SEPTEMBER 16, 2014 Day 8 - AP Human Geography

Warm Up Day /17/14 Take a few minutes, make sure everything is squared away on you Lost at Sea activity and put all of your names on it to turn in. Reflect: What are 3 things that you learned from doing this activity? Compare your measurements from the Atlas and from timeanddate.com. What did you notice/learn from this process? What conclusions can you make?

Agenda Map Quiz – South America Drill - Time Zones Distortion Types of Maps

“GPS or a Global Positioning System determines the precise position of something on Earth through satellites, tracking stations, and receivers.”

What is remote sensing?

“Remote sensing is the acquisition of data about the Earth’s surface from a satellite orbiting the planet or from other long distance methods.”

What is a geographic model?

“A Geographic Model is a simplified way to explain complex patterns, make informed decisions and explain future behaviors.”

Map projections Project a round globe onto a flat surface Options? Stretch out some areas Cut out some areas Shrink some areas

Map projections WHEN CONSIDERING WHAT TO INCLUDE ON A MAP: Three properties to consider  Area (equal-area or equivalent)  Shape (conformal)  Distance (equidistant) How large an area? Purpose of the map Ulterior motives?

Cylindrical projections Shapes are preserved But not area! Mercator projection Deliberate distortion? –Cold War –Colonialism

Cylindrical projections: Gall- Peters Adjusting Mercator for a more “just” map Also preserves area Distorts shape differently

Conic projections Best for hemispheres or small regions Area and shape only slightly distorted

Planar projections Equidistant; good for navigation Only good for one hemisphere Distorts area, not shape

Other projections Based on more complicated math Interrupted, oval, combination Goode Robinson
