Unit 1 Flashcards
Mercator map projection
Accurate direction, distortion in size and location of the landmasses
Robinson projection
Puts majority of distortion at the poles, true size and shape of the landmasses
Reference map
Informational map that shows boundaries, names, etc.
Topographic map
Uses lines to display terrain and elevation changes
Absolute direction
The exact direction you are heading
Relative direction
The direction depends on the surrounding area
Absolute distance
The exact distance between 2 places (miles or km)
Relative distance
An approximate measurement between 2 places (time)
Absolute location
The exact spot where something is located
Relative location
A description of a location using surrounding geographic features
Thematic map
Displays spatial patterns of places and uses quantitative data
Every map projection has distortion in either…
Direction, shape, area, or distance
Toponym
A name given to a place or location
Choropleth map
Uses different colors
Dot density map
Show data by placing points on a map where data is occurring, see spatial distribution
Spatial analysis
Process of analyzing patterns and relationships within an area or geographic data
Clustered
Objects in an area close together with no space between them
Dispersed
Objects in an area are spread out with space between them
Graduated symbol map
Uses shapes (usually circles) to show location and amount of data
Isoline maps
Use lines to connect different areas that have similar equal amounts of data (weather map)
