Longitude and latitude for dummies

The system has been in use with little change since the astronomer Ptolemy used them in his first world atlas in AD. Where φ represent the latitudes and λ represent the longitudes.

It covers the definitions of latitude longitu.

Longitude and latitude for dummies. The North Pole is 90 N and the South Pole is 90 S. The line labelled 0 longitude is called the Prime Meridian or the Greenwich Meridian and runs through London. Anything lying east of the.

Latitude and longitude both start at 0 degrees. Zero degrees latitude is the equator which is the imaginary line all the way around the middle of the globe horizontally. The latitude of the North.

Another popular format for longitude and latitude coordinates is the decimal degrees format which expresses the coordinates using positive and negative values. For reference a positive coordinate means that the coordinate is located either north or east while a negative coordinate means that the coordinate is located either south or west. A sin² Δφ2 cos φ1 cos φ2 sin² Δλ2 c 2 atan2 a 1a d R c.

Where φ represent the latitudes and λ represent the longitudes. Alternatively you can use a latitude and longitude calculator which uses an algorithm based on the formula to find the distance. The global grid consists of imaginary lines of latitude and longitude see Figure 1.

Latitude lines go across the map latitude comes from the Latin latitudo meaning breadth or the measure of the side-to-side dimension of a solid. Longitude lines run from top to bottom longitude comes from the Latin longitudo meaning length. Longitude degrees extend 180 east and 180 west from the prime meridian an imaginary line dividing the earth into an eastern and western hemisphere and meet to form the International Date Line in the Pacific Ocean at 180 longitude.

0 longitude falls in Greenwich England where a physical line showing the division between the Eastern and Western hemispheres was constructed. Kids can easily understand the meaning of latitude and longitude It is explained in an interesting way by using day-to-day examples in this animation scienc. The longitude is defined as an angle pointing west or east from the Greenwich Meridian which is taken as the Prime Meridian.

The longitude can be defined maximum as 180 east from the Prime Meridian and 180 west from the Prime Meridian. Both latitude and longitude are measured in degrees which are in turn divided into minutes and seconds. Learn about latitude longitude geography and other mapping skills in this video from the Pursuit of History.

It covers the definitions of latitude longitu. The number of latitude degrees will be larger the further away from the equator the place is located all the way up to 90 degrees latitude at the poles. Latitude locations are given as __ degrees North or __ degrees South.

Vertical mapping lines on Earth are lines of longitude known as meridians. The angle of longitude is measured at the centre of the earth along the equator from the prime or Greenwich meridian 0 ranging from 0 to 180 east and to the west. The latitude and longitude scales are printed at the edge of the nautical map with grid lines crossing them allowing positions to be measured and plotted.

How to plot places on a map using latitude and longitude or grid reference. In this video we use coordinates to find the location. The latitude longitude coordinate system uses angular measurements to describe a position on the surface of the earth.

The system has been in use with little change since the astronomer Ptolemy used them in his first world atlas in AD. Mariners and aviators have been the primary users of latitudelongitude in the past. The line of longitude is read as 2 degrees 2 10 minutes 10 265 seconds 122 east.

2 Degrees and decimal minutes DMM The space between each line of latitude or longitude representing 1 is divided into 60 minutes and each minute is further divided and expressed as decimals. An example of this format is. 41 242028 2 104418.

Latitude is the angular distance of a place north or south of the earths equator. The degree of the angle is between -90 and 90. Longitude and latitude coordinates are usually expressed in degrees and minutes.

Every location consists of a latitude and longitude which is like an unique address for each point. The measurements of latitude and longitude are usually expressed in degrees minutes or seconds. The entire distance from one parallel to another or one meridian to another is 1.
