Map Projections and Global Geography
Overview of Maps and Projections
Types of Maps: Thematic maps focus on specific attributes; reference maps display places of interest.
Map Projections:
- Mercator Projection: Cylindrical projection; accurate direction, distorts size and shape at poles.
- Gall-Peters Projection: Equal-area projection; maintains relative size, distorts shape.
- Azimuthal (Polar) Projections: Best for polar regions; preserves direction and distance from central point.
Data Collection and Census Information
Geospatial Technologies: Include GIS, satellite navigation, remote sensing.
Census Definition: Official population count in the U.S. every 10 years, includes all residents irrespective of citizenship.
Census Importance: Influences government funding, redistricting, and representation.
Scales of Analysis
Types of Scales: Global, regional, national, local.
Relevance of Scale: Different scales present various data interpretations and analyses.
Understanding Regions
Types of Regions: Formal (areas defined by one or more unifying characteristics), Functional (based on activities), and Vernacular (perceptual).
Regional Boundaries: Often contested, transitional, and overlapping.
Environmental Theories
Environmental Determinism: Physical environments dictate human culture and development. Humans are passive recipients of their environments.
Possibilism: Environment provides opportunities; human choices and technology shape cultural development.
Global Economy According to Wallerstein
Globalization: Interconnectedness of economies and cultures; driven by capitalistic motives.
Core, Semi-peripheral, and Peripheral Nations: Classification based on industrialization and economic roles in the global economy.
