What is the function of lines of latitude and lines of longitude?
What is the function of lines of latitude and lines of longitude?
These coordinates are what the Global Position System or GPS uses to provide an accurate locational relay. Longitude and latitude lines measure the distance from the Earth’s Equator or central axis – running east to west – and the Prime Meridian in Greenwich, England – running north to south.
What is the function of lines of longitude?
The combination of meridians of longitude and parallels of latitude establishes a framework or grid by means of which exact positions can be determined in reference to the prime meridian and the Equator: a point described as 40° N, 30° W, for example, is located 40° of arc north of the Equator and 30° of arc west of …
Why is latitude and longitude important?
Lines of latitude and longitude has a very important role: The particular location of any place on the earth can only be traced precisely with the help of latitude and longitude of that place. Latitude also help us in understanding the pattern of wind circulation on the global surface.
What is the significance of the five lines of latitude?
The five major lines of latitude, more commonly referred to as the five major circles of latitude, mark specific points on a globe or map of Earth. Four of the lines run parallel to the equator and sit north or south above or below the equator.
How many miles is 5 degrees longitude?
Degrees of latitude are parallel so the distance between each degree remains almost constant but since degrees of longitude are farthest apart at the equator and converge at the poles, their distance varies greatly. Each degree of latitude is approximately 69 miles (111 kilometers) apart.
How many types of Meridian are there?
Define- true meridian, magnetic meridian, arbitrary meridian. 1. True meridian- the line on a plane passing through the geographical North Pole or geographical South Pole and any point on the surface of the earth is known as true meridian.
What are the types of Meridian?
Types of Meridian and Bearings
- Meridian. Meridian is a reference direction with respect to which the direction of lines are mentioned.
- 1 – True Meridian. It is the reference direction of north pole of earth from a given station point.
- 2 – Magnetic Meridian.
- 3 – Arbitrary Meridian.
- Bearings.
- 1) Whole Circle Bearing (W.C.B)
- 2) Reduced Bearing.
What is a meridian in surveying?
Meridians are imaginary lines of longitude on the earth that extend from the North to South Pole. A principal meridian is one which is used as a reference line to survey a large area. Greenwich is the starting point for all longitudinal measurements since longitude 0 degrees passes through it.
Why are longitudes called meridians?
Longitudes are known as meridians because in Geographical sense, meridians are great circles which are not parallel to each other but intersect each other at the North and the South Poles. All longitudes are great circles which meet at the Poles.
