1. AP Human Geography Day 3
(8/29)

2. Starter Draw a map showing how to get from your house to school
Then write directions of how you know to get from your house to school

4. Location Absolute – where is it exactly? Relative – what is it by?
Based off some system of measurement
Latitude and Longitude
Address like with Utah’s predictable grid system
Where something is in relation to other things
Can change over time as its surroundings changes

5. Mental Mapping
A mental map is a person's representation of an area, based on what an individual knows about that place.
(Contains personal impressions of what is in the place and where the place is located)

6. Map Scale – the relationship of a feature’s size on a map to its actual size on Earth
Three ways
Fraction/ratio
1/24,000 or 1:24,000
“small scale map” shows small amounts of detail,
“large scale” shows large amounts of detail
Written statement
1 inch equals 1 mile
Bar scale

7. Map scale examples

8. Map scale examples
Not about the size of the map, but the detail you can see in it
Small Scale: Everything is small, not very detailed
Large Scale: Zoomed in, can see much more detail
What are the benefits of each?

9. With a partner – and without outside help (atlas, internet, etc.)
Draw a map of the world
Now place and identify these countries:
Syria
South Africa
North Korea

11. Think-Pair-Share
Introduce yourself to your neighbor and then discuss these 2 questions:
How do maps influence our lives?
Do maps deceive us? How?

12. Maps

17. Map Projections All maps create distortion
Projection: Transferring locations on Earth’s surface to a map
Globe most accurate, but not practical
All maps create distortion
Shape (stretched out/flattened)
Distance (closer or farther)
Relative size (smaller/bigger)
Direction

18. Mercator Projection

19. Peters Projection

20. Robinson Projection

21. Peters Projection (Reversed) 

22. Polar Projections

23. Disadvantages (Distortions)
Map Projections
Projection
Advantages
Disadvantages (Distortions)
MERCATOR
(Navigation)
Lines of latitude and longitude meet at right angles
Directions are shown accurately
Distorts size at poles
Distance between lines of latitude and longitude appear constant
PETERS
(Spatial distributions related to area)
General size of land masses is accurate
Shapes are inaccurate, especially near the poles
ROBINSON
(General Use)
No major distortion
Oval appears more like a globe than rectangle
Area, shape, and size are all slightly distorted

24. Vox
Why All Maps Are Wrong

25. True Size of…
True Size

26. Reference Maps – tell us where things are
Physical – identifies physical features of an area
Political – outlines human created boundaries

27. Thematic Maps - Tell us how human activities are distributed
Cartogram – size of map is distorted to show something other than realistic size Choropleth – uses shading/coloring to indicate different values Dot – one dot represents a certain number of phenomena Graduated symbol – size of symbol proportionate to value of attribute Isoline – lines join all points that have the same value

28. Cartograms
Shape is distorted to show emphasize a characteristic other than physical geography

29. Choropleth
Uses shading or coloring to indicate different values

30. Dot Map
One dot represents a certain number of a phenomenon

31. Graduated Symbol Map
Size of the symbol is proportionate to value of attribute

32. Isoline Map
Lines join all points that have the same value
