AP Human Geography Unit One: Key Concepts

Introduction

• Understanding Geographic Data
• Importance of Maps for Geographers
• Analyzing and Interpreting Spatial Patterns

Spatial Patterns

• Absolute and Relative Distance
  • Absolute: measurable distance (miles, km, etc.)
  • Relative: social, cultural, or political differences
• Absolute and Relative Direction
  • Absolute: cardinal directions (N, S, E, W)
  • Relative: direction relative to another location
• Clustering or Dispersal
  • Clustered: phenomena are close together
  • Dispersed: more space between phenomena
• Elevation
  • Measured by isoline maps, relative to sea level

Map Features

• Scale
  • Represents real-world distances
  • Large Scale: zoomed in, more detail
  • Small Scale: zoomed out, less detail
• Compass Rose
  • Indicates direction (N, S, E, W, NE, SE, etc.)

Types of Maps

• Reference Maps: display specific geographic locations (e.g., road maps, topographical maps)
• Thematic Maps: display geographic information
  • Choropleth Maps: use colors to represent data
  • Dot Distribution Maps: use dots to show data points
  • Graduated Symbol Maps: symbols vary in size to show data differences
  • Isoline Maps: lines depict data changes (e.g., topographic changes)
  • Cartograms: distort size of areas to represent data

Map Projections

• Mercator Projection: true direction, distorts size
• Peters Projection: accurate size, distorts shape
• Polar Projection: true directions, edges distorted
• Robinson Projection: balances distortions

Gathering Geographic Data

• Quantitative Data: numbers-based
• Qualitative Data: descriptive
• Data Collectors
  • Individuals
  • Organizations (e.g., U.S. Census Bureau)
• Geospatial Technologies
  • GPS (Global Positioning System)
  • GIS (Geographic Information System)
  • Remote Sensing

Decision Making with Geographic Data

• Individuals: travel planning
• Businesses: location selection
• Government: policy and planning (e.g., census data)

Geographic Concepts

• Absolute and Relative Location
• Space and Place
• Flows: patterns of spatial interaction
• Distance Decay: less interaction over distance
• Time-Space Compression: reduced time/cost of travel
• Patterns: random, linear, dispersed

Human Environmental Interaction

• Use of Natural Resources
  • Renewable vs. Non-renewable
• Sustainability: resource preservation
• Land Use and Cultural Landscape: built environment reflects culture

Theoretical Frameworks

• Environmental Determinism: environment shapes culture
• Possibilism: culture shapes environment

Scales of Analysis

• Global, Regional, National, and Local Scales
• Importance of Different Scales: reveals variations in patterns

Regions

• Formal Regions: linked by common traits
• Functional Regions: organized around a node
• Perceptual Regions: based on shared beliefs and feelings
• Contested Boundaries: e.g., Kashmir region
