1. OBJECTIVES To learn about the different types of maps and their purposes. To practice identifying maps.

2. HOW ARE DIFFERENT TYPES OF MAPS DISTINGUISHED?

3. REFERENCE MAPS Reference Maps include a variety of map types that show the boundaries and names of geographic areas for which the Census Bureau tabulates statistical data.

4. POLITICAL MAPS Usually colored by country or by state Political colors make it easy to compare size, shape, and location Bold letters often make the country names stand out Symbols make it easy to tell capitals from other cities Political maps also name certain physical features, such as rivers and lakes

5. WORLD POLITICAL MAP

6. PHYSICAL MAP Has colors that make natural patterns stand out The colors on the map can stand for types of vegetation, mountain, and natural features Names of big natural features are easy to see Physical maps also include some political information, such as boundaries

7. WORLD PHYSICAL MAP

8. TOPOGRAPHIC MAP These maps generally represent a small area with a lot of detail. They show elevation with contour lines, natural and man-made features.

9. TOPOGRAPHIC MAP

10. THEMATIC MAP Thematic maps are maps that depict a theme and can often be used only for explaining that theme. Population, Fertility, Communication, Age etc…

11. COLORED THEMATIC: TIME ZONES

12. CLIMATE MAP The climate of a place is the weather it has season by season, year after year Rainfall and temperature are climate’s main ingredients Climate is affected by elevation, distance from the ocean, and latitude

13. WORLD CLIMATE MAP

14. FLOW MAP Varying thickness of arrows and lines Show direction in the amount of movement of a given value.

15. GRADUATED SYMBOL Varying symbols sizes reflect data.

16. CARTOGRAM MAP Reflects statistical data Geometry or space is distorted to demonstrate some type of data.

17. CHOROPLETH MAPS Areas are colored based on an attribute Attribute values are arranged in classes Various classification methods Attribute shown as uniform throughout area Certain attributes, like population, are best shown as normalized values (pop density)

18. CHOROPLETH MAPS

19. NEW JERSEY POPULATION Normalizing an attribute by dividing its value by the area or using the percentage of the sum makes more meaningful maps. New Jersey mapped by county  "Whole value" population  Population Density (pop/area)

20. DOT DENSITY MAPS For a given attribute of the area, a value is assigned to a dot placed within its boundaries. Number of dots within the area multiplied by the value of each dot yields the attribute value. For a town with 20,000 people and a dot value of 500, 40 dots are placed on the map.

21. DOT DENSITY – GLOUCESTER

22. LIGHTS AT NIGHT – STALLELITE
