Unit 1: Thinking Geographically Flashcards
Reference Map
A map that emphasizes the location of a place without using data.
Thematic Map
A map that emphasizes the spacial patterns of places using data.
Absolute Distance
Describing distance in quantitative terms (miles, kilometers, etc.)
Relative Distance
Describing distance in qualitative terms (30 minutes south, etc)
Clustering
Items that are close together and concentrated into one area
Dispersal
Items are spread apart over a geographic space.
Mercator Projection
Distorts shape and size, but keeps distance.
Goode Homolosine Projection
A projection that minimizes distortion, but is interrupted (not an oval or sphere).
Fuller Projection
A projection that does not use cardinal directions, but has accurate shape and size.
Robinson Projection
A projection that spreads distortion out through size, shape, and direction.
Winkel Tripel Projection
A projection that is rounder in shape, but has distortion near the north and south poles.
Qualitative Data
Data that is opinion based such as polls and surveys.
Quantitative Data
Research that can be replicated such as census or marketing data.
GIS (Geographic Information System)
A geographic information system (GIS) is a computer system for capturing, storing, checking, and displaying data related to positions on Earth’s surface.
Scale
The ratio of a distance on a map to the actual distance on the ground.
