Geographic Information System (GIS)
a computer system that can capture, store, query, analyze, and display geographic data. Uses geocoding to calculate relationships between objects on a map's significance
Global Positioning System (GPS)
system that accurately determines the precise position of something on Earth, which includes several satellites in predetermined orbits and tracking stations to code the precise location of objects and reach a certain point
North and South Poles
the points farthest north and south on the Earth along its axis
Latitude
The numbering system to indicate the location of a parallel
Parallel
a circle draw around the globe parallel to the equator and at right angles to the meridians
Equator
an imaginary line around the Earth forming the great circle that is equidistant from the north and south poles
Longitude
the numbering system used to indicate the location of meridians drawn on a globe and measuring distance east and west of the Prime Meridian.
Meridian
An arc drawn between the North and South poles; A measure of Longitude
Prime Meridian
0 degrees Longitude
International Date Line
An arc that fro the most part follows 180� longitude, although it deviates in several place to avoid dividing land areas. When you cross it heading east, the clock moves back 24 hours, and when you cross it going west the calendar moves ahead one day.
Map
A two-dimensional or flat-scale model of Earth's surface, or a portion of it
Map scale
distance on a map relative to the distance on Earth
Thematic map
a map that demonstrates a particular feature or a single variable. Four types: dot, isoline, choropleth, and proportional symbol.
Dot Map
a thematic map in which a dot represents some frequency of the mapped variable
Cloropleth Map
a thematic map in which ranked classes of some variable are depicted with shading patterns or colors for predefined zones.
Isoline Map
a thematic map with lines that connect points of equal value.
Statistical Map
A special type of map in which the variation in quantity of a factor such as rainfall, population, or crops in a geographic area is indicated; such as a dot map
Cartogram
a map that has been simplified to present a single idea ina diagrammatic way: the base is not normally true to scale.
Mental Map
An internal representation of a portion of Earth's surface; depicting what an individual knows about a place -- containing personal impressions of what is in a place and where a place is located
Model

Demographic Transition
The process of change in a society's population from a condition of high crude birth and death rates and low rate of natural increase to a condition of low crude birth and death rates, low rate of natural increase, and a higher total population.
Epidemiological Transition

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.
Von Thunen Model
Model of agricultural land use, an agricultural model that spatially describes agricultural activity in terms of rent. Activities that require intensive cultivation and cannot be transported over great distances pay higher rent to be close to the market.
