the degree of ease with which it is possible to reach a certain location from other locations. Accessibility varies from place to place and can be measured.
physical geography
one of the two major divisions of systematic geography; the spatial analysis of the structure, processes, and location of the Earth's natural phenomena such as climate, soil, plants, animals, and topography.
connectivity
the degree of direct linage between one particular location and other locations in a transport network.
sequent occupance
the notion that successive societies leave their cultural imprints on a place, each contributing to the cumulative cultural landscape
spatial distribution
physical location of geographic phenomena across space
five themes (of geography)
they are location, human-environment, region, place, and movement
location theory
a logical attempt to explain the locational pattern of an economic activity and the manner in which its producing areas are interrelated. The agricultural location theory contained in the von Thunen model is a leading example.
medical geography
the study of health and disease within a geographic context and from a geographical perspective. Among other things, medical geography looks at sources, diffusions routes, and distribution of diseases.
spatial perspective
observing variations in geographic phenomena across space
human geography
one of the major divisions of geography; the spatial analysis of human population, its cultures, activities, and landscapes
epidemic
regional outbreak of a disease
cultural landscape
the visible imprint of human activity and culture on the landscape. The layers of buildings, forms, and artifacts sequentially imprinted on the landscape by the activities of various human occupants.
landscape
the overall appearance of an area. Most landscapes are comprised of a combination on natural and human-induced influences.
perception of place
belief or "understanding" about a place developed through books, movies, stories or pictures
sense of place
state of mind derived through the infusion of a place with meaning and emotion by remembering important events that occurred in that place or by labeling a place with a certain character.
pattern
the design of a spatial distribution (e.g. scattered or concentrated)
spatial
pertaining to space on the Earth's surface; sometimes used as a synonym for geographic
fieldwork
the study of geographic phenomena by visiting places and observing how people interact with and thereby change those places
place
the fourth theme of geography; uniqueness of a location
pandemic
an outbreak of a disease that spreads worldwide. (see also - endemic)
globalization
the expansion of economic, political, and cultural processes to the point that they become global in scale and impact. The processes of globalization transcend state boundaries and have outcomes that vary across places and scales.
location
the first theme of geography as defined by the Geography Educational National Implementation Project; the geographical situation of people and things.
distance
measurement of the physical space between two places
spatial interaction
see complementarity (a condition that exists when two regions, through an exchange of raw materials and/or finished products, can specifically satisfy each others demands) and intervening opportunity (the presence of a nearer opportunity that greatly diminishes the attractiveness of sites farther away)
human-environment
the second theme of geography; reciprocal relationship between humans and environment.
region
the third theme of geography; an area on the Earth's surface marked by a degree of formal, functional, or perceptual homogeneity of some phenomenon
movement
the fifth theme of geography; the mobility of people, goods, and ideas across the surface of the planet.
reference maps
Maps that show the absolute location of places and geographic features determined by a frame of reference, typically latitude and longitude
absolute locations
The position or place of a certain item on the surface of the Earth as expressed in degrees, minutes, and seconds of latitude, 0° to 90° north or south of the equator, and longitude, 0° to 180° east or west of the Prime Meridian passing through Greenwich, England (a suburb of London)
possibilism
Geographic viewpoint—a response to determinism—that holds that human decision making, not the environment, is the crucial factor in cultural development. Nonetheless, possibilists view the environment as providing a set of broad constraints that limits the possibilities of human choice
relocation diffusion
Sequential diffusion process in which the items being diffused are transmitted by their carrier agents as they evacuate the old areas and relocate to new ones. The most common form of relocation diffusion involves the spreading of innovations by a migrating population
cultural hearth
Heartland, source area, innovation center; place of origin of a major culture
generalized map
"When mapping data, whether human or physical geographers, cartographers, the geographers who make maps, generalize the information the present on maps." (de Blij, Murphey, Fouberg, ph 16)
cultural barriers
Prevailing cultural attitude rendering certain innovations, ideas or practices unacceptable or unadoptable in that particular culture
rescale
Involvement of players at other scales to generate support for a position or an initiative (e.g., use of the Internet to generate interest on a national or global scale for a local position or initiative)
contagious diffusion
The distance-controlled spreading of an idea, innovation, or some other item through a local population by contact from person to person—analogous to the communication of a contagious illness
hierarchical diffusion
A form of diffusion in which an idea or innovation spreads by passing first among the most connected places or peoples. An urban hierarchy is usually involved, encouraging the leapfrogging of innovations over wide areas, with geographic distance a less important influence
global positioning systems (GPS)
Satellite-based system for determining the absolute location of places or geographic features
stimulus diffusion
A form of diffusion in which a cultural adaptation is created as a result of the introduction of a cultural trait from another place
formal region
A type of region marked by a certain degree of homogeneity in one or more phenomena; also called uniform region or homogeneous region
