AP Human Geography: Unit 1 Summary

Introduction

• The unit covers major concepts in AP Human Geography.
• Recommended resources include a study guide and the Ultimate Review Packet.
• The packet offers study materials like review videos, quizzes, and practice exams.

Map Concepts

Map Projections

• Distortion: Maps are distorted in direction, shape, area, or distance as they cannot perfectly project a 3D globe onto a 2D surface.
• Mercator Projection:
  • Conformal projection, good for direction.
  • Distorts size and location, e.g., makes Greenland appear larger than Africa.
• Goode Homolosine Projection:
  • Equal area projection, good for size and shape.
  • Distorts distances near map edges.
• Robinson Projection:
  • Minimizes distortion but spreads it across the map.
• Gall-Peters Projection:
  • Accurate for size, distorts shape and direction.

Types of Maps

• Reference Maps: Information maps showing boundaries, toponyms, and geographic features.
  • Topographic Maps: Use contour lines to show elevation changes.
• Thematic Maps: Display spatial patterns using quantitative data.
  • Choropleth Maps: Use colors/shades to display data quantities.
  • Dot Density Maps: Use dots to show data occurrences, showing clustering or dispersion.
  • Graduated Symbol Maps: Use symbols for data location and amount.
  • Isoline Maps: Connect areas with similar data, e.g., weather maps.
  • Cartogram Maps: Dynamic display of data, greatest value with largest area.
  • Flowline Maps: Show movement of goods, people, ideas.

Geographic Data

Collection Methods

• Remote Sensing: Satellite data collection, used in GIS.
• GIS (Geographic Information Systems): Analyzes and displays layered data for spatial patterns.
• GPS (Global Positioning System): Provides absolute locations.
• Field Observations: Data collected through firsthand observation.
• Personal Interviews: Gathers people's perspectives.
• Media Reports: Provide insights into region-specific occurrences.
• Government Documents & Laws: Reflect cultural values and priorities.
• Travel Narratives: Personal experiences and observations.
• Landscape & Photo Analysis: Observes changes and human impacts.

Types of Data

• Qualitative Data: Word form data, subjective, collected via observations/interviews.
• Quantitative Data: Numerical data, objective, e.g., census data.

Scale and Data Utilization

Scale of Analysis

• Local Scale: Detailed, shows data points precisely.
• National Scale: Shows spatial relationships within boundaries.
• Global Scale: Shows global patterns with less detail.

Uses of Geographic Data

• Governments: Use data for planning, law-making, and social services.
• Businesses: Use data to understand customer needs and location preferences.
• Individuals: Use data for navigation, housing decisions, and understanding global systems.

Spatial Concepts

Key Concepts

• Absolute Location: Exact, uses coordinates.
• Relative Location: Based on surrounding features.
• Sense of Place: Emotional perception of a location.
• Placelessness: Lacking a unique identity.
• Spatial Distribution: Consists of density, concentration, patterns.
• Time-Space Compression: Reduces perceived distance due to technology.
• Distance Decay: Interaction likelihood decreases with distance.

Human-Environment Interaction

• Environmental Determinism: Environment dictates societal success.
• Environmental Possibilism: Environment provides limits but does not determine success.
• Land Use: Agricultural, industrial, commercial, residential, recreational, transportational.
• Natural Resources: Renewable (e.g., crops) vs. Non-renewable (e.g., oil).
• Sustainability: Using resources without compromising future generations.

Regional Analysis

Types of Regions

• Formal Regions: Defined by common attributes (e.g., political, environmental).
• Functional Regions: Organized around a focal point (e.g., economic, transportation hubs).
• Perceptual Regions: Based on people's opinions and perceptions.
