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?

Interactive Discussions
• Expectations
• Purpose
• Contribution vs Dominance
• Necessity of participation
![Page 4: APHG](https://reader033.vdocuments.us/reader033/viewer/2022061509/56813ce5550346895da68d0d/html5/thumbnails/4.jpg)
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

Types of Maps
• Remember any?
• Most common--Mercator
• Mercator controversy
![Page 7: APHG](https://reader033.vdocuments.us/reader033/viewer/2022061509/56813ce5550346895da68d0d/html5/thumbnails/7.jpg)
Mercator Projection
• 1569• Used for ship
navigation, constant course
• Conformal• Small objects accurate,
large objects distorted• Heavy distortion at
poles
![Page 8: APHG](https://reader033.vdocuments.us/reader033/viewer/2022061509/56813ce5550346895da68d0d/html5/thumbnails/8.jpg)
Compromise Robinson Projection
• 1963• Not equal area• Not conformal• Compromise
Projection• Stretches poles
![Page 9: APHG](https://reader033.vdocuments.us/reader033/viewer/2022061509/56813ce5550346895da68d0d/html5/thumbnails/9.jpg)
Interrupted Goode’s Homolosine
• 1923• Equal-area• Oceans interrupted• Land Masses are
accurate size and shape
![Page 10: APHG](https://reader033.vdocuments.us/reader033/viewer/2022061509/56813ce5550346895da68d0d/html5/thumbnails/10.jpg)
Proportional Symbol Map
• Uses symbols of different size to represent data at different locations on the map
![Page 11: APHG](https://reader033.vdocuments.us/reader033/viewer/2022061509/56813ce5550346895da68d0d/html5/thumbnails/11.jpg)
Choropleth
• Shows statistical data by coloring or shading certain regions
• Different colors show different concepts
• Different saturation show quantitative differences
![Page 12: APHG](https://reader033.vdocuments.us/reader033/viewer/2022061509/56813ce5550346895da68d0d/html5/thumbnails/12.jpg)
Dot Distribution/Density Map
• Map that uses a dot symbol to show the presence of a feature or phenomenon
![Page 13: APHG](https://reader033.vdocuments.us/reader033/viewer/2022061509/56813ce5550346895da68d0d/html5/thumbnails/13.jpg)
Sinusoidal Projection
• East-West Scale is constant
• Meridian lines should be the same
• Equator distances are correct
![Page 14: APHG](https://reader033.vdocuments.us/reader033/viewer/2022061509/56813ce5550346895da68d0d/html5/thumbnails/14.jpg)
Cartogram
• A map where some thematic variable is substituted for land area or distance
![Page 15: APHG](https://reader033.vdocuments.us/reader033/viewer/2022061509/56813ce5550346895da68d0d/html5/thumbnails/15.jpg)
Flow Lines Map
• Mix of maps and flow charts
• Show movement• Show direction• How much is flowing
![Page 16: APHG](https://reader033.vdocuments.us/reader033/viewer/2022061509/56813ce5550346895da68d0d/html5/thumbnails/16.jpg)
Mollweide
• Accurate representation of area
• Some distortion of shape
• Good for small maps depicting global distribution
![Page 17: APHG](https://reader033.vdocuments.us/reader033/viewer/2022061509/56813ce5550346895da68d0d/html5/thumbnails/17.jpg)
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
![Page 18: APHG](https://reader033.vdocuments.us/reader033/viewer/2022061509/56813ce5550346895da68d0d/html5/thumbnails/18.jpg)

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