APHG

Map

A two dimensional (flat) representation of a geographic area or place.

Cartographer

A person who makes maps.

Data Aggregation

The process of collecting and organizing large amounts of information.

Spatial Perspective

A geographic perspective that seeks to identify and explain the uses of space.

Spatial Patterns

The placement or arrangement of objects on Earths surface; also includes the space between those objects.

Time-distance Decay

Also known as the "first law of geography"; the idea that near things are ore related than distant things, and interaction between two places decreases the farther apart they are

Map Symbols

Graphic elements that help organize the information in a map, such as (but not limited to) dots, stars, arrows, squares, and dotted lines.

Legend

A key to the meaning of the symbols and colors on a map

Compass Rose

A drawing, usually found on the edge of a map, showing the four cardinal directions (north, south, east, west) and the maps orientation.

Absolute Direction

Corresponds to the direction on a compass; north, south, east, west, and combinations such as northeast, southwest.

Map Scale

The distance on a map in relation to distance in actual space; for example, 1 inch on a map might indicate a distance of 100 miles

Scale

The territorial extent of an idea or object

Absolute Distance

The distance that can be measured with a standard unit of length, such as a foot, yard, mile, or kilometer.

Relative Distance

A measurement of the level of social, cultural, or economic similarity between places despite their absolute distance from each other.

Relative Direction

A direction that can be described as position, such as in front of or behind, to the left or to the right

Elevation

Distance above sea level

Isoline

On a map, a line that connects or links different places that share a common or equal value, such as elevation

Topographic Map

A graphic representation of the three-dimensional configuration of Earth's surface

Reference Map

A map that shows geographic locations on Earths surface, such as locations of cities or oceans

Thematic Map

A map that emphasizes the spatial patterns of geographic statistics or attributes, and sometimes the relationships between them

Choropleth Map

A thematic map that shows data aggregated for a specific geographic area, often using different colors to represent different values.

Cartogram

A map that distorts the geographic shape of an area in order to show the size of a specific variable; the larger the area on a cartogram, the larger the value of the underlying variable.

Proportional Map

Also known as graduated circle map; A map that uses symbols (such as circles or dots) of different sizes to represent numerical values.

Dot Density

Also known as dot distribution maps; A map that uses dots to represent objects or counts; the dot can represent one object ( a one to one dot density map) or it can represent a number of objects (a one to many dot density map)

Map projection

A method for representing the surface of Earth or a celestial sphere on a plane (two-dimensional) surface; all map projections distort some aspect of Earths surface.

Mercator Projection

A map projection that is useful for navigation because the lines connecting points on the map represent the true compass direction; however, landmasses become increasingly distorted the farther away they are from the equator.

Peters Projection

A map projection that shows all landmasses with their true areas but distorts their shapes.

Goode Homolosine Projections

A map projection that avoids shape distortion and the restrictions of a rectangular map by creating interruptions in the maps continuity; in each section, map projection regions are shown "equally", like an orange peel being laid out on a flat surface.

Polar Projection

A map projection that looks down at Earth from the perspective of one of the pole (north or south)

Robinson Projection

A map projection that attempts to create the most visually appealing representation of Earth by keeping all types of distortion relatively low over most of the map.

Census

An official count or survey of a population, typically recording various details about individuals, such as age, sex and race.

Fieldwork

Learning and doing research involving first-hand experience, which takes place outside the classroom setting.

Absolute Location

A precise position on Earths surface

Latitude (lines)

The (invisible) horizontal lines circling Earth parallel to the equator; latitude is the degree of distance north or south from the equator, which is at 0 degrees, as far as the poles, which are at 90 degrees.

Longitude (lines)

The (invisible) vertical lines on Earths surface that mark imaginary circles connecting the north pole with the south pole.

Prime Meridian

The zero-degree longitude line that runs through Greenwich, England; also known as the Greenwich Meridian

Global Positioning System (GPS)

A system of 24 satellites that orbit Earth twice daily and transmit radio signals Earthward; the basis for many map-based apps that provide directions on how to get for one place to another.

Geographic Information System (GIS)

A software application for capturing, storing, checking, and displaying data related to positions on Earths surface, allows the rapid manipulation of geospatial data for problem-solving and research.

Remote Sensing

The scanning of Earth by satellite or high-flying aircraft in order to obtain information about it.

Aerial Photography

Remote-sensing photography that produces fine-grained, high-solution, highly detailed images.

Satellite Imagery

Images of Earths surface gathered from sensors mounted on orbiting satellites; these sensors record in both the visible and non-visible portions of the electromagnetic spectrum, allowing humans to view patterns and processes that are both visible and invisible to the naked eye.

Relative Location

The position of one place (or person) in relation to the position of another place (or person)

Space

The areas we occupy as humans, it has no value until the people who occupy it make it their own.

Place

How we modify space based on who we are as a group of people.

Cultural Landscape

The built forms that cultural groups create in inhabiting Earth - farm fields, cities, house, etc. - and the meaning, values, representations, and experiences associated with those forms.

Time-Space Compression

The decreasing distance between places, as measured by travel time or cost; often summarized by the phrase "the world is shrinking"

Interdependence

The ties established between regions and countries that over time collectively create a global economic system that is not necessarily based on equality.

Geographic Processes

The physical and human forces that work together to form and transform the world

Diffusion

The pattern by which a phenomenon such as the movement of people, or their ideas, technologies, or preferences, spreads from a particular location through space and time.

Independent Invention

Occurs when the same or a very similar innovation is developed at the same time in different places by different people working independently.

Expansion Diffusion

Occurs when ideas or practices spread throughout a population, from area to area, in a snowballing process, so that the total number of knowers or users and the areas of occurrence increase.

Hierarchical Diffusion

Occurs when ideas leapfrog from one important person, community, or city to another, bypassing other persons, communities, or rural areas.

Reverse Hierarchical Diffusion

Occurs when ideas leapfrog from a lower level of a hierarchy to a higher level.

Contagious Diffusion

The wavelike spread of ideas in the manner of a contagious disease or forest fire, moving throughout space without regard for hierarchy.

Stimulus Diffusion

Occurs when a specific trait is rejected, but the underlying idea is accepted.

Relocation Diffusion

Occurs when individuals or groups with a particular idea or practice migrate from one location to another, thereby bringing the idea or practice to their new homeland.

Friction of distance

The inhibiting effect of distance on the intensity and volume of most forms of human interaction; time-space compression diminishes friction of distance.

Ecology

The global warming trend caused by rising levels of carbon dioxide (CO2)

Environmental Determinism

The belief that the physical environment is the dominant force shaping cultures and that humanity is a passive product of its physical surroundings.
