AP Human Geography Unit One: Key Concepts

Introduction

  • Presenter: Steve Heimler
  • Focus: Simplifying the understanding of geographic data and concepts for exam preparation.

Importance of Maps

  • Geographic Data Representation
    • Maps as crucial tools for analyzing spatial patterns.
  • Spatial Patterns
    • Related to the location of features on Earth's surface.
    • Examples include mountains, highways, or demographics.
  • Absolute vs. Relative Distance
    • Absolute: Measured physically (inches, feet, miles, kilometers).
    • Relative: Cultural, social, or political differences between locations.
  • Absolute vs. Relative Direction
    • Absolute: North, south, east, west.
    • Relative: Directional relation between two locations.
  • Clustering and Dispersal
    • Clustering: Phenomena close together.
    • Dispersal: Phenomena spread out.
  • Elevation
    • Measured via isoline maps.

Map Features

  • Scale
    • Ratio or bar representation of distance on maps.
    • Large scale: Zoomed in, more detail.
    • Small scale: Zoomed out, less detail.
  • Direction
    • Indicated by a compass rose.

Types of Maps

Reference Maps

  • Show specific geographic locations (e.g., road maps, topographical maps).

Thematic Maps

  • Display geographic information spatially.
  • Choropleth Maps: Use colors to show data.
  • Dot Distribution Maps: Use dots to display data locations.
  • Graduated Symbol Maps: Use symbols of varying sizes for data representation.
  • Isoline Maps: Use lines to indicate data changes.
  • Cartograms: Distort shapes to display data differences.

Map Projections

  • Mercator Projection: True direction, distorted land masses.
  • Peters Projection: Accurate land size, distorted shapes.
  • Polar Projection: True direction from poles, edge distortion.
  • Robinson Projection: Compromise projection, equal distortion.

Geographic Data

  • Quantitative vs. Qualitative Data
    • Quantitative: Numerical data.
    • Qualitative: Descriptive data.
  • Data Collection
    • Individuals and organizations gather data.
    • Methods include geospatial technologies (GPS, GIS, remote sensing) and written accounts (field observation, media reports).

Geographic Decision Making

  • Using Data
    • Individuals, businesses, and governments use data for decision making.
    • Examples include travel planning, business locations, and government policy.

Geographic Concepts

  • Absolute and Relative Location
    • Absolute: Exact coordinates (latitude and longitude).
    • Relative: Location compared to another.
  • Space and Place
    • Space: Physical characteristics.
    • Place: Meaning attributed by people.
  • Flows
    • Patterns of interaction between locations.
  • Distance Decay
    • Less connection as distance increases.
  • Time-Space Compression
    • Decreased time or cost between places.
  • Patterns
    • Random, linear, dispersed arrangements of phenomena.

Human-Environment Interaction

  • Use of Resources
    • Renewable vs. non-renewable resources.
  • Sustainability
    • Study of resource use and environmental impact.
  • Land Use
    • Built environment and cultural landscape.

Theories of Interaction

  • Environmental Determinism
    • Environment shapes culture.
  • Possibilism
    • Humans shape culture within environmental opportunities.

Scales of Analysis

  • Global, Regional, National, Local
    • Varying sizes of data sets for analysis.
    • Larger scale: More detail; Smaller scale: Less detail.

Types of Regions

  • Formal Region
    • Linked by common traits.
  • Functional Region
    • Organized around a central node.
  • Perceptual Region
    • Defined by shared beliefs and feelings.
  • Contested Boundaries
    • Regions with disputed borders.
