Geographic Principles and Mapping

Place Geography studies anything related to place, turning… Space into Place AbstractAbstract GeometricGeometric EmptyEmpty “Just there”“Just there” RealReal Has IdentityHas Identity SignificantSignificant “It matters”“It matters”
3
SITE (physical attributes of place) + SITUATION (relationship / relative location to other places) + SENSE OF PLACE (feelings and thoughts evoked by place) = PLACE (geographic setting with distinctive physical, social, and cultural attributes: “Identity”): It’s “where stuff happens”

5
Regions! And by categorizing a bunch of places, we create…. Regions! …but What is a Region?
6
Regions come in an endless variety of shapes, sizes, and types
14
Moral of the Story: Regions are: …in the eye of the beholder.
15
Mapping these Regions
16
Maps. Why do we care about maps?
17
MAPS = LIFE
18
Not only do maps = life. “Maps” spelled backward is…

Maps Elements of a Map The Geographic Grid: o Latitude o Longitude Map Projections Scale Types of Maps GIS (Geographic Information Systems) Mental Maps

The Geographic Grid Latitude lines (parallels) run East-West, measure N or S (90˚ N) Longitude lines (meridians) run North-South, measure E or W.

Sample Questions: 1.What is the latitude and longitude of the capital of Paraguay? 2.What is biggest city in the country that exports the most bananas? 3.What is the population of the metropolitan area around the capital of the country on the southern border of Mt. Lenin? Exercise 1: Using Your Atlas

Projections: Turning a globe into a map
41
Map Projections ALL Map Projections Distort… Distance, orDistance, or Direction, orDirection, or Shape, orShape, or A combination of the above.A combination of the above.
42
Map Projections of a Human Head
43
Mercator Projection One of the first projectionsOne of the first projections Parallel lines (better for navigation)Parallel lines (better for navigation) Distortion toward poles (Greenland), therefore Northern hemisphere appears “larger”Distortion toward poles (Greenland), therefore Northern hemisphere appears “larger” (Eurocentric?)(Eurocentric?)
44
Goode’s Homolosine Projection Non-ContiguousNon-Contiguous Equal Area ProjectionEqual Area Projection Shows true areaShows true area Less distortionLess distortion Harder to navigate withHarder to navigate with
45
Combination of Mercator and Goode’s Homolosine projections Also equal area 1974 (new) Political Controversy Focuses on “South” Peters Projection
46
Robinson Projection Good between 45°N and 45°S Focuses on equator Does not show equal area Poles appear as “lines;” not points Good “visual” (not navigational) representation
47
Scale
48
Definition #1: The size/scope of places being studied Local issues versus regional, national, or global issues Scale Definition #2: Indicates the ratio of distance and area on Earth to the distance and area on a map Examples: – 1 cm on map equals 1 km – 1 inch equals 1 mile – 1 mile equals 1 mile (?) Representations: –proportional fraction (1/100,000) –ratio (1:100,000) –bar scale –verbal statement
49
BAR SCALE RATIO
50
“Opposite” meaning of scale A scale of 1/5,000 is a large-scale map compared to a scale of 1/1,000,000. Fractions: 1/5,000 > 1/1,000,000 Large-scale map: Shows a small area Shows a small area Much detail Much detail Small-scale map: Shows a large area Less detail
51
Types of Maps Choroplethic –Uses choropleths, or existing (political) units –State map, county map, country map, etc. Isometric –Uses isolines, or data lines (such as contours) –Climate, elevation, diffusion Symbolic –Proportional representation –“pie” charts, bar graphs, etc. Cartograms –Visual proportionality Or any combination of the above
52
Choroplethic Map: Choroplethic Map: Access to Clean Water
53
Isometric map: Isometric map: Climate and Weather
54
Topographic map: (using elevation contour isolines)
55
Proportional Symbolic Map: AIDS victims
56
Symbolic Map Restaurants, Gas Stations, and Stores in an area of Fort Lauderdale N ̂
57
Cartogram: Population growth rates
58
Geographic Information Systems (GIS) Data-driven digital systems Allows merging (comparison) of data using layers of information on a map. Fastest growing area of geographic jobs Highly technical, centered in government and business
59
Mental Maps (cognitive maps): OUR geographical perceptions!
