1. Latitude, Longitude, and GIS
“Where’s Waldo” just got a lot less fun

2. Find Waldo in the picture
Find Waldo in the picture. Write his relative location on the top of a piece of paper

3. 1A 2 3 4 5 6 7 8 9 B C D E F G

4. Hemispheres
To help geographers classify and describe places on Earth, the globe is divided into 4 hemispheres:
Northern
Southern
Western
Eastern

5. Equator: Imaginary line that divides the Northern and Southern Hemisphere
Prime Meridian: Imaginary line that divides the Eastern and Western Hemisphere
Grid system: crisscrossing lines that help find exact places on earth’s surface

6. Latitude
Lines on the grid system that circle the Earth parallel to the Equator
Described as North or South
Equator: 0°
Poles: 90 ° North/South

8. Longitude Lines on the grid system that circle
the Earth parallel to the Prime Meridian
Described as East or West
Prime Meridian: 0°
The opposite side of the Earth
from the Prime Meridian is the
International Date Line

10. Absolute Location Latitude and Longitude describe an absolute location
Tokyo, Japan’s absolute location: 36 °N 140 ° E
Relative location describes a place in relation of one location to another
Tokyo, Japan’s relative location?

11. Geographic Information Systems
Computer program that combines maps, satellite images, statistics, and other data to create a complex map with several layers of information.
Google Earth uses GIS technology to present multiple layers of information at the same time. The user chooses the information needed.

12. Physical Map
Physical Maps show the location and the shape of the Earth’s physical features
Topography= shape of the Earth’s physical features
Show rivers, lakes, mountains, valleys, etc.
Show relief: differences in elevation (height)
Using different colors
Physically by being taller (3-D maps)

16. Political Map
Political Maps show the boundaries and locations of political units like countries, states, cities, and towns and man-made things like roads
Natural features like oceans are also often on political maps
Areas that are not the focus of the map are usually a different, dull color

18. Thematic Maps
Thematic Maps: Maps that emphasize a particular kind of information about an area
Can show things like climate, vegetation, population density, and economic activities
Qualitative maps: use colors, lines, symbols, or dots to show information related to a specific idea
Flow-line maps: use arrows to show the movement of animals, goods, and ideas or processes like hurricanes or glaciers

21. Reading a Map
Title: tells you what kind of information the map is showing
Scale Bar: shows the relationship between map measurements and actual distances on the Earth.
Compass Rose: Indicates directions…which way on the map is North?
Cardinal Directions: North, South, East, and West

22. Reading a Map
Legend/Map Key: explains the symbols, colors, and lines used on the map.
Cities: represented by a dot
Capitals: represented by a star within a circle
Boundary lines: show the borders between different countries and states
