Direction, Distance, and Location

Absolute direction — A precise direction based on the cardinal directions: north, south, east, and west.

Relative direction — A direction described in relation to another location, such as “west of the school.”

Absolute distance — The exact distance between two places, usually measured in units such as miles or kilometers.

Relative distance — Distance measured by how much time, cost, or effort it takes to travel between places.

Absolute location — The exact position of a place, usually given by coordinates such as latitude and longitude.

Relative location — The location of a place in relation to other places or landmarks.

Maps and Mapping

Cartography — The science and art of making maps.

Map projection — A method of representing Earth's curved surface on a flat map. Every projection causes some distortion.

Mercator projection — A map projection that preserves direction and shape fairly well but greatly exaggerates the size of areas near the poles.

Robinson projection — A projection designed to make the entire world look visually balanced by reducing extreme distortion.

Homolosine projection — A projection that reduces distortion of area and shape by dividing the map into sections; it often looks interrupted.

Map scale — The relationship between distance on a map and actual distance on Earth.

Types of Map Scale

Graphic scale — A visual line on a map showing actual distances.

Representative fraction — A ratio showing map distance to real-world distance, such as 1:100,000.

Word statement — A written description of scale, such as “1 inch represents 10 miles.”

Types of Maps

Reference map — Shows general geographic information, such as roads, cities, rivers, and borders.

Thematic map — Shows information about a particular topic or theme.

Physical map — Shows natural features such as mountains, rivers, and elevation.

Political map — Shows human-created boundaries such as countries, states, and cities.

Data

Census data — Information collected about a population, such as age, income, race, and population size.

Qualitative Data

Qualitative data — Non-numerical information describing characteristics, experiences, opinions, or observations.

Examples:

Field observations/study — Information gathered by directly observing a place or people in the field.

Media reports — Information gathered from news, television, websites, or other media.

Personal interviews — Information collected by asking people questions directly.

Travel narratives — Written descriptions of places based on someone's travel experiences.

Photographic interpretation — Learning about a place by examining photographs and identifying geographic features.

Quantitative Data

Quantitative data — Numerical information that can be measured or counted.

Examples:

Census — Numerical population information collected by a government.

Property values — Numerical information about how much properties are worth.

Tax rolls — Government records showing property values and taxes owed.

Climate and Environment

Climate — The long-term pattern of weather in a particular area.

Elevation — The height of a place above sea level.

Natural resources — Materials or substances from nature that humans use, such as water, forests, minerals, and fossil fuels.

Topography — The arrangement and shape of the physical features of Earth's surface, including mountains, valleys, and plains.

Land use — How humans use a particular piece of land, such as for farming, housing, industry, or recreation.

Human-Environment Relationships

Cultural ecology — The study of how people and their cultures interact with and adapt to their environment.

Environmental determinism — The belief that the physical environment determines or strongly controls human behavior and culture.

Possibilism — The idea that the environment provides opportunities and limits, but humans choose how to use those opportunities.

Easy way to remember:

Determinism = environment controls people.

Possibilism = environment gives possibilities; people make choices.

Sustainability — Using resources in a way that meets current needs without preventing future generations from meeting theirs.

Spatial Patterns

Pattern — The arrangement of geographic features or phenomena across space.

Common Patterns

Linear pattern — Features arranged in a line, often along a road, river, or coastline.

Centralized pattern — Features concentrated around a central point.

Random pattern — Features arranged without a clear or predictable pattern.

Clustering — The grouping of similar features or activities close together.

Concentration — The degree to which something is spread out or grouped together in an area.

Dispersal — The spreading of people or things over an area.

Distribution — The arrangement of a phenomenon across geographic space.

Place

Place — A specific location that has physical and human characteristics that give it meaning.

Site — The physical characteristics of a location, such as climate, landforms, soil, and water.

Situation — The location of a place relative to other places and surrounding features.

Sense of place — The feelings, meanings, and connections people have toward a particular place.

Placelessness — The loss of a place's unique identity because similar businesses, buildings, landscapes, and cultures appear everywhere.

Site vs. Situation:

Site = what's physically there.

Situation = where it is compared with everything around it.

Space

Space — The physical area or distance between locations and the way things are arranged across Earth's surface.

Spatial systems — Systems and technologies used to collect, analyze, and understand geographic information.

Geospatial Technologies

Geographic Information System (GIS) — A computer system used to collect, store, analyze, and display geographic data on maps.

GPS (Global Positioning System) — A satellite-based system that determines the precise location of something on Earth.

Satellite imagery — Images of Earth's surface taken by satellites orbiting Earth.

Satellite navigation systems — Systems that use satellites to determine location and provide navigation or directions.

Remote sensing — Collecting information about Earth's surface from a distance, usually using satellites or aircraft.

Easy distinction:

GIS = analyzes/maps data.

GPS = tells you where you are.

Remote sensing = collects information from far away.

Satellite imagery = pictures/data of Earth from satellites.

Regions

Region — An area of Earth that shares one or more characteristics.

Types of Regions

Formal region — An area where everyone or everything shares a clearly defined characteristic.

Example: A country, state, or area where a particular language is spoken.

Functional region — An area organized around a central point or node and connected through interactions.

Example: A city's subway system or the area served by a hospital.

Perceptual/vernacular region — An area people believe exists based on their opinions, feelings, or perceptions.

Example: “The South,” “the Midwest,” or “New England.”

Easy way to remember:

Formal = same characteristic

Functional = connected to a central point

Perceptual = people's ideas/opinions

Diffusion

Diffusion — The spread of an idea, innovation, cultural trait, or phenomenon from one place to another.

Types of Diffusion

Relocation diffusion — A cultural trait spreads because people physically move to a new location.

Example: Immigrants bringing their religion or food traditions to another country.

Hierarchical diffusion — An idea spreads from influential people or places to others.

Example: A fashion trend adopted by celebrities and then by the general public.

Contagious diffusion — An idea spreads rapidly from person to person or place to place, similar to the spread of a disease.

Example: A viral trend spreading through a community.

Stimulus diffusion — An idea spreads but is changed or adapted to fit the new culture.

Example: A fast-food restaurant adapting its menu to local tastes.

Cultural diffusion — The general spread of cultural traits, ideas, technologies, languages, religions, or practices between societies.

Distance and Connectivity

Distance decay — The idea that interaction between places generally decreases as the distance between them increases.

Example: You are more likely to regularly visit a store 2 miles away than one 200 miles away.

Time-space compression — The reduction in the time it takes to travel or communicate between places because of improved transportation and technology.

Example: The internet allows someone in Texas to communicate instantly with someone in Japan.

Globalization — The increasing connection and interaction between people, economies, cultures, and places around the world.

Landscape

Cultural landscape — The visible features of an area that reflect human culture and activity.

Examples: Buildings, roads, farms, religious structures, signs, and architecture.

Landscape analysis — Studying the visible features of a landscape to understand the human and physical processes that created it.

Scale

Scale — The level at which a geographic phenomenon is studied.

Geographic Scales

Local scale — A small area, such as a neighborhood or city.

Regional scale — A larger area containing multiple places that share characteristics.

National scale — An entire country.

Global scale — The entire world.

Important: Map scale and geographic scale are related but not the same thing. Map scale describes the relationship between map distance and real distance, while geographic scale describes the level at which a geographic issue is examined.

Location and Resources

Location — The position of something on Earth's surface.

Land use — The way humans use land for activities such as agriculture, housing, transportation, business, or recreation.

Natural resources — Useful materials and features provided by nature, such as water, soil, forests, minerals, and fossil fuels.
