1 In your own words define the word “map”.
Warm-up In your own words define the word “map”.

2 Introduction to Mapping
Chaper 2.1

3 Maps A MAP is a flat representation of a 3 dimensional object.

4 Every Map should have: Map Legend Map Scale Compass rose Title Date
The Best Map Ever! July 4th, 1776

5 Discuss with Your Neighbor
Did your “map” (the one you defined in the warm-up) have these items? Why did you think that you missed these items?

6 Reference Points a REFERENCE POINT is a fixed place on the Earth’s surface from which direction and location can be described For Earth these are usually the poles

7 Cardinal Directions The four major directions are known as CARDINAL DIRECTIONS North South East West

8 True North A compass is a tool that uses the natural magnetism of the Earth to show direction. A compass points to the Earth’s magnetic pole. True North: the direction to the geographic North Pole Magnetic declination: the difference between the magnetic north and the true north

9 Latitude Latitude lines are imaginary lines on the earth's surface. They run east and west around the globe and tell you your distance north or south of the Equator.

10 Longitude Longitude lines are imaginary lines on the earth's surface that run from pole to pole around the globe and tell you your distance east or west from the Prime Meridian.

11 Prime Meridian The meridian (line of longitude) at which the longitude is arbitrary defined to be zero. Set at an international conference in 1884 passing the line through the Royal Observatory, Greenwich, United Kingdom.

12 Latitude and Longitude
(35.63° N , 78.85°W) Coordinate format: (Latitude Direction, Longitude Direction)

13 A location’s coordinates (____° N or S, ____ ° E or W)

14 Degrees of Latitude Equator is 0o Poles are 90o
Divide by 60 into minutes or 35’ Divide minutes by 60 into seconds or 15’’

15 Degrees of Longitude Distance in degrees east or west of the prime meridian 0o – 180o W 0o – 180o E Not parallel, extend vertically from pole to pole. Distance between lines vary with location

16 30’ is half-way between degrees
Fractions of a Degree 1 degree = 60 minutes or 1 minute is 1/60th of a degree Use minutes if location is not directly on the latitude/longitude line Written Degree/minute = XX° xx’ compass direction 30’ is half-way between degrees

17 LONGITUDE AND TIME The world rotates (spins) 360° in 24 hours.
360° / 24 hours = 15° per hour The world has 24 time zones, each l5° apart. IN GENERAL, THERE IS A 1 HOUR TIME DIFFERENCE FOR EVERY 15° OF LONGITUDE

18 Application N W E S North America is in the Northern Hemisphere because it is north of the Equator. North America is in the Western Hemisphere because it is west of the Prime Meridian. TEKS: Social Studies – 6.3 (B), Posing and answering questions about geographic distributions and patterns 6.22 (A), Using social studies terminology correctly 7.22 (A), 8.31 (A)

19 Greenwich, England is the logical starting point for time zones
The world rotates west to east (counterclockwise), time zones to the east are ahead of the those time zones to the west

20 Time is forward to all places to the east WEST LESS
ANOTHER CHEESY SAYING EAST INCREASE Time is forward to all places to the east WEST LESS Time is backward to all places to the west

21 East Increase – West Less (1 hr per l5°)
If it 9 p.m. at Position D, what time is it at position C? B? If it is 1 p.m. at Position X, at which location is the time 5 p.m. ?

22 World Time Zones

23 INTERNATIONAL DATE LINE 180°
SEPARATES CALENDAR DAYS. America to Asia – gain a day Asia to America – lose a day If you took a cruise on a ship, circumventing, or traveling around the entire planet, you would experience firsthand a phenomena that would help you understand the importance of an international dateline. An explorer by the name of Ferdinand Magellan did just that in the year Magellan along with 241 men set out to travel around the entire Earth. These men kept very careful records as they traveled. Yet, when they returned, they found that their calendars were off by one day with the calendars of everyone in their home countries. What happened? How did these men loose an entire day? The day was not lost all at once. It was lost little by little, as the traveled around the Earth. If you stay in one place, a day lasts 24 hours. However, if you travel the opposite direction of the rotation of the Earth, your day will be slightly longer than 24 hours, because you are traveling ahead of the setting sun. If you travel with the rotation of the Earth, your day will be slightly shorter than 24 hours, because you are traveling into the sunset. At any one moment there are actually two days on the Earth at the same time. A new day begins at mid-night on the International Dateline. It travels around the Earth, until 48 hours later it ends back at the International dateline. If you were to travel across the International Dateline, the date would change either forward, or backward. This line actually lies in the middle of a time zone. This means that the hour on the clock would not change, as you crossed over, just the date.

24 California the sun is still visible.
Earth rotates west to east Solar time is based on the position of the sun NIGHT IS FALLING ON EARTH Look at the East Coast of the United States. The lights are already lit. California the sun is still visible.

25 This pictures shows AMERICAN CITIES at night.

26 Those light are Boston, New York, Philadelphia and Washington. Detroit
Saguenay Sept-Iles Thunder Bay Toronto St.John Ottawa It’s still daylight in California Québec Montréal Those light are Boston, New York, Philadelphia and Washington. Detroit Dallas Puerto Rico Houston Miami Mexico City Havana Port-au-Prince

27 Mapping Technology Remote Sensing is a technique for collecting information without having to be there. Examples: Satellites, Red-light cameras

28 Invented in the 1970’s by the military
Global Positioning System (GPS) Invented in the 1970’s by the military Uses radio signals sent to Earth to find exact locations Units are sold today that fit into the palm of your hand

29 Find these cities. Latitude is always given first:
