1. Three Basic Types of Maps

2. What is a map? A map is a representation, usually on a flat surface, of the features of an area of the Earth or a portion of the heavens, showing them in their respective forms, sizes, and relationships according to some convention of representation. A map is a representation, usually on a flat surface, of the features of an area of the Earth or a portion of the heavens, showing them in their respective forms, sizes, and relationships according to some convention of representation. Now what does that mean?

3. ► ► A map is a representation   A map is a drawing or model ► ► Usually on a flat surface   Of a round Earth on a flat surface ► ► The features of an area of the Earth   Shows the landforms (mountains, rivers, etc.) ► ► A portion of the heavens   Part of the sky in a particular region ► ► Showing them in their respective forms, sizes, and relationships   Drawn to scale ► ► According to some convention of representation   Using an accepted form of drawing or model

4. Three Basic Types of Maps A map is an accepted drawing or model of a round Earth drawn to scale on a flat surface. A map can show landforms such as, mountains, rivers, and deserts. Also can include parts of the sky in a particular region.

5. Physical Maps ► Physical maps show the natural features of the Earth. ► Physical maps do not contain man - made features.  For example, a physical map would be a map of what you would see if you were looking down on Earth from space.

6. When you look at this map, what do you see? Notice you do not see country borders or city markings. These divisions are created by people. For example, there is no actual line dividing Texas from its bordering states. Although some astronauts (with the use of binoculars believe it or not) are able to see roads, large ocean tankers, and even the Great Pyramids from space, at very high altitudes, none of these are visible and all you are left with are natural land formations.

7. Political Maps  Political maps show how humans have impacted the landscape.  For example, city names, roads, country borders, etc. are all part of political maps.  Political maps change frequently (physical maps change very slowly through geologic processes) and must be redrawn often. A political map of the world that is 50 years old is no longer accurate.  Wars and ethnic conflict are two major reasons why political maps change.

9. Thematic Maps ► Thematic maps can represent a variety of information including things like climate, precipitation, vegetation, elevation, population, life expectancy, etc. ► Thematic maps are generally used when you are looking at a single piece of information.

11. Creating a Thematic Map ► I decided to create a thematic map. ► I chose the topic of favorite Pizza toppings for one of my classes. ► Now I need to decide on a way to represent the information I have collected.

12. A classroom is set up in the following manner… = Student Desk

13. I need to decide what information I want to know more about. ► I wanted to know which pizza toppings students prefer to eat from the following list; Pepperoni, Hamburger, Cheese, or Sausage ► I will now ask the students to choose from this list of toppings and record the results.

14. ► Now I need to choose a way to represent the information (data) I have gathered. ► I have chosen to use different colors to represent each different pizza topping. ► By using varied colors I can get a visual idea of the distribution of pizza topping preferences.

15. For example, the thematic map of my classroom may look like this… Pepperoni HamburgerCheeseSausage

16. According to this thematic map of the classroom, which pizza topping is the most popular?

17. Creating a Thematic Map ► You are now going to create a thematic map. ► You need to find out what pizza topping is the classes favorite or least favorite between the choices of pepperoni, hamburger, cheese, and sausage. ► Draw a text feature in your composition book that will represents the students in your class today. ► Create a key/legend at the bottom to help us interpret the collected information. ► You will need to write down the information (data) to be used in your thematic map when the whole class is polled (asked what topping each student likes). ► Transfer the learned data onto your thematic map. ► Write a conclusion stating what you learned from reading the data presented on your thematic map.
