Geographic Coordinates

ΓΕΩΓΡΑΦΙΚΕΣ ΣΥΝΤΕΤΑΓΜΕΝΕΣ

Οι γεωγραφικές συντεταγμένες είναι σύστημα συντεταγμένων με δύο μεγέθη από τα οποία προσδιορίζεται η θέση των διαφόρων τόπων (εκτός των πόλων) και χρησιμεύουν στον εντοπισμό πλοίων στην επιφάνεια της γης και κατά προβολή θέσης αεροσκαφών υπεράνω αυτής. Ως βάση των γεωγραφικών συντεταγμένων λαμβάνεται ο ισημερινός και ο πρώτος μεσημβρινός. Τις γεωγραφικές συντεταγμένες αποτελούν το γεωγραφικό πλάτος και το γεωγραφικό μήκος.

GEOGRAPHIC COORDINATES

Geographical coordinates are a two-dimensional coordinate system that determines the location of different locations (other than poles) and serves to locate ships on the surface of the earth and when viewing aircrafts above it. The basis of the geographical coordinates is the equator and the first meridian . The coordinates are latitude and longitude .

GEOGRAPHIC COORDINATES

Geographic coordinates are a set of numbers that define a specific location on the Earth's surface. They consist of two components: latitude and longitude.

Latitude is a measurement of a location's distance from the equator and is expressed in degrees north or south of the equator. The equator is defined as 0° latitude, and the poles are defined as 90° north and 90° south latitude.

Longitude is a measurement of a location's distance from the Prime Meridian, which is an imaginary line that runs from the North Pole to the South Pole and passes through the Royal Observatory in Greenwich, England. Longitude is expressed in degrees east or west of the Prime Meridian. The Prime Meridian is defined as 0° longitude, and the International Date Line, located approximately 180° east or west of the Prime Meridian, is where the calendar day changes.

Together, latitude and longitude form a grid system that can be used to precisely locate any point on the Earth's surface. For example, the coordinates for the Statue of Liberty in New York City are approximately 40.6892° N, 74.0445° W, which means it is located 40.6892 degrees north of the equator and 74.0445 degrees west of the Prime Meridian.

Geographic coordinates are commonly used in navigation, cartography, and geolocation services such as GPS (Global Positioning System). They are also important in fields such as environmental science, geology, and astronomy, where precise location data is necessary for research and analysis.

Longitude and latitude are actually angles measured from the earth's center to a point on the earth's surface. For example, consider the location referenced by the following coordinates:

Longitude: 60 degrees East (60° 00' 00")
Latitude: 55 degrees, 30 minutes North (55° 30' 00")

The longitude coordinate refers to the angle formed by two lines, one at the prime meridian and the other extending east along the equator. The latitude coordinate refers to the angle formed by two lines, one on the equator and the other extending north along the 60° meridian.
