Unit 1: Thinking Geographically Flashcards
Absolute Location
the exact position of an object or place stated in spatial coordinates or a grid system designed for locational purposes, e.g., latitude and longitude.
Built landscape
the part of the physical landscape that represents material culture; the buildings, roads, bridges, and similar structures large and small of the cultural landscape.
Cartogram
a map that has been simplified to present a single idea in a diagrammatic way: the base is not normally true to scale.
census
an official enumeration of the population, with details as to age, sex, occupation, etc. The USA has a census every ten years( 2010, 2020, 2030, etc.)
Choropleth
a thematic map in which ranked classes of some variable are depicted with shading patterns or colors for predefined zones.
Connectivity
the directness of routes linking pairs of places; an indication of the degree of internal connection in a transport network; all of the tangible and intangible means of connection and communication between places.
Contagious
the rapid, widespread diffusion of a feature or trend throughout a population; person to person spread of culture.
Arithmetic Density
the total number of people divided by the total land area.
Diffusion
the process of spread of a feature or trend from one place to another over time.
Distance decay
the diminishing in importance and eventual disappearance of a phenomenon with increasing distance from its origin.
Dot Map
a thematic map in which a dot represents some frequency of the mapped variable.
Environmental determinism
a nineteenth and early twentieth century approach to the study of geography that argued that the general laws sought by human geographers could be found in the physical sciences; physical environment caused human activities.
Equator
an imaginary east-west line that encircles the globe halfway between the North and South Poles
Formal Region
an area in which everyone shares in one or more distinctive characteristics (usually cultural).
Has clear, defined, and recognized boundaries
Ex. Africa, corn belt in the US
Friction of distance
a measure of the retarding or restricting effect of distance on spatial interaction; the greater the distance, the greater the “friction” and the less the interaction or exchange, or the greater the cost of achieving the exchange.
Functional Region (Nodal)
an area organized around a node or focal point
eg. a metro system
Geographic Information System (GIS)
a computer hardware and software system that handles geographically referenced data; it uses and produces maps and has the ability to perform many types of spatial analysis
geography
the study of the physical features of the earth and its atmosphere, and of human activity as it affects and is affected by these, including the distribution of populations and resources, land use, and industries. Describing the earth
geospatial
relating to or denoting data that is associated with a particular location
geospatial technology
refers to equipment used in visualization, measurement, and analysis of earth’s features, typically involving such systems as GPS (global positioning systems), GIS (geographical information systems), and RS (remote sensing).
Global Positioning System (GPS)
a system that determines the precise position of something on Earth through a series of satellites, tracking stations, and receivers
globalization
the tendency of businesses, technologies, or philosophies to spread throughout the world, or the process of making this happen
Hierarchical
the spread of a feature or trend from one key person or node of authority or power to other persons or places; spread of culture from one important / large area to another important / large area
hinterlands
either rural or urban or both, that is closely linked economically with a nearby town or city
