AP Human Geography Unit 1

Introduction

• Understanding and interpreting geographic data is crucial.
• Maps are the most important tools for geographers, showing spatial patterns.
• Spatial patterns describe the location of features on Earth (e.g. mountains, highways, demographics).

Geographic Data

Types of Spatial Patterns

1. Absolute and Relative Distance
   • Absolute distance: measurable units (inches, feet, miles, kilometers).
   • Relative distance: social, cultural, or political differences.
2. Absolute and Relative Direction
   • Absolute direction: cardinal points (north, south, east, west).
   • Relative direction: position in relation to another (e.g. "down to Atlanta").
3. Clustering and Dispersal
   • Clustering: phenomena are close together.
   • Dispersal: phenomena are spread out.
4. Elevation
   • Height relative to sea level, shown on isoline maps.

Map Features

• Scale: Relates map distance to real-world distance (e.g. 1:1000 scale).
• Compass Rose: Depicts direction (cardinal and intermediate).

Types of Maps

1. Reference Maps
   • Show specific geographic locations (e.g. road maps, topographical maps).
2. Thematic Maps
   • Show geographic information or themes (e.g. political, demographic).
   • Types include choropleth, dot distribution, graduated symbol, isoline, and cartogram maps.

Map Projections

• Mercator Projection: True direction, but distorts size near poles.
• Peters Projection: Accurate size, distorted shape.
• Polar Projection: Edge distortion, true direction.
• Robinson Projection: Compromise with balanced distortions.

Geographic Data Collection

Types of Data

1. Quantitative Data: Numerical (e.g. population counts).
2. Qualitative Data: Descriptive (e.g. community satisfaction).

Data Gathering Entities

• Individuals: Researchers, community advocates.
• Organizations: U.S. Census Bureau, etc.

Methods of Data Collection

• Geospatial Technologies: GPS, GIS, remote sensing.
• Written Accounts: Field observations, media reports, travel narratives.

Geographic Concepts

Major Concepts

1. Absolute and Relative Location
   • Absolute: Latitude and longitude.
   • Relative: Position in relation to another location.
2. Space and Place
   • Space: Physical characteristics, measurable.
   • Place: Meaning attributed by people.
3. Flows: Patterns of spatial interaction (e.g. road connectivity).
4. Distance Decay: Decreased interaction with increased distance.
5. Time-Space Compression: Decreased travel time due to advancements.
6. Patterns: Arrangement of phenomena (random, linear, dispersed).

Human-Environmental Interaction

1. Use of Natural Resources
   • Renewable vs non-renewable resources.
2. Sustainability
   • Resource use policies, pollution impact.
3. Land Use
   • Built environment and cultural landscapes.

Theories

1. Environmental Determinism
   • Environment shapes culture.
2. Possibilism
   • Humans shape culture, environment offers possibilities.

Scales of Analysis

Types of Scales

1. Global Scale: Entire Earth.
2. Regional Scale: Large regions.
3. National Scale: Within a country.
4. Local Scale: State, city, neighborhood.

Key Points

• Zooming in increases scale; zooming out decreases scale.
• Different scales reveal different patterns and processes.

Regions

Types of Regions

1. Formal Region: Shared traits (language, economic).
2. Functional Region: Shared function (nodal regions).
3. Perceptual Region: Based on shared beliefs, vague boundaries.

Contested Boundaries

• Regions with disputed borders, e.g., Kashmir.
