Unit 1 Flashcards
Relative to a fixed from of reference and always point in the same direction, regardless of their location
North/south and East/West are examples of this
Absolute Direction
The spatial separation between two points on the earth’s surface measured by some accepted standard unit such as miles of kilometers
Absolute Distance
A description of the exact site on an objective coordinate system, such as a grid
When referring to a map or the Earth’s surface, it is the latitude or longitude of a specific place
AKA - mathematical location
Absolute Location
The science or practice of drawing maps
Cartography
Extent of a feature’s spread over space
Clustered/agglomerated - close together
Dispersed/scattered - relatively far apart
Concentration
Relationships among people and objects across the barriers of space
Connection
The degree of direct linkage between one particular location and other locations in a transport network
Connectivity
Study of human adaptations to social and physical environments
Cultural Ecology
A long wall or embankment built to prevent flooding from the sea
Dike
Diminishing importance and eventual disappearance of a phenomenon as distance from origin increases
Distance Decay
Arrangement of a feature in space
Distribution
Distance above sea level
Elevation
Belief that the environment, most notably its physical factors such as landforms and climate, determines the patterns of human culture and societal development
Environmental Determinism
Increase in time and cost that usually comes with increasing distance
Friction of Distance
A way to understand a topic or area using spatial features and relationships
Geographic Perspective
Information about physical objects that can be represented by numerical values in geographical coordinates system; often gathered through census or satellite data collection
Geospatial Data
A computer system that can capture, store, analyze and display geographic data
Allows for complex maps with many layers (borders, water, roads, place names), resulting in mash-up maps that are useful for real estate and other applications
GIS
Geographic Information System
The process by which businesses or other organizations develop international influence or start operating on an international scale
Globalization
System that utilizes a satellite navigation system to provide location information anywhere on Earth with precise numerical coordinates
Commonly used to determine an individual’s exact location on Earth
GPS
Global Positioning System
The mean time of the meridian of Greenwich used historically as the prime basis of standard time throughout the world
Greenwich Mean Time
Interactions between the human social system and the ecosystem
Human-environment interaction
Study of where human activities are located and why
Human Geography
An imaginary line running north and south through the Pacific Ocean, largely along the 180th meridian
There is a 24-hr time difference between a point just west and one just east of the line, so that when it is Sunday just west of the line, it is Saturday just east of it
International Date Line
2-dimensional or flat-scale model of Earth’s surface or a portion of it
Map
Inaccuracies created when the round Earth is represented on a flat surface
These include shape, distance, relative size, direction
Map Distortions
Representation of round Earth on a flat surface
Map Projection
Type of map projection introduced in 1569 by Gerardus Mercator;
often described as a cylindrical projection, meridians are equally spaced parallel vertical lines, and the parallels of latitude are parallel horizontal straight lines that are spaced farther and farther apart as their distance from the Equator increases;
widely used for navigation charts, because any straight line on a Mercator projection map is a line of constant true bearing that enables a navigator to plot a straight-line course;
less practical for world maps because it drastically distorts relative size
Mercator Projection
Drawn to show Arctic and Antarctic areas; based on a plane perpendicular to the Earth’s axis in contact with the North or South Pole; limited to 10 or 15 degrees from the poles; provides true scale in polar regions, which are often the most heavily distorted in other types of map projections
Polar Projection
Compromise projection with the primary purpose of creating a visually appealing map of the entire world; does not eliminate any type of distortion, but it keeps the levels of all types of distortion relatively low over most of the map
Robinson Projection
