A two-dimensional or flat-scale model of Earth's surface, or a portion of it.
The relationship between the portion of Earth being studied and Earth as a whole.
Of or pertaining to space on Earth's surface.
An area of Earth distinguished by a distinctive combination of cultural and physical features.
Referring to the relationship of a feature's size on a map to its actual size on Earth. Can be presented in three ways: fraction, ratio , and a written statement.
Distortion of Maps
"All maps lie flat and all maps lie." Four types of distortion. Shape, Distance, Relative Size, and Direction.
(Geographic Information System)
A computer system that can capture, store, query, analyze and display geographic data. Can be used to produce maps storing each type of information in layers.
(Global Positioning Satellite)
A system that accurately determines the precise position of something on Earth.
The acquisition of data about Earth's surface from a satellite orbiting Earth or from other long-distance method. Create a photo of Earth's surface providing vital information.
The name given to a place on Earth. Example: The national capitol is named after George Washington.
The physical character of a place.
The location of a place relative to other places.
The scientific method of transferring locations on Earth's surface to a flat map.
A simplified abstraction of reality, structured to clarify casual relationships: to explain patterns, make informed decisions, and predict future behaviors.
The numbering system to which the location of each meridian is identified on Earth's surface.
An arc drawn between the North and South poles.
A circle drawn around the globe parallel to the equator and at right angles to the meridians.
The meridian that passes through the Royal Observatory at Greenwich, England at 0 degrees longitude.
The numbering system to indicate the location of a parallel.
0 degrees latitude.
North and South Poles
90 degrees North and South latitude.
International Date Line
An arc that for the most part follows 180 degrees longitude, although it deviates in several places to avoid dividing land areas. When crossed East, the clock moves back 24 hours. When crossed West the clock moves forward 24 hours.
Adjusts the size of a country corresponding to the magnitude of a mapped feature
Each dot represents some frequency.
Puts features into classes and maps classes of each region.
Connects points of equal value.
Map of an area in your mind.
A combination of cultural features such as language and religion, economic features such as agriculture and industry, and physical features such as climate and vegetation.
Formal Region/Uniform Region
An area within which everyone shares in common one or more distinctive characteristics.
Functional Region/Nodal Region
An area organized around a node or focal point.
Perpetual Region/Vernacular Region
A place that people believe exists as a part of their cultural identity.
A map that displays spatial distribution of an attribute that relates to a single topic, theme or subject of discourse.
A special type of map in which the variation in quantity in a factor such as rainfall, population, or crops in a geographic area is indicated.
How the physical environment caused social development.
The theory that the physical environment may set limits on human actions, but people have the ability to adjust to the physical environment and choose a course of action from many alternatives.
The total number of objects in and area, is commonly used to compare the distribution of population in different countries.
The number of persons per unit of area suitable for agriculture.
The geometric arrangement of distribution. (linear, centralized, or random)
The reduction in time it takes for something to reach another place.
The process by which a characteristic spreads across space from one place to another over time.
The place from which an innovation originates.
The spread of an idea through physical movement of people from one place to another.
The spread of a feature from one place to another in a snowballing process. Is the result from either Hierarchical Diffusion, Contagious Diffusion, of Stimulus Diffusion.
Spread of an idea from person or place of authority that results in Expansion Diffusion.
Diffusion of a characteristic through the population that results in Expansion Diffusion. i.e. swine flu.
The spread of an underlying principle even if the characteristic fails to diffuse.
Relatively far apart.
The trailing-off phenomenon
Features and patterns representing human occupation and use of natural resources.
Intersecting at right angles at uniform intervals to form square or rectangle blocks.
Friction of Distance
As the distance from a point increases, interactions within that point decrease usually because of time and cost involved with increase of distance.
The degree to which the nodes of a network are directly connected with each other.
The ability to reach a place with respect to another place.
A landscape unaffected by human activity.
A location of a place relative to another place.
A point on the earth's surface expressed by a coordinate system such as latitude and longitude.
The natural arrangements of animals and plants in particular regions or districts.
Approximate measurement of the physical space between two places.
Exact measurement of the physical space between two places.
Based on North, South, East, or West.
The direction of a place in relation to that of other places.
The succeeding stages of human inhabitation over time on one site.
One of more than 24 divisions of the earth, based on sections 7.5 degrees east and west of every 15 degree increment of longitude. There are 24 time zones (360 degrees divided by 15 degrees is 24) plus several offset time zones. Time zones allow the time to follow the rotation of the earth.
