Ch 1: Thinking Geographically Vocab Flashcards
Absolute Distance
A distance that can be measured with a standard unit of length, such as a mile or a kilometer.
Absolute Location
The exact position of an object or place, measured within the spatial coordinates of a grid system.
Accessibility
The relative ease with which a destination may be reached from some other place.
Aggregation
To come together into a mass, sum or whole.
Azimuthal Projection
A map projection in which the plane is the most developable surface.
Breaking Point
The outer edge of a city’s sphere of influence, used in the law of retail gravitation to describe the area of the city’s hinterlands that depend on that city for its retail supplies.
Cartograms
A type of thematic map that transforms space such that the political unit with the greatest value for some type of data is represented by the largest relative area.
Cartography
The theory and practice of making visual representations of Earth’s surface in the form of maps.
Choropleth Map
A thematic map that uses tones or colors to represent spatial data as average values per unit area.
Cognitive Map
An image of a portion of Earth’s surface that an individual creates in their mind. Cognitive maps can include knowledge of actual locations and relationships among locations as well as personal perceptions and preferences of particular places.
Complementary
The actual or potential relationship between two places, usually referring to economic interventions.
Connectivity
The degree of economic, social, cultural, or political connection between two places.
Contagious Diffusion
The spread of a disease, an innovation, or cultural traits through direct contact with another person or another place.
Coordinate System
A standard grid, composed of lines of latitude and longitude, used to determine the absolute location of any object, place, or feature on Earth’s surface.
Cultural Ecology
Also called nature-society geography, the study of the interactions between societies and the natural environments in which they live.
Cultural Landscape
The human-modified natural landscape specifically containing the imprint of a particular culture or society.
Distance Decay Effect
The decrease in interaction between two phenomena, places, or people as the distance between them increases.
Dot Maps
Thematic maps that use points to show the precise locations of specific observation or occurrences, such as crimes, car accidents, or births.
Environmental Geography
The intersection between human and physical geography, which explores the spatial impacts humans have on the physical environment or vice versa.
Expansion Diffusion
The spread of ideas, innovations, fashion or other phenomena to surrounding areas through contact and exchange.
Formal Region
Definition of regions based on common themes such as similarities in language, climate, land use etc.
Friction of Distance
A measure of how much absolute distance affects the interaction between two places.
Fuller Projection
A type of map projection that maintains the accurate size and shape of landmasses but completely rearranges direction such that the four cardinal directions–north, south, east, and west–no longer have any meaning.
Functional Region
Definition of regions based on common interaction (or function)–for example, a boundary line drawn around the circulation, of a particular newspaper.
Geographic Information System (GIS)
A set of computer tools used to capture, store, transform, analyze, and display geographic data.
Geographic Scale
The scale at which a geographer analyzes a particular phenomenon–for example, global, national, census tract, neighborhood, etc. Generally, the finer the scale of analysis, the richer the level of detail in the findings.
Global Positioning System (GPS)
A set of satellites used to help determine location anywhere on Earth’s surface with a portable electronic device.
Gravity Model
A mathematical formula that describes the level of interaction between two places, based on the size of their populations and their distance from each other.
Hierarchical Diffusion
A type of diffusion in which something is transmitted between places because of a physical or cultural community between those places.
Human Geography
The study of the spatial variation in the patterns and processes related to human activity.
International Date Line
The line of longitude that marks where each new day begins, centered on the 180th meridian.
Intervening Opportunity
If one place has a demand for some good or service and two places have a supply of equal price and quality, the supplier closer to the buyer will represent an intervening opportunity, thereby blocking the third from being bale to share its supply of goods or services. Intervening opportunities are frequently used because transportation costs usually decrease with proximity.
Isoline
A map line that connects points of equal or very similar values.
Large Scale
A relatively small ratio between map units and ground units. large-scale maps usually have higher resolution and cover much smaller regions than small-scale maps.
Latitude
The angular distance north or south of the equator, defined by lines of latitude or parallels.
Law of Retail Gravitation
A law stating that people will be drawn to larger cities to conduct their business since larger cities have a wider influence on the surrounding hinterlands.
Location Chart
On a map, a chart or graph that gives specific statistical information about a particular political unit or jurisdiction.
Longitude
The angular distance east or west of the prime meridian, defined by lines of longitude, or meridians.
Map Projection
A mathematical method that involves transferring Earth’s sphere onto a flat surface. This term can also be used to describe the type of map that results from the process of projecting. All map projections have distortions in area, direction, distance, or shape.
Map Scale
The ratio between the size of an area on a map and the actual size of that same area on Earth’s surface.
Mercator Projection
A true conformal cylindrical map projection, the Mercator map projection is particularly useful for navigation since it maintains accurate direction. Mercator projections are famous for their distortion in area that makes landmasses at the poles appear oversized.
Meridian
A line of longitude that runs north-south. All lines of longitude are equal in length and intersect at the poles.
Natural Landscape
The physical landscape or environment that has not been affected by human activities.
Nature-Society
Also called nature-society geography, the study of the interactions between societies and the natural environments in which they live.
Parallel
An east-west line of latitude that runs parallel to the equator and that marks distance north or south of the equator.
W. D. Pattison
Geographer who claimed that geography drew from four distinct traditions: the earth-science tradition, the culture-environment tradition, the locational tradition, and the area-analysis tradition.
Perceptual Region
Highly individualized definition of regions based on perceived commonalities in culture and landscape.
Peters Projection
An equal-area projection purposely centered on Africa in an attempt to treat all regions of Earth equally.
Physical Geography
The realm of geography that studies the structures, processes, distributions, and changes through time of the natural phenomena of Earth’s surface.
Preference Map
A map that displays individual preferences for certain places.
Prime Meridian
An imaginary line passing through the Royal Observatory in Greenwich, England, that marks the 0 degree line of longitude.
Projection
The system used to transfer locations from Earth’s surface to a flat map.
Proportional Symbols Map
A thematic map in which the size of a chosen symbol–such as a circle or triangle–indicates the relative magnitude of some statistical value for a given geographic region.
