AP Human Geography Unit 1: Thinking Geographically Study Guide
Topic 1.1: Introduction to Maps
Suggested Skill:
- Skill 3.A (Data Analysis): Identify the different types of data presented in maps and in quantitative and geospatial data.
Enduring Understanding:
- IMP-1: Geographers use maps and data to depict relationships of time, space, and scale.
Learning Objective:
- IMP-1.A: Identify types of maps, the types of information presented in maps, and different kinds of spatial patterns and relationships portrayed in maps.
Essential Knowledge:
- IMP-1.A.1: Types of maps include reference maps and thematic maps.
- Reference Maps: Focus on showing the locations of landforms, natural features, and political boundaries (e.g., topographic maps, road maps, physical maps).
- Thematic Maps: Focus on displaying spatial patterns of specific attributes, data, or themes (e.g., choropleth, dot density, proportional symbol, isoline, and cartograms).
- IMP-1.A.2: Types of spatial patterns represented on maps include absolute and relative distance and direction, clustering, dispersal, and elevation.
- Absolute Distance: Exact spatial measurement expressed in standard numerical units such as miles or kilometers.
- Relative Distance: Measurement of spatial separation based on travel time, monetary cost, or degree of connectivity.
- Absolute Direction: Precise direction derived from compass bearings (e.g., North, South, East, West, East).
- Relative Direction: Direction expressed using social or cultural references (e.g., "out West", "down South", "left of the store").
- Clustering: The degree to which geographic features or phenomena group closely together in space.
- Dispersal: The degree to which geographic features or phenomena are spread out or scattered across space.
- Elevation: The height of physical land features above a baseline standard, typically sea level.
- IMP-1.A.3: All maps are selective in information; map projections inevitably distort spatial relationships in shape, area, distance, and direction.
- Map Selectivity: Maps intentionally omit certain spatial elements to highlight specific data clearly.
- Spatial Distortion: Transferring a three-dimensional spherical surface (Earth) onto a two-dimensional flat plane inherently creates distortion across four properties:
- Shape: Conformal projections alter spatial size to preserve localized landform angles and shapes.
- Area: Equal-area projections preserve accurate proportional surface areas while distorting landmass shapes.
- Distance: Distortions alter actual linear distances across locations on the grid.
- Direction: Distortions warp true cardinal directions across map coordinates.

- Absolute Location: The definitive coordinate point of a feature on Earth's surface defined by latitude and longitude or a specific street address.
- Relative Location: The location of a site described in relation to other physical landmarks, human features, or spatial reference points.
- Space: The physical or abstract geometric area, interval, or extent existing between features or across the Earth's surface.
- Place: A specific point on Earth defined by unique physical and human characteristics that impart distinctive identity and human sense of place.
- Flows: Spatial movement of people, commodities, information, money, ideas, and cultural attributes between distinct geographic locations.
- Distance Decay: The principle stating that spatial interaction or contact between two points diminishes as the physical distance between them increases.
- Time-Space Compression: The perceived reduction in spatial distance and travel time brought about by technological breakthroughs in transportation and telecommunications.

- Land Use: Human management, modification, and spatial allocation of natural environments for functional purposes such as agriculture, industry, residential housing, or recreation.
- PSO-1.B.2: Theories regarding the interaction of the natural environment with human societies have evolved from environmental determinism to possibilism.
- Environmental Determinism: The historical theoretical view proposing that the natural environment (specifically physical geography and climate) dictates, controls, and limits human intelligence, cultural evolution, and societal development.
- Possibilism: The modern theoretical view asserting that while the physical environment imposes constraints, human societies possess the adaptive capacity, cultural innovation, and technology to overcome environmental limits and choose among diverse spatial opportunities.

Learning Objective:
- SPS-1.A: Describe different ways that geographers define regions.
Essential Knowledge:
- SPS-1.A.1: Regions are defined on the basis of one or more unifying characteristics or on patterns of activity.
- Geographic regions are delineated by common shared physical attributes (e.g., climate, topography) or shared human attributes (e.g., language, agricultural practices, economic function).
- SPS-1.A.2: Types of regions include formal, functional, and perceptual/vernacular.
- Formal (Uniform / Homogeneous) Region: An area marked by a shared physical or cultural feature across its entire extent, bounded by clear official borders (e.g., state lines, language zones, climate classifications).
- Functional (Nodal) Region: An area organized around a central focal node or hub, linked to surrounding territory by transportation routes, economic transactions, or communication networks (e.g., subway networks, metropolitan media markets, airport hubs).
- Perceptual (Vernacular) Region: An area defined by informal human perceptions, cultural identity, mental maps, and shared subjective beliefs rather than strict scientific or legal boundaries (e.g., the American "South", the "Rust Belt").
- SPS-1.A.3: Regional boundaries are transitional and often contested and overlapping.
- Boundaries between adjacent geographic regions rarely form sharp lines; instead, they display gradual spatial transition zones that overlap and undergo ongoing political, social, or cultural dispute.
- SPS-1.A.4: Geographers apply regional analysis at local, national, and global scales.
- Regional frameworks are applied across multiple hierarchical scales to investigate human and physical spatial processes.
