What are Latitude and Longitude?


It is the angular distance of any point from the equator, measured north or south, along with the earth’s curved surface equaling the angle between the respective horizontal planes. It is measured in degrees, minutes, and seconds, each minute equaling one sea-mil in length.


It is the angle between the terrestrial meridian drawn from the pole, through a place, and a standard meridian now taken at Greenwich. All determination of longitude is based on the earth turning through 360 in 24 hours, or the sun reaching 15 west each hour.
