Relative Location

A description of where something is located in relation to other features, often expressed in terms of connectivity and accessibility.

Connectivity

How well two locations are tied together or linked by roads, transit, or communication systems.

Accessibility

The ease and speed with which people in one location can reach or interact with people in another location.

Direction

The course along which someone or something moves or points, specified using cardinal directions (north, south, east, west) or intermediate directions.

Absolute Distance

The exact physical measurement between two points, expressed in quantitative units such as feet, miles, meters, or kilometers.

Relative Distance

A measurement of nearness between locations based on travel time or monetary cost.

Elevation

The vertical distance of physical or human features measured above sea level, typically recorded in feet or meters.

Distribution

The way in which a phenomenon is spread out or arranged across a specific area.

Clustered Distribution

A spatial arrangement in which items or phenomena are grouped or concentrated closely together.

Dispersed Distribution

A spatial arrangement in which items or phenomena are spread out widely over a large area.

Linear Distribution

A spatial arrangement in which phenomena are positioned in a straight line, such as along a river, road, or railroad.

Circular Distribution

A spatial arrangement in which phenomena are equally spaced around a central point, forming a circle.

Geometric Distribution

A spatial arrangement in which phenomena form a regular grid or geometric pattern, such as square blocks formed by roads.

Random Distribution

A spatial arrangement in which phenomena appear to have no predictable order or pattern in their positions.

Map Projection

The mathematical process of representing the three-dimensional, spherical surface of the Earth on a flat, two-dimensional map.

Mercator Projection

A map projection designed for navigation that preserves straight directional lines, but severely distorts landmass sizes toward the poles.

Peters Projection

An equal-area map projection that keeps landmass areas accurate in proportion to one another while distorting their shapes near the poles.

Conic Projection

A map projection best suited for midlatitude regions, where lines of longitude converge toward a pole and latitude lines are curved.

Robinson Projection

A general-use map projection featuring an oval shape that slightly distorts area, shape, size, and direction to achieve a realistic globe-like appearance.

Field Observation

The act of physically visiting a location or region to observe, measure, and record firsthand spatial data.

Remote Sensing

The acquisition of spatial data about Earth's surface from orbiting satellites or high-altitude sensors without physical contact.

Aerial Photography

Professional pictures taken from aircraft within Earth's atmosphere to capture observed landscape features.

Fieldwork

The practice of collecting geospatial data on location through direct observations, interviews, measurements, sketches, and surveys.

Global Positioning System (GPS)

A network of satellite-based receivers used to determine and record exact absolute locations on Earth's surface.

Geographic Information System (GIS)

A computer hardware and software system used to store, analyze, manipulate, and display layered geographic data sets.

Geovisualization

Interactive 2D or 3D digital map graphics that allow users to visualize, zoom, and analyze spatial data.

Spatial Interaction

The contact, movement, and flow of people, goods, services, or ideas between different geographic locations.

Flow

The movement and patterns of people, ideas, products, and other phenomena across space.

Friction of Distance

The concept that distance acts as an obstacle to movement and interaction, causing connection to diminish over greater distances.

Distance Decay

The principle that the degree of interaction or connection between two places decreases as the distance between them increases.

Time-Space Compression

The reduction in travel time and apparent relative distance between locations brought about by advancements in transportation and communication.

Spatial Association

The degree to which two or more geographic distributions share similar spatial patterns, suggesting a potential relationship.

Site

The immediate physical and human characteristics of a specific location, such as its climate, terrain, soil type, and structures.

Situation

The location of a place relative to its surrounding features and its degree of connectivity to other places.

Sense of Place

The emotional connection, meaning, and perception that humans attribute to a specific place based on personal or cultural experiences.

Placelessness

A condition in which a location lacks unique individual characteristics and inspires no strong emotional attachment.

Toponym

A name given to a place on Earth, often reflecting its physical environment, history, culture, or ownership.

Human-Environmental Interaction

The dynamic, two-way relationship and reciprocal exchanges between human societies and the natural environment.

Natural Resource

Materials or substances occurring in nature that humans can utilize for economic or survival benefits.

Renewable Natural Resource

A natural resource that can replenish itself naturally or is virtually inexhaustible over time, such as solar or wind energy.

Non-renewable Natural Resource

A natural resource present in finite amounts that is depleted faster than it can naturally form, such as fossil fuels.

The study of how human societies adapt to and modify their surrounding natural environments.

Environmental Determinism

The theory that physical features, particularly climate and landforms, dictate human behavior and culture.

Possibilism

The theory that the physical environment sets limits on human actions, but human culture and technology allow people to adapt and overcome those limits.

Geographic Scale

Also called relative scale, the spatial extent or scope of the world being analyzed (e.g., global, regional, national, local).

Scale of Analysis

The level at which spatial data is grouped or aggregated on a map or chart to reveal geographic patterns.

Aggregation

The grouping and organizing of spatial data into specific categories or administrative units (such as census tracts, counties, or nations).

Region

An area of the Earth defined by shared unifying characteristics, spatial extent, and boundaries.

Formal Region

Also called a uniform or homogeneous region, an area united by one or more common physical, political, cultural, or economic traits.

Functional Region

Also called a nodal region, an area organized around a central focal point or node, linked by transportation or communication networks.

Perceptual Region

Also called a vernacular region, an area defined by people's subjective, informal beliefs and sense of place rather than exact objective boundaries.

Subregion

A smaller division of a larger world region that shares overarching regional traits but exhibits distinct local characteristics.
