Question

write are the uses of longitudes and latitudes

Answer 1

The function of latitude and longitude is to accurately locate a position on the surface of the earth. Latitudes are circles around the earth that are parallel to the equator. Longitudes are circles around the earth that intersect at the north and south poles. Longitude is measured in degrees east or west with zero (or 360 - remember it’s a circle) degrees longitude positioned at the Prime Meridian in Greenwich, England. Latitude is measured in degrees north or south of the equator at zero degrees, making the poles 90 degrees from the equator. The latitude and longitude coordinates form a grid on the earth’s surface that can be used to determine the location of any point on the by the combination of the two values, as in x, y coordinates on horizontal and vertical axes. The idea is more easily understood graphically: Latitude & Longitude

A great book about the development of navigation based on latitude and longitude is: Longitude: The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time.
