Accessibility

The relative ease with which a destination may be reached from some other location.

GIS

Geographic Information Systems; a computer system that stores, organizes, analyzes, and displays geographic data.

GPS

Distance decay

The diminishing in importance and eventual disappearance of a phenomenon with increasing distance from its origin.

Time-space compression

The reduction in the time it takes to diffuse something to a distant place as a result of improved communications and transportation systems.

Formal/uniform/homogenous regions

Qualitative data

Information that is descriptive and conceptual, such as field observations, media reports, or interviews.

Friction of distance

A measure of how much absolute distance affects the interaction between two places.

Choropleth map

A thematic map that uses tones or colors to represent spatial data as average values per unit area.

Cartogram map

A map in which some thematic mapping variable—such as population or GDP—is substituted for land area or distance.

Isoline map

A thematic map with lines that connect points of equal value, commonly used for representing elevation or weather.
