Latitudes and Longitudes Latitudes and Longitudes are imaginary lines used to determine the location of a place on earth. The shape of the earth is  ‘Geoid’.  And the location of a place on the earth can be mentioned in terms of latitudes and longitudes. Example: The location of New Delhi is 28° N, 77° E. Latitude Latitude is the angular distance of a point on the earth’s surface, measured in degrees from the center of the earth. As the earth is slightly flattened at the poles, the linear distance of a degree of latitude at the pole is a little longer than that at the equator. For example at the equator (0°) it is 68.704 miles, at 45° it is 69.054 miles and at the poles it is 69.407 miles. The average is taken as  69 miles (111km). 1 mile =
