The Prime Meridian
Let us understand what is prime meridian:
- A prime meridian is an arbitrarily picked meridian (a line of longitude) in a geographic direction framework at which longitude is characterized to be 0°.
- Together, a prime meridian and its anti-meridian (the 180th meridian in a 360°-framework) structure an extraordinary circle.
- This extraordinary circle partitions a spheroid, similar to Earth, into two halves of the globe: the Eastern Side of the Equator and the Western Side of the Equator (for an east-west notational framework).
- For Earth’s prime meridian, different shows have been utilized or pushed in various districts since the beginning of time.
- Earth’s ongoing global standard prime meridian is the IERS Reference Meridian. It is inferred, however, contrasts somewhat, from the Greenwich Meridian, the past norm.
What are Longitudes and Latitudes?
Latitude and longitude, in map-making, are a direction framework used to decide and portray the place of any put on Earth’s surface. Latitude is an estimation of an area north or south of the Equator. Interestingly, longitude is an estimation of the area east or west of the great meridian at Greenwich (a nonexistent north-south line that goes through both geographic poles and Greenwich, London, Britain, U.K.). Latitude and longitude together can portray the specific area of any put on The planet. Both Latitude and longitude are estimated in degrees (°), which might be separated into more modest units called minutes (′) and seconds (″). (Or on the other hand, they might be communicated in decimal degrees;
