are measured in degrees, which are in turn divided into minutes and seconds ...

    The length of a degree of longitude (east–west distance) depends only on the radius of a circle of latitude. For a sphere of radius a that radius at latitude φ is a cos φ , and the length of a one-degree (or ⁠ π / 180 ⁠ radian ) arc along a circle of latitude is

  4. May 24, 2024 · At the equator, the length of 1 o of latitude is equal to 110.6 km (68.7 mi.) and at the poles, the length of 1 o of latitude is equal to 111.7 km (69.4 mi.). For our purposes, we will assume the length of one degree of latitude is 111 km. Figure \(\PageIndex{4}\): Longitude (Courtesy The National Atlas)

    Latitude is given as an angle that ranges from −90° at the south pole to 90° at the north pole, with 0° at the Equator. Lines of constant latitude, or parallels, run east–west as circles parallel to the equator. Latitude and longitude are used together as a coordinate pair to specify a location on the surface of the Earth.

  8. Apr 27, 2024 · Longitude are lines that run north-south and mark the position east-west of a point. Therefore, latitude is the angular distance east or west of the Prime Meridian, which passes through Greenwich, England. Lines of longitude run from pole to pole, crossing the equator at right angles. All lines of longitude are equal in length.
