  1. APHG Chapter 1 Key Issue 1

  2. Deep Thought • Globalization vs Local Identity • What are some examples of each? • What are the pros and cons of each? • Is the world today a “global village”? • Are the two mutually exclusive?

  3. Interactive Discussions • Expectations • Purpose • Contribution vs Dominance • Necessity of participation

  4. Purpose of Maps • What 2 purposes? • Reference • Communication • Origins of maps • Babylonians • Aristotle—spherical Earth • Eratosthenes—”geography” • Ptolemy—1st Geography Text • Phei Hsiu—Father of Chinese Cartography • Al-Idrisi and Ibn-Battutah—mapped the Muslim Empire • Evolution of maps

  5. A Little Perspective… • http://www.youtube.com/watch?v=cQVoSyVu9rk • http://www.youtube.com/watch?v=cuuluAq4TtU

  6. Types of Maps • Remember any? • Most common--Mercator • Mercator controversy

  7. Mercator Projection • 1569 • Used for ship navigation, constant course • Conformal • Small objects accurate, large objects distorted • Heavy distortion at poles

  8. Compromise Robinson Projection • 1963 • Not equal area • Not conformal • Compromise Projection • Stretches poles

  9. Interrupted Goode’s Homolosine • 1923 • Equal-area • Oceans interrupted • Land Masses are accurate size and shape

  10. Proportional Symbol Map • Uses symbols of different size to represent data at different locations on the map

  11. Choropleth • Shows statistical data by coloring or shading certain regions • Different colors show different concepts • Different saturation show quantitative differences

  12. Dot Distribution/Density Map • Map that uses a dot symbol to show the presence of a feature or phenomenon

  13. Sinusoidal Projection • East-West Scale is constant • Meridian lines should be the same • Equator distances are correct

  14. Cartogram • A map where some thematic variable is substituted for land area or distance

  15. Flow Lines Map • Mix of maps and flow charts • Show movement • Show direction • How much is flowing

  16. Mollweide • Accurate representation of area • Some distortion of shape • Good for small maps depicting global distribution

  17. Isoline • Iso is Greek for equal • Lines on a map describing the intersection of a surface with planes • Useful for many physical concepts such as wind, elevation, storms

  18. Why are we changing maps? • http://www.youtube.com/watch?v=n8zBC2dvERM

  19. Mercator vs GnomonicGreat Circles

  20. Scale • The larger the number, the smaller the scale • Effects of scale

  21. Scale DifferencesMaps of Washington State

  22. Washington State (1:10 million scale)

  23. Western Washington(1:1 million scale)

  24. Seattle Region(1:100,000 scale)

  25. Downtown Seattle, Washington(1:10,000 scale)

  26. GPS/GIS • GPS-Global Positioning System • GIS-Geographic Information System • Uses? • Differences?

  27. Cartograms • http://www.physicscentral.com/buzz/blog/index.cfm?postid=8485785988632534891 • http://show.mappingworlds.com/ • http://www.worldmapper.org/textindex/text_index.html
