Answer 2

The latitude and longitude lines are used for pin pointing the exact location of any place onto the globe or earth map. The latitude and longitude lines jointly works as coordinates on the earth or in the map. The distance between the equator and prime meridian along with direction indicates the location of any place on globe or map. Together they also define the climate condition, geographical location, and time zone of the place. Considering the Greenwich at the mid point of the state, a global time zone has been determined e.g. Kolkata’s GMT (Greenwitch Mean Time) is +5:30 as the geographical coordination of Kolkata is 22°34′11″N, 88°22′11″E. In the geographical coordinating grid system, the latitude of Kolkata is 22°34′11″N while the longitude of Kolkata is 88°22′11″E. This can also be presented into Decimal numbers like 22.3411°N and 88.2211°E.
Any geographer can find the place of the map if he/she knows the exact geographical coordination of the place. The experts can also evaluate the climate and local time of that place.
Latitude and longitude lines are also used for navigational purpose. Using the radar, the control room operator informs the pilot to where to land the aircraft. In the same way, the ship employees can find the path using the navigational instruments.
