Unit 1: Basic Concepts Flashcards
Cartography
The science of mapmaking; cartographer backpack is used for indoor mapping.
Map Scale
Refers to the relationship of the feature's size on the map to its actual size and earth; alters the level of detail and the amount of area covered on a map Presented in 3 ways: 1. Ratio/fraction 2. Written scale 3. Graphic scale
Global Positioning System (GPS)
A system that determines the precise position of something on earth through series of satellites, tracking stations, and receivers
Geographic Information System (GIS)
A computer system the stores, organizes, analyzes, and displays geographic data.
Remote Sensing
The acquisition of data about earth’s surface from a satellite orbiting the planet or from other long-distance methods
Geographic Information Science (GIScience)
The development and analysis of data about Earth acquired through satellite and other electronic information technologies
International Date Line
An arc that for the most part follows 180° longitude, although it deviates in several places to avoid dividing land areas. The clock moves backwards 24 hours from passing it heading east. When crossing it heading west, the calendar moves forward one whole day.
Greenwich Mean Time (GMT)
The time in the zone encompassing the prime meridian or 0° longitude.
Latitude
The numbering system used to indicate the location of parallels drawn on a globe and measuring distance north and south of the equator
Parallel
A circle drawn around the globe parallel to the equator and at right angles to the meridians
Prime Meridian
The Meridian, designated as 0° longitude, that passes through the Royal Observatory at Greenwich, England
Longitude
The numbering system used indicate the location of meridians drawn on a globe and measuring distance east and west of the prime meridian
Meridian
An arc drawn between the north and south poles
Projection (and distortion)
The scientific method of transferring locations earth surface to a flat map. 4 types of distortion: 1. Shape 2. Distance 3. Relative size 4. Direction
Place
A specific point in earth distinguished by a particular characteristic
Location
The position of anything on earths surface
Toponym
The name given to a portion of earths surface
Site
Physical character of a place
