  4. 4. Perceptual Region
  5. 5. What do you consider “The Southwest” of the US?
  6. 6. Perceptual Region
  7. 7. Map Projection
  8. 8. Map projection: the way we fit Earth’s three-dimensional surface onto flat paper or a screen.
  9. 9. Mercator Projection
  10. 10. Robinson Projection
  11. 11. Goode’s Homolosine Projection
  12. 12. All maps are selective.What features are included on the map? How are they depicted? Where are they depicted?
  13. 13. Color preferences and meaningColor• Logical use of color  To show an increase in intensity• Vary with culture, life cycle and demographics – RED = warning, heat, anger, courage, power, love, military force, Communism – PINK = feminine – BLUE = masculine, water – GREEN = calm, lush vegetation – YELLOW = wealth, desert

  21. 21. Scale of Inquiry
  22. 22. Map Scales (relationship between distance on map and distance on Earth’s surface)Verbal Scale: 1 inch equals 1 mile •Simple to understand •Problem: tied to a specific map (cannot compare maps of different scalesRepresentative Fraction: 1:63,360 Can be used for any linear unit of measure, including inches, feet, miles, meters etc.Graphic (or Bar) Usually subdivided toScale: allow easy calculation of distance on the map A large-scale map depicts a small area with great detail. A small-scale map depicts a larger area with little detail.
  23. 23. Distance on Map 1 1 1Distance on Ground 250,000 100,000 24,000 Largest Scale
  24. 24. Important PointAny single map is but one of a aninfinitely large number of maps thatmight be produced for the samesituation from the same data.
  25. 25. Types of Maps
  26. 26. Thematic MapsA thematic maps depicts a single feature, for example,climate, population, landform, or land use.Types of thematic maps:Isoline connects points of equal valueChoropleth puts features into classes and then maps classes for each regionProportional size of the symbol corresponds to the magnitudesymbol of the mapped featureDot each dot represents some frequency
  27. 27. Map types
  28. 28. What kind of map is this? Isoline – connects points of equal value
  29. 29. CartogramA cartogram is a map that assigns to a named earth region an area based on some value other than land surface area.
  30. 30. Vocabulary• Cognitive Map• Perceptual Region• Mercetor Projection• Robinson Projection• Goode’s Homolosine• Orientation• Scale of Inquiry• Isoline Map• Choropleth Map• Proportional Symbol Map• Dot Map
