Chapter One Flashcards
Geography
Geo = Earth. Graphy = to write. The study of where things are found on Earth’s surface and the reasons for their locations.
Place
Specific point on Earth distinguished by a particular characteristic.
Region
An area of Earth defined by one or more distinctive characteristics.
Scale
The relationship between the portion of Earth being studied and Earth as a whole.
Space
The physical gap or interval between two objects.
Connection
Relationships among people and objects across the barrier of space. (rivers between bodies of water/bridges)
Map
Two-dimensional or flat scale model of Earth’s surface, or a portion of it.
Two purposes of a Map
- A reference tool to help us find shortest route between two places and avoid getting lost.
- Communications tool to depict the distribution of human activities or physical features and reasons underlying a distribution.
Cartography
The science of mapmaking (assisted by satellite imagery & computers)
Geographic Information Science (GI Science)
An analysis of data about Earth acquired through satellite & other electronic information technology.
Geographic Information System (GIS)
Captures, stores, queries, and displays the geographic data.
Photogrammetry
The science of taking measurements of Earth’s surface from photographs.
Remote Sensing
Acquisition of data about Earth’s surface from a satellite orbiting Earth or from other long-distance methods (airplanes, drone).
(GPS) Global Positioning System
System that determines the precise position of something on Earth.
Geotagging
Identification & storage of a piece of information by its precise latitude and longitude coordinates.
Volunteered geographic information (VGI)
Creation and dissemination of geographic data contributed voluntarily and for free.
Citizen Science
Scientific research by amateur scientists. Collect and disseminate local knowledge and info through electronic devices.
Participatory GIS (PGIS)
Community-based mapping. Collect and disseminate local knowledge and info through electronic devices.
Mashup
A map that overlays data from one source on top of a map provided by a mapping service (google maps/bing maps).
Mental Map
Personal representation of a portion of Earth’s surface. It depicts what an individual knows about a place and it contains personal impressions of what is in the place and where it’s located.
Map Scale
The relationship of a feature’s size on a map to its actual size on Earth. Presented in three ways: Ration, Written, Graphic.
Ratio (map scale)
Numerical relationship between distances on the map & Earth’s surface. Ex: ratio of 1:1,000,000 is one unit (inch, cm, ft) = 1 million of same unit on the ground.
Written (map scale)
Relationship between map & Earth’s distances in words. Ex: “1 centimeter equals 10 kilometers.”
Graphic (map scale)
A bar line marked to show distance on Earth’s surface. Ex: determine with ruler the distance on the map in inches or centimeters. Then, hold the ruler against the bar line and read the number on the bar line opposite the map distance on the ruler.
