1. Maps And Scales Flashcards
Reference Maps
-show locations of places and geographic features.
•Absolute Location
(absolute locations do not change)
Thematic Maps
-tell a story about the degree of an attribute, the pattern of its distribution, or its movement
• Relative Location
(relative locations are modified and change over time)
(Thematic Map)
Graduated Circle
- represents quantity of the theme.
- have some inaccuracies
(Thematic Map)
Dot Maps
- represent the theme (population)
- easier to understand, but have their limitations
Isopleth Maps
- use lines to get averages for an area
- show the area where the most people are (actual distribution).
Choropleth Maps
- shade areas to represent numerical data by the intensity of the colour
- takes pre-determined areas and then shades in the province/entire area based on that average. You lose the differences (can’t tell the most populated areas).
Choropleth or Isopleth
- predetermined areas are completely coloured in, then it’s choropleth.
- lines to separate, and only some are shaded in then it’s a isopleth.
Cartogram
maps with areas scaled to show some other value than shear size.
Absolute Direction
non-culture bound, based on the cardinal points.
ex) Saskatoon is northwest of Winnipeg and Southeast of Edmonton.
Relative Direction
culturally dependent and vary by location.
ex) Does Winnipeg truly belong in the west or is it something else?
Absolute Distance
absolute spatial separation between two places.
ex) 400km
Relative Distance
non-absolute measurements of separation between places. ex) eight hours from Winnipeg to Saskatoon.
Mental Maps
maps we carry in our minds of places we have been and places we have heard of.
Activity Spaces
the places we travel to routinely in our rounds of daily activity
Geographic Information System (GIS)
a collection of computer hardware and software that permits storage and analysis of layers of spatial data.
