13. Mental Mapping
Mental maps represent what we know about the locations and the characteristics of places at a variety of scales (local to global)
From the layout of our homes to the distribution of oceans and continents on the surface of the Earth.
Knowledge and experience influence
the content of our mental maps.
Draw your mental map… from OCHS to your home. 13

14. Map Terminology
Reference Map – depict terrain, cities, political boundaries, and rivers at appropriate levels of detail.
Thematic Map – provide geographic overviews for specific themes like precipitation, birth rate, agricultural production, or dominant religion.

15. Reference Maps Physical Maps Topographic Political
show the natural features of the Earth.
do not contain man made features.
Topographic
Many maps only deal with the two- dimensional location of an object without taking into account its elevation. Topographic maps on the other hand do deal with the third dimension by using contour lines to show elevation change on the surface of the earth, (or below the surface of the ocean).
Political
- Show how humans have impacted the landscape. For example, city names, roads, country borders, etc. are all part of political maps.
Change frequently—wars are often the cause of political maps being redrawn.

16. Thematic Maps
Can represent a variety of information including things like climate, precipitation, vegetation, population, life expectancy, etc.
Generally used when you are looking at a single piece of information.
We like them because they…
Present information concisely
Show what we can’t see
Show spatial relationships

17. Specific types of maps

18. Cartogram
Type of thematic map in which geometry or space of the map is distorted in order to convey information.

19. Choropleth
Type of thematic map in which areas are shaded in proportion to a variable measurement (e.g. density)
Choropleths can also be used for comparison.

20. Choropleth

21. Topographic
A detailed representation of natural features on the ground, especially elevation (height).

22. Dot Maps Use dots to show information about a distribution.
A single dot may represent one occurrence of something (earthquake) or more than one (a dot may represent 100,000 people)

23. Graduated Circle Like dot maps, they use symbols.
The symbols have different sizes in proportion to some quality that occurs at that point.
The populations of cities are often depicted in graduated circle maps.

24. Map Skills
You’ll circulate through 5 map skills stations involving practice with various types of maps.
You’ll have 9 minutes to complete the questions at each, and then 1 minute to rotate to the next station.
Please write on your own paper. Always label which station you’re working on.

25. 3 Types of Maps
Physical map—focus on geographical features such as mountains, rivers, streams, vegetation, oceans, lakes – anything naturally found in the environment
Political map – shows boundaries of counties, states, countries, property lines, cities, roads – government established (human characteristics)
Theme Map- shows some type of topic
votes for president
