Map Consideration

1) HEMISPHERE
~ Everything north of the equator is called Northern Hemisphere, and the south is Southern Hemisphere. For the northern part, winter in is January and summer in July. But for southern area, summer is in January and winter is in July. Not forgetting, the world is further divided into Western Hemisphere and Eastern Hemisphere.

2) LATITUDE
~ Is the distance measured north and south of the equator (expressed in standard geography as degrees). The farther away from the equator your destination, the greater the variations will be between seasonal temperatures and between hours of night and day.

3) LONGITUDE
~ Is the distance east and west of an arbitrary line, caked the prime meridian, which passes through the Old Royal Observatory in Greenwich, England. Represented as vertical lines on most maps, longitude lines are measured in degrees. The impact on longitude lines in selling destinations is the time zone.

4) INTERNATIONAL DATE LINE
~ Time zone figuring involves international date line, a vertical zigzagging line that bisects the Pacific Ocean. Crossing it requires a bit of complicated thinking, often expressed as 'gaining a day' or 'losing a day'. The time of day remains the same.

5) ELAPSED FLYING TIME AND THE 24 HOUR CLOCK
~ One thing people often ask about that isn't always hiven in airline timetables, how long will a flight take? First, you must understand that time in the travel business is often expressed as a 4 digit number, 7 a.m is 0700, 10 a.m is 1000, and when the time changes to afternoon, instead of 1.30 p.m, it becomes 1300 hours.
