## What are coordinates used for in real life?

The latitude and longitude lines on maps of the Earth are an important example of spherical coordinates in real life. With the r-coordinate fixed at the radius of the Earth, the two-dimensional latitude and longitude plane is used to specify the location of different places on the surface of the Earth.

## How do I use GPS coordinates?

Enter coordinates to find a place

1. On your Android phone or tablet, open the Google Maps app .
2. In the search box at the top, type your coordinates. Here are examples of formats that work: Degrees, minutes, and seconds (DMS): 41°24’12.2″N 2°10’26.5″E.
3. You’ll see a pin at your coordinates.

## What are latitude and longitude coordinates used for?

A geographic coordinate system is a method for describing the position of a geographic location on the earth’s surface using spherical measures of latitude and longitude. These are measures of the angles (in degrees) from the center of the earth to a point on the earth’s surface when the earth is modeled as a sphere.

## Why do we need coordinate conversion?

The degree is equal to sixty minutes, and each minute equal to sixty seconds. Geographic coordinates often need to be converted in order to geo-register one data layer onto another. Geographic coordinates may be expressed in decimal degrees, or in degrees, minutes, and seconds.

## How important is coordinate system?

Coordinates systems are often used to specify the position of a point, but they may also be used to specify the position of more complex figures such as lines, planes, circles or spheres. For example, Plücker coordinates are used to determine the position of a line in space.

## How should coordinates be written?

Write the latitude and longitude coordinates. When writing latitude and longitude, write latitude first, followed by a comma, and then longitude. For example, the above lines of latitude and longitude would be written as “15°N, 30°E.”

## Why is the standard meridian important?

Answer. Standard meridian is useful for a country because it shows and fixes a particular time for the country. A country may have many longitudes in between and there is a time gap of 4 minutes between each longitude.

## Why do we need a standard time?

The time of a place depends on the longitude that passes through it. Since many meridians pass through it, it is important to adopt the local time of one central meridian of a country as the standard time for the country. Thus, we need a standard meridian for the country.

## What is the importance of standard time?

The main importance of standard time is that it helps in organising a uniform schedule for transport like railways and airways. It cuts down on costs that would be otherwise incurred on adjusting to different time schedules and the subsequent loss of time.
