Sequent OccupancyThe succession of groups and cultural influences throughout a place’s history.
Place-SpecificSeveral different historical layers contribute to culture, society, local politics, and economy of a specific place.
ScaleThe relationship of an object or place to the Earth as a whole.
Map ScaleDescribes the ratio of distance on map and the distance in the real world on absolute terms.
Relative Scale (scale of analysis)Describes the level of aggregation.
Level of AggregationThe level at which you group things together for examination.
Formal RegionAn area of bounded space that possesses some homogeneous characteristic or uniformity.
Functional RegionAreas that have a central place or node that is the focus or point of orign that expresses some practical. purpose
Vernacular RegionBased upon the perception or collective mental map of the region’s residents.
Homogenous CharacteristicThis means that across the region there is at least one thing that is the same everywhere within the regional boundary.
UniformityThe state of being the same or homogeneous.
Linguistic RegionWhere everyone speaks the same language but groups in that region can be very different culturally.
Regional BoundariesDiffer based upon the type of region.
Culture RegionsTend to have fuzzy borders.
Political RegionsFinite and well-defined.
Enviormental RegionsTransitional and measurable.
Bio-regions (biomes)A region defined by characteristics of the natural environment rather than by man-made divisions.
EcotoneThe environmental zone between two bio-regions.
Nodal Regions (a.k.a. Functional Regions)Areas that have central place or node that is a focus or point of origin that expresses some practical purpose.
Central Place (node)A focus or point of origin.
Market AreaA type of functional region.
Distance DecayThe farther away different places are from a place of origin, the less likely interaction will be with the original place.
Area of InfluenceHow far a place influences it surroundings, like how people come from longer distances but make a smaller number of trips.
Intervening OpportunityAn attraction at a shorter distance that takes precedence over an attraction that is farther away.
Mental MapThe cognitive image of landscape in the human mind.
Absolute LocationDefines a point or place on the map using coordinates such as latitude and longitude; latitude is given first followed by longitude with a cardinal direction, seperated by a comma.
Relative LocationRefers to the location of a place compared to a known place or geographic feature.
LatitudeMeasures distance, in degrees, north or south of the equator.
LongitudeMeasures distance, in degrees, east or west of the Prime Meridian.
NotationThe act of noting, marking, or setting down in writing.

SiteRefers to the physical characteristics of a place.
SituationRefers to the place’s inter-relatedness.
DistanceMeasured absolutely, or it can be measured relatively in terms of the degree of interaction between places or in units of time traveled.
Absolute DistanceDistance between two places as measured in linear units such as miles or kilometers.
Relative DistanceThe amount of social, cultural, or economic connectivity between places.
Distance DecayThe farther away different places are from a place of origin, the less likely interaction will be with the original place.
Tobler’s lawStates that all places are interrelated, but closer places are more related that farther ones.
Friction of DistanceWhen the length of distance becomes a factor that inhibits the interaction between two points.
Space-Time CompressionDecreased time and relative distance between places.
Modes of Transportation(i.e. airplanes) Reduce time travel between two distant points, and as a result, increase interaction.
Central PlacesCan be thought of as any node of human activity and are most often the centers of economic exchange.
Transportation NodesMarkets are often located here; also provides accessibility to and from these points; tend to be centrally located within the larger economic region.
Central Place TheoryProposed by Walter Christaller that explains how and where central places in the urban hierarchy should be functionally and spatially distributed with respect to one another.
Core and PeripheryMany different regional, cultural, economic, political, and environmental phenomena and human activities display some sort of this relationship.
Central Buisness District (CBD)The core of the urban landscape.
ClusterWhen things are grouped together on the earth’s surface.
Growth PoleRefers to a grouping of firms or an industry that generates expansion in an economy.
AgglomerationWhen clustering occurs purposefully around a central point or an economic growth pole.
Random PatternWhen there is no rhyme or reason to the distribution of a spatial phenomenon.
Scattered PatternObjects that are normally ordered but appear dispersed.
Linear PatternA pattern that appears in a straight line.
Sinuous PatternA pattern that appears as a wavy line (i.e. like the pattern of heartbeats on an EKG).
Land Survey PatternsHave an effect on the property lines and political boundaries of states and provinces.
Metes and Bounds Survey PatternThe use of natural landscape features (i.e. tree stumps, rocks, etc.) to divide land; East of central Ohio and Ontario, used until 1830s, but developed in Europe centuries earlier.
Township and Range Survey PatternSurvey system based upon lines of latitude and longitude; after the 1830s, when new techniques to accurately determine longitude were transferred from sea navigation to land survey, surveyors in the United States and Canada used this rectilinear survey system.
Long-Lot Survey PatternThese have a narrow frontage along a road or waterway with a very long lot shape behind; former French colonial areas such as Quebec and Louisiana have these survey systems.
Arithmetic DensityThe concept of density calculated by the number of things per square unit of distance.
Agricultural DensityRefers to the number of people per square unit of land actively used for farming.
Physiologic DensityMeasures the number of people per square unit of arable land, meaning both the land that is farmed and the land that has the potential to be farmed but is not active.
Malthusian TheoryThe idea that population is growing faster than the food supply needed to sustain it.
Diffusion PatternsThe multiple different ways and patterns in which human phenomena diffuse spatially or spread across the Earth’s surface.
HearthPoint of origin or place of innovation.
Hiearchical DiffusionThe pattern originates in a first-order location then moves down to second-order locations and from each of these to subordinate locations at increasingly local scales.
Contagious DiffusionThe pattern begins at a point of origin and then moves outward to nearby locations, especially those on adjoining transportation lines. This could be used to describe a disease but can also describe the movement of other things, such as the news in rural regions.
Stimulus DiffusionA general or underlying principle diffuses and then stimulates the creation of new products or ideas. For example, it occurs when vegetarian eating habits (principle) influence restaurants to offer more vegetarian dishes (new products).
Expansion DiffusionThe pattern originates in a central place and then expands in all directions to other locations. Note that the distance does not have to be equal in all directions.
Relocation DiffusionThe pattern begins at a point of origin and then crosses a significant physical barrier, such as an ocean, mountain range, or desert, then relocates on the other side. Often the journey can influence and modify the items being diffused.
Topographic MapsShows the contour lines of elevation as well as the urban and vegetation surface with road, building, river, and other natural landscape features. These maps are highly accurate in terms of location and topography. They are used for engineering surveys and land navigation, especially in wilderness regions.
Thematic MapsA number of different map types can be grouped under this heading, and that each one expresses a particular subject and does not show land forms for other features (i.e. Dot Density Maps; Isotherms).
IsothermsA weather map that shows temperature contour lines.
Chloropleth MapsExpresses the geographic variability of a particular theme using color variations. These variations can be expressed using colorized symbols, contour areas filled with different colors, or polygons denoting country boundaries filled with different colors to express the variability in the map.
Isoline MapsCalculates data values between points across a variable surface. Each point is then interpolated with the other nearby or neighboring points to create a continuous surface of isoline contours.
Dot Density MapsUses dots to express the volume and density of a particular geographic feature. The dots can represent the number of people in an area , or can express the number of events or phenomena that occurred in an area.
Flow-Line MapsUses lines of varying thickness to show the direction and volume of a particular geographic movement pattern (i.e. map of flow-lines showing the total number of foreign immigrants in the US).
CartogramsUses simplified geometries to represent real-world places. Political boundaries become polygons, and linear features such as roads become lines with basic angles often at 90 degrees and 135 degrees. More about the data being expressed than they are about landscape.
ProjectionsMethods of mapping Earth on a flat surface.
Equal-Area ProjectionsAttempt to maintain the relative spatial science and the areas on the map; however, these can distort the actual shape of polygons.
Lambert ProjectionBends and squishes the northern Canadian border islands to keep them at the same map scale as southern Canada on a flat sheet of paper.
Conformal ProjectionsAttempt to maintain the shape of polygons on the map, but also cause the distortion of the relative area from one part of the map to the other.
DistortionA change in the shape, size, or position of a place when it is shown on a map.
Mercator ProjectionAttempt to maintain the shapes of areas on the map, but often get the size wrong (i.e. the shape of Greenland is preserved, but it appears to be much larger than South America, when in reality it is much smaller).
Robinson ProjectionProjection that attempts to balance several possible projection errors.
Goode’s Homolosine ProjectionA pseudo-cylindrical, equal-area, composite map projection used for world maps.
ModelAn abstract generalization of real-world geographies that share a common pattern.
Spatial ModelAttempt to show the commonalities in pattern among similar landscapes.
Urban ModelShow how different cities have similar spatial relationships and economic or social structures.
Non-Spatial ModelModel that do not necessarily relate specific spaces, but rather other factors.
Demographic Transition ModelUses population data to construct a general model of the dynamic growth in national scale populations without reference to space.
Epidemiological Transition ModelDescribes changing patterns of population age distributions, mortality, fertility, life expectancy, and causes of death.
Concentric Zone ModelCreated in 1923 by theorist Ernest Burgess and represents the Anglo-America city of the United States and Canada during the height of industrialization; can be modified to create a graph showing the cost to distance relationship in urban real estate prices.
Bid-Rent CurveExplains why land prices are relatively low in suburban areas, but exponentially higher in the central business district (CBD).
Gravity ModelA mathematical model that is used in a number of different types of spatial analysis. Used to calculate transportation flow between two points, determine the area of influence of a city’s businesses, and estimate the flow of migration to a particular place.
Geographic Information Systems (GIS)Incorporate one or more data layers in a computer program capable of spatial analysis and mapping.
Data LayersNumerical, coded, or textual data that is attributed to specific geographic coordinates or areas.
Spatial AnalysisLooking at data to determine how phenomena relate together in space.
Global Positioning System (GPS)Utilizes a worldwide network of satellites, which emit a measurable radio signal.
Navstar SatellitesNetwork of U.S. satellites that provide GPS services.
Aerial PhotographyImages of Earth from an aircraft, printed on film, but digital camera usage is on the increase
Satellite-Based Remote SensingA computerized scanner to record data from the Earth’s surface. These data include not only visual light wavelengths, but also infrared and radar information.
