What is geography ?
If "When?" is the realm of history,
then "Where?" is the primary
focus of geographic inquiry.
HERE ARE SOME
DEFINITIONS
FOUND IN VARIOUS
TEXTS
Geography --- deBlij
“Geography is concerned with the analysis
of the physical and human characteristics
of the Earth’s surface from a spatial
perspective”.
deBlij Human Geography, A-21.
Human Geography -- Fellmann
“The spatial analysis of human
populations, their cultures, their
activities and behaviors, and their
relationship with and impact on the
physical landscapes they occupy”.
Fellmann, Human Geography,
p 553.
Geography -- Rubenstein
“The scientific study of the location of
people and activities across Earth, and
the reasons for their distribution”.
Rubenstein Human Geography, p 2.

Human Geography: Five Themes





Location – the space that is occupied in the
universe (absolute/relative).
Place – physical and human characteristics: space
after humans.
Human/Environment Interactions – how
humans depend, modify, and adapt to their
environments.
Movement – how humans interact on earth, the
diffusion of religion or trade patterns through
connections of peoples.
Regions – an area with one or more shared
characteristics.

Three sources of map distortion



Map scale – most maps are smaller than the
reality they represent. Map scales tell us how
much smaller.
Map projection – this occurs because you must
transform the curved surface of the earth on a
flat plane.
Map type – you can display the same
information on different types of maps.
Map scale – tells us relationship between distance on
map and distance on earth’s surface

Ratio scale = ratio of map distance to earth distance.
 1:10,000 means that one inch on the map equals
10,000 inches earth’s surface; one centimeter
represents 10,000 centimeters; or one foot equals
10,000 feet.
 Recall a small fraction has a large denominator so
that 1:100,000 is a smaller scale than 1:25,000.
 A large-scale map depicts a small area with great
detail.
 A small-scale map depicts a larger area with little
detail. Distortion is especially severe here.



Refers to at what scale a process occurs –
For example, while the storm didn’t make
the national news, at the local scale it was
a major story.
Evolution of Mapmaking


Babylonians – 2300 BC earliest surviving
maps written on clay tablets.
Aristotle – 384-322 BC demonstrated earth
was spherical through maps.
Evolution of Mapmaking


Eratosthenes – 276-194 BC first person to use
the word geography. Also the first person to
correctly divide earth into 5 climatic regions.
Ptolemy – 100-170 AD Guide to Geography
Age of Exploration – by the 17th century,
most continents and oceans were accurately
displayed.

Diffusion
The process by which an idea
or innovation is transmitted
from one individual or group
to another across space Fellman

People move to a new
area and take their
culture with them –
examples include- crops,
culture, farming
techniques, building
styles

Information about an
innovation may spread
through a society –
examples include Hybrid corn, Cd’s, a
religious creed. Possibly
through mass media




Diffusion that spreads like a disease – but
not necessarily applying only to diseases!
Affects nearly uniformly all individuals and
areas outward from the source region
Examples – influenza, ideas on the world
wide web; agriculture (like hybrid seeds),
Buddhism (but not all religions), breaking
news, Domino Theory
Hierarchical Diffusion


The spread of an idea from persons or
nodes of authority or power to other
persons or places
Examples- Birkenstocks, Christianity,
styles of clothing, music
Stimulus Diffusion


A fundamental idea, though not the trait
itself, stimulates imitative behavior
Examples – creation of a unique Cherokee
written language, Beta vs. VHS, Macs,
Siberians domesticated reindeers (after
seeing domesticated cattle)

How to Lie with maps




A map is a generalization or representation of
the real world.
Cartography – the science of mapmaking.
All maps lie flat and all maps lie. They
contain distortions. You cannot represent the
three-dimensional earth on a flat surface
without distorting reality.
Any useful map is selective in what is put in
and left out. Example: road or subway map.
Is this a correct map of London?
Is this a correct map of London?

the reality they represent. Map scales tell
us how much smaller.

Dot – each dot represents some frequency
Isoline – connects points of equal value
Choropleth – puts features into classes and then maps
classes for each region
Cartogram – adjusts the size of the country
corresponds to the magnitude of the mapped feature
Proportional symbol – size of the symbol corresponds
to the magnitude of the mapped feature
Dot – each dot represents some
frequency

Derivation of the Inverse:



cosλ=p2∥p∥⇒λ=cos-1(p2∥p∥)
cosφ=dR⇒φ=cos-1(∥p∥R)

The Most Common:




Conformal (i.e., angles are preserved)
Equal Area (i.e., areas are in constant proportion)
Equidistant (i.e., distances are in constant
proportion)
An Important Mathematical Result:

A single projection can not be both conformal and
equal area

Now…You need to know the
following projections!
Mercator Projection

Distorts size
not shape
Mercator Projection





Stretches the poles from one length to the size of
the equator. The north-south scale is constant, but
east-west scale increases to twice the north-south
scale at 60 degrees N and infinitely at the poles.
Shapes are correct for all areas, and map has
correct directional relationships.
Look at the size of Greenland and Antarctica.
Map exaggerates the distance between Chicago and
Stockholm, both in northern latitudes.
Created in 1569
Equal Area Projection

Distorts shapes, not area
Equal Area Projection


Represents areas correctly, but distorts
shapes.
If South America is 8 times larger than
Greenland on the globe, it will be 8 times
bigger on the map.
Robinson Projection

Does not preserve size, area or shape
Robinson Projection




Frequently used.
Distorts both size and shape, but not too
much.
The major benefit of the Robinson
projection is that oceans are
uninterrupted. This projection is useful in
depicting patterns of global interaction.
Considered a compromise projection
Goode’s Projection


Goode’s projection interrupts the
oceans and tucks Australia and New
Zealand farther west than in reality.
Therefore, land masses appear
relatively large compared to the oceans.
Minimized distortion in the shape of the
various land masses and the size of one
land mass compared to other land
masses.


Lambert
Peter’s Projection


The Peters Projection World Map is one of the most
stimulating, and controversial, images of the world. When this
map was first introduced by historian and cartographer Dr.
Arno Peters at a Press Conference in Germany in 1974 it
generated a firestorm of debate. The first English-version of
the map was published in 1983, and it continues to have
passionate fans as well as staunch detractors.
The earth is round. The challenge of any world map is to
represent a round earth on a flat surface. There are literally
thousands of map projections. Each has certain strengths and
corresponding weaknesses. Choosing among them is an
exercise in values clarification: you have to decide what's
important to you. That is generally determined by the way you
intend to use the map. The Peters Projection is an area
accurate map.

REGION defined:
A region constitutes an area that shares
similar characteristics – de Blij
Debra Troxell, NBCT

Regions are an artificial construct that
geographers use to divide the world into
sections to be compared or studied.
http://www.eoearth.org/article/region
Formal or Uniform Region

Can be defined by physical criteria,
Governmental, or by cultural traits
Functional or Nodal Region


The product of interaction, of movement;
not necessarily homogenous, rather the
people of the region function together –
politically, socially, or economically
Will operate around a node


The surrounding area of a city
A newspaper circulation area
Functional Region


Core area – it characterizing features are
most clearly defined
Periphery – characteristics become less
prominent toward the region’s margins

Example – Space and Place
Identify what you knew about this space beforehand and how
you knew this (for example, perhaps you looked the place up
in an atlas or heard someone describe it.)
Describe the process whereby that space became a place for
you. Identify in what ways you learned how to “read” this
place. In other words, how did you learn to see this particular
location as a three-dimensional, meaningful place that is
different from what you knew of it as a space.
Do you have to live in a place to really “know” it? Must one
experience a space for it to become a place?
