Lesson 1: Global Positioning

2. NAVIGATION
 The process or activity of accurately ascertaining
one's position and planning and following a route.

3. Global Position
 Where the latitude and longitude coordinates for a
place to meet is called Global Position

4. PRIME MERIDIAN & EQUATOR LINE
 A prime meridian is a meridian (a line of
longitude) in a geographic coordinate system at
which longitude is defined to be 0°.
 The equator is an imaginary line around
the middle of the Earth at an equal distance from the
North Pole and the South Pole.

7. WHAT IS LATITUDE AND LONGITUDE
 Latitude and Longitude are the units that
represent the coordinates at geographic coordinate
system. Just like every actual house has its address
(which includes the number, the name of the street,
city, etc), every single point on the surface of earth
can be specified by the latitude and longitude
coordinates.

9. WHY ARE LINES OF LATITUDE AND LONGITUDE
USEFUL?
 Line of latitude and longitude are useful because
they help us to find any place on the world map.

10. HOW CAN WE LOCATE THE EXACT GLOBAL POSITION
OF ANY PLACE ON THE WORLD MAP?
 We can locate the exact global position of any place
on the world map by finding the latitude and
longitude coordinators that place on the world map.
