Slide 1: 0 * Latitude and Longitude
Slide 2: 0 * Latitude and Longitude ■Lines of Latitude and ongitude are imaginary lines hat encircle the Earth in ither an East- West direction r in a North-South direction ■Together they form a grid hich can be used to identify ocations on the Earth’s urface
Slide 3: 0 * Latitude and Longitude ■When using these lines to find a location the coordinates are always given latitude first and then longitude
Slide 4: 0 * Latitude
Slide 5: 0 * Latitude ■Latitude is the name for a group of imaginary lines that run parallel to the Equator ■The Equator is the 0 degree line and splits the earth into two equal halves – northern and southern hemispheres ■Each hemisphere is divided into 90 degrees, from the Equator to the Pole
Slide 6: 0 * Latitude ■When finding a point in the Northern hemisphere the latitude is given as (x) degrees N ■For a point in the Southern hemisphere the coordinates would be (x) degrees S
Slide 7: 0 * Latitude ■Lines of latitude get smaller as they get further north because the distance around the Earth decreases ■At the Poles the latitude is 90 degrees and the circular distance is 0km, each Pole being just a single point
Slide 8: 0 * Latitude ■There are several major lines of Latitude other than the Equator and the Poles ■They are the Tropic of Cancer, the Tropic of Capricorn, the Arctic Circle and the Antarctic Circle
Slide 9: 0 * Longitude
Slide 10: 0 * Longitude ■Lines of longitude run north-south around the planet ■They begin at the Prime Meridian and split the Earth into East and West hemispheres ■There are 180 degrees in each hemisphere
Slide 11: 0 * Longitude ■When locating a point in the Eastern hemisphere the longitude is given as (x) degrees E ■For a point in the Western hemisphere the longitude would be (x) degrees W
Slide 12: 0 * Longitude ■All lines of longitude are the same length ■There is only one important line of Longitude other than the Prime Meridian – the International Date Line ■This is the 180 degree line in both directions
Slide 13: 0 * ongitude to find a location ou simply follow the lines ntil they meet at the point ou are looking for Latitude and Longitude Finding Locations Finding ■To use latitude and Locations
Slide 14: 0 * given ■It will be a number between 0 and 90 degrees and will be followed by either an N or an S, depending on which hemisphere the location is in ■Longitude is always the second number and will be between 0 and 180 degrees, followed by either an E or a W Latitude and Longitude Finding Locations Finding Locations ■The latitude is always the first coordinate
Slide 15: 0 * points where the lines intersect ■To find locations between the points each degree is split into 60 smaller sections called minutes ■For example, the coordinates for Orono are 43 59N 78 36W Latitude and Longitude Finding Locations Finding located neatly at the ■Not all points are Locations
Slide 16: 0 * village is located 43 degrees and 59 minutes north of the Equator and 78 degrees and 36 minutes west of the Prime Meridian ■If you are using a GPS device there will be an additional set of numbers for each coordinate, called seconds ■Seconds subdivide the minutes into even smaller sections and provide additional accuracy Latitude and Longitude Finding Locations Finding Orono mean ■The coordinates for Locations that the
