Lecture 3: The Evolution and Regionalization of
Landscape II
Examples and Uses
Evolution and Regionalization of Landscapes
Flooding
Afforestation
Deforestation
The Treatment of Spatial Data
o Pay attention to “spatial”
o Spatial: where, boundaries, here, there
Flooding
Interpretation of images reveals the production of landscape and helps flood
preparedness. These images can help governments zone the landscape and
can help insurance companies determine how much they will have to pay
out.
Landforms- Africa
Satellite Imagery:
Landforms in Sahara
Line revealing splicing of imagery, path of satellite
Political
Physical and human geography influence each other
Geosynchronous Orbit: for a fixed location on Earth the satellite returns to
exactly the same time each day
Radar sees land forms.
Water courses
Possibility of drought or flooding
Predictive ability is important for maps and geographical tools.
Fundamental Concepts
Process: how things change
Pattern: what the change is
Map projection
Spatial Diffusion
The Domain of Development
The Core
Regions of the world-system are those that dominate:
o Trade
o Control the most advanced technologies
o And have high levels of productivity within diversified
economies
The Periphery
Constitutive regions which are characterized by:
o Dependent and disadvantageous trading relationships
o By older or obsolescent technologies
o And by undeveloped or narrowly specialized economies with
low levels of productivity
The Semi-Periphery
Are able to exploit peripheral regions
But are themselves exploited and dominated by the core regions
Tri-Polar Core
North America, Japan, Europe
