Chapter 1 Flashcards
Accessibility
The opportunity for contact or interaction from a given point or location in relation to other locations.
Areal units
Spatial units of measurement, such as a city block or province, used for recording statistics.
Azimuthal projections
When compass directions are correct only from one central point.
Cartogram
One map projection used in small scale thematic maps.
Cartography
The art and science of making maps.
Cognitive images (mental maps)
Psychological representations of locations that are created from people’s individual ideas and impressions of these locations.
Complementarity
A demand in one place and a supply complementing it in the other. Example is flow of oil to Japan who has none.
Choropleth map
Tonal shadings are graduated to reflect variations in numbers, frequencies, or densities.
Conformal projections
Map projections on which compass bearings are rendered accurately.
Cognitive space
Space defined and measured in terms of people’s values, feelings, beliefs, and perceptions about places and regions.
Cognitive distance
The distance that people perceive to exist in a given situation.
Contour
A line that connects points of equal elevation above sea level.
Distance-decay function
The rate at which a particular activity or process diminishes with increasing distance.
Economies of scale
Cost advantages to manufacturers that accrue from high volume production, since the average cost of production falls with increasing output.
Equidistant projections
Map projections that represent distance accurately in only one direction (usually North-south), although they usually provide accurate scale in the perpendicular direction (which in most cases is the equator).
Dot maps
A single dot or other symbol represents a specified number of occurrences of some particular phenomenon or event.
Equal-area equivalent projections
Map projections that portray areas on Earth’s surface in their true proportions.
Friction of distance
The deterrent or inhibiting effect of distance on human activity. (Time and cost of overcoming distance).
Functional regions (nodal regions)
Regions that, while they may exhibit some variability in certain attributes, share an overall coherence in structure and economic, political, social organization.
Geodemographic research
Investigation using census data and commercial data like sales data and property records, about the populations of small districts to create profiles of those populations for market research.
Geographic information system (GIS)
An organized set of computer hardware, software, and spatially coded data that is designed to capture, store, update, manipulate, and display spatially referenced information.
Geographical imagination
A capacity that allows us to understand changing patterns, processes, and relationships among people, places, and regions.
Global Positioning System (GPS)
A system of satellites that orbit Earth on precisely predictable paths, broadcasting highly accurate time and locational information.
