Chapter 1 vocabulary Flashcards
geography
the study of where things are found on Earth’s surface and the reasons for the locations
map
a two-dimensional, or flat, representation of Earth’s surface or a portion of it
cartography
the science of map making
model
a simplified abstraction of reality, structured to clarify casual relationships; used by geographers to explain patterns, make informed decisions, and/or predict future behaviors
map scale
the relationship between the size of an object on a map and the size of the actual feature on Earth’s surface
projection
a system used to transfer locations from Earth’s surface to a flat map
Robinson Projection
useful for displaying information across the ocean
Mercator Projection
used to show directions to any location
distortion
misrepresentation of the area, size, and/or shape of a place on earth (typically land masses) resulting in the attempt to represent the round world/globe on a flat map
meridian
an arc drawn on a map between the North and South poles
longitude
the numbering system used to indicate the location of meridians drawn on a globe and measuring distance east to west of the prime meridian
prime meridian
the meridian, designated as 0 degrees longitude, that passes through the Royal Observatory at Greenwich, England
parallel
a circle drawn around the globe parallel to the equator and at right angles to the meridians
latitude
the numbering system used to indicate the location of parallels drawn on a globe and measuring distance north and south of the equator
equator
imaginary circle (line) that lies exactly halfway between North/South at 0 degrees latitude
absolute location
use of a coordinate system to have precise plotting for a location on Earth’s surface; can include the idea of formalized addresses
relative location
description of a place’s location based upon its locational relationship to other human and/or physical features
time zones
an area with an established standard time
Greenwich Mean Time (GMT)
the time in the zone encompassing the prime meridian, or 0 degrees longitude
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
geographic information science
the development and analysis of data about Earth acquired through satellite and other electronic information technologies
remote sensing
the acquisition of data about Earth’s surface from a satellite orbiting the planet or from other long-distance methods
global positioning systems (GPS)
a system that determines the precise position of something on Earth through a series of satellites, tracking stations, and receivers
global information systems (GIS)
a computer system that stores, organizes, analyzes, and displays geographic data
mashup
a map that overlays data from one source on top of a map provided by a mapping service
place
a specific point on Earth, distinguished by a particular characteristic
location
the position of anything on Earth’s surface
