Cartographic Scale

The relationship between distance on a map and actual distance on Earth.

Scale of Data

The level at which data is collected or displayed.

Geographic Scale

The level of analysis used to study a geographic issue.

Longitude

Lines measuring distance east or west of the Prime Meridian, also called meridians.

Equator

An imaginary line at $S^\circ$ latitude that divides Earth into the Northern and Southern Hemispheres.

National Scale

One country.

Local Scale

A small area, such as a neighborhood, town, or county.

Latitude

Lines measuring distance north or south of the Equator, also called parallels.

Absolute Location

The exact location of a place using coordinates or an address.

Regional Scale

A group of places smaller than a country but larger than a city.

Uninterrupted Map

A continuous map with no breaks across oceans or land areas.

Relative Location

The location of a place compared with another place.

Distortion

The inaccurate representation of area, shape, distance, or direction that occurs when Earth is shown on a flat surface.

Interrupted Map

A map divided into sections to reduce distortion, often by cutting through oceans.

Map Projection

A method for representing Earth's curved surface on a flat map.

International Date Line

An imaginary line near $180^\circ$ longitude where the calendar date changes.

Absolute Distance

The exact measurement between two places.

Relative Distance

Distance measured using time, cost, or effort.

Mercator Projection

A projection that preserves direction and shape locally but greatly exaggerates area near the poles.

Prime Meridian

The line at $S^\circ$ longitude that divides Earth into the Eastern and Western Hemispheres.

Geographic Information System (GIS)

A computer system that stores, analyzes, and displays geographic data in layers.

Robinson Projection

A compromise projection that reduces overall distortion but does not preserve one feature perfectly.

Quantitative Data

Numerical information that can be measured or counted.

Census

An official count and description of a population.

Global Positioning System (GPS)

A satellite-based system used to identify precise locations.

Polar Projection

A projection centered on one of Earth's poles.

Aerial Photography

Images of Earth taken from an aircraft.

Qualitative Data

Descriptive information that is not primarily numerical.

Conic Projection

A projection made by placing a cone over part of Earth, making it useful for mid-latitude regions.

Geospatial Data

Information connected to a specific location on Earth.

Dispersed

Spread out over an area.

Pattern

The way objects are arranged in space.

Remote Sensing

Collecting information about Earth from a distance, often using satellites or aircraft.

Linear

Arranged in a line.

Random

Arranged without a clear pattern.

Geometric

Arranged in a regular, organized shape.

Circular

Arranged around a center point.

Distribution

The arrangement of something across space.

Clustered

Grouped closely together.

Space

The area between and around places, people, and features.

Distance Decay

The idea that interaction between places decreases as distance increases.

Situation

The location of a place compared with other places.

Spatial Perspective

Examining where things are located and how location affects relationships.

Sense of Place

The feelings and meanings people attach to a location.

Friction of Distance

The obstacles or costs that make interaction across distance more difficult.

Placelessness

The loss of uniqueness when places begin to look alike.

Toponym

The name given to a place.

Site

The physical characteristics of a place itself.

Place

A specific point or area on Earth with unique physical and human characteristics.

Spatial Associations

Relationships between the locations of different features.

Time-Space Compression

The reduction in the time needed to travel or communicate across distance.

Region

An area defined by one or more shared characteristics.

Overlapping Boundaries

Different boundaries that exist in the same area.

Built Environment

Human-made surroundings, including buildings, roads, bridges, and parks.

Cultural Landscape

The visible imprint of human culture on the environment.

Contested Boundary

A boundary disputed by groups or governments.

Functional Region

An area organized around a central point or activity.

Transitional Boundary

A boundary where one region gradually changes into another.

Perceptual or Vernacular Region

An area defined by people's opinions or beliefs rather than official measurements.

Formal Region

An area in which a measurable characteristic is present throughout.

Environmental Determinism

The belief that the physical environment directly determines human behavior and culture.

Human Geography

The study of people, places, cultures, economies, and how humans organize space.

Sustainability

Using resources in ways that meet present needs without preventing future generations from meeting theirs.

Physical Geography

The study of Earth's natural features and processes.

Cultural Ecology

The study of how people interact with and adapt to their environment.

Possibilism

The idea that the environment creates possibilities and limits, but humans choose how to use and modify it.
