Anglocentric | Focused on the English culture. |
Azimuthal projection | Map that maintains direction but distorts other properties; flat-plane-constructed map of each hemisphere; direction is accurate , and great-circle routes are apparent. |
Cardinal Directions | North, south, east and west. |
Cartogram | Map that uses proportionality (i.e., space on the map) to show a particular variable. |
Cartography | Process of mapmaking |
Coropleth Thematic map | Map that shows a pattern of a variable, such as population density or voting patterns, by using various colors or degrees of shading. |
Cognetive (or mental) map | Map drawn from memory. |
Conformal (or orthomorphic) projection | Map that maintains shape but distorts other properties |
Cutural ecology | Study of human environmental interaction. |
Data aggregation | Size of geographic units being represented on a map. |
Distance decay | Pattern in which the interaction between two places declines as the distance between the two places increases. |

Dot density map | Thematic map that uses dots to represent the frequency of a variable in a given area. |
Equal-area (or equivalent) projection | Map that maintains area but distorts other properties. |
Equidisttant projection | Map that maintains distance but distorts other properties. |
Formal Region | Region composed of areas that have a common (or uniform) cultural or physical feature, sometimes referred to as uniform regions. |
Four main properties of a map | Shape, size, distance and direction. Shape refers to the geometric shapes of the objects on the map. Size refers to the relative amount of space taken up on the map by the landforms or objects on the map. Direction refers to the degree of accuracy |
Friction of distance | Degree to which distance interferes with some interaction. |
Functional region | Group of places linked together by some function's influence on them after diffusing from a central node; sometimes referred to as a nodal region. |
Geographic information system | Computer program that stores geographic data and produces maps that show the data. |
Geographic model | Simplified version of what exists on the earth or what might exist in the future; helps a geographer search for answers to why patterns exist on the earth as they do. |
Global positioning system (GPS) | System of satellites used to determine an exact location on the global grid. |
Great circles | Circles formed on the surface of the earth by a plane that passes through the center of the earth. The equator and every line of longitude paired with its twin on the opposite side of the earth from great circles. Any arc of a great circle - shorest dista |
Greenwich mean time (GMT) | Baseline for time zones around the world, centered on the prime meridian; sometimes called Universal time. |
Human-environment interaction | One theme of geography through which geographers analyze humans' impact on their environment and their environment's impact on them. |
Human geography | Branch of geography primarily concerned with analyzing the structures, processes, and location of human creations and interations with the earth. |
Intermediate directions | Northwest, southwest, northeast, and southeast. |
Isoline thematic map | Map displaying lines that connect points of equal value; for example, a map showing elevation levels. |
Lines of latitude | Measured in degrees north & south from the equator, which is 0 degrees latitude. The North Pole is 90 degrees north latitude & the South Pole is 90 degrees south latitude. Lines of latitude never intersect, geographers often call lines of latitude parall |
Lines of longitude | Measured in degrees east & west of one line of longitude know as the prime meridian, the line of longitude that runs through England's Greenwich Observatory. The prime meridian represents 0 degrees longitude. |
Map | Two dimensional model of the earth or a portion of its surface. |
Map (or cartographic) scale | Map showing the shapes of the continents and landforms accurately but drastically distorting the size (area) of the continents. For example, Greenland appears almost as large as Africa. |
Movement | Theme in geography involving the movement occurring in a space; movement of information, people, goods, and other phenomena. |
Node | Place from which a diffusing phenomenon spreads to other places (its originating point). |
Perceptual (or vernacular) region | Region whose boundaries are determined by people's beliefs, not a scientifically measurable process. |
Gall-Peters projection | Map created by a geographer to show the relative sizes of the earth's continents accurately (equal area). However, it distorts shape, so it is not conformal. |
Physical geography | Branch of geography concerned with spatial analysis of the structures, processes, and locations of the earth's natural phonomena, like soil, climate, plants, and topography. |
Place | Theme is geography that involves the unique combination of physical and cultural attributes that give each location on the earth its individual "stamp". |
Primary data | Data directly collected by the geographer making the map or conducting the study. |
Proportional-symbol thematic map | Map that uses some symbol to display the frequency of a variable. The larger the symbol on the map, the higher the frequency of the variable found in that region. |
Reference Map | Map showing common features like boundaries, roads, highways, mountains and cities. |
Region | Theme in geography involving spatial unit that has many places sharing similar characteristics. |
Relative directions | Directions commonly given by people, such as right, left, up, and down, among many others. |
Remote sensing | Technique of obtaining information about objects through the study of data collected by special instruments that are not in physical contact with the objects being analyzed. |
Robinson projection | Map showing the world with slight distortion to all four properties, rather than having one property correct and the other three drastically distorted. |
Secondary data | Data used by a geographer but collected by another source that previously conducted a study and made the data available for future use. |
Sense of place | Person's perception of the human and physical attributes of a location that give it a unique identity in that person's mind. |
Simplification | Cartographer's process of eliminating unneccesary details details and focusing on the information that neesd to be displayed in the map. |
Site | Internal physical and cultural characteristics of a place, such as its terrain and dominant religions, among others. |
Situation | Location (or context) of a place relative to the physical and cultural characteristics around it. THe more interconnected a place is to other powerful places, the better its situation. |
Space-time compression | Increasing sense of accessibility and connectivity that seems to be bringing humans in distant places closer together. |
Spatial perspective | Outlook through which geographers identify, explain, and predict the human and physical patterns in space and the interconnectedness of different spaces. |
Thematic map | Map that zeros in on one feature such as climate, populatiion, or voting patterns. |
