Lesson 1, Chapter 1: Maps Flashcards
Understand the lesson
spatial patterns
where things are located in a space
what is a map used for?
used to analyze spatial patterns
absolute distance
the distance between one place and another (can be measured in units)
relative distance
a measure of social, cultural, or political differences/similarities between 2 locations
Describe the absolute distance and relative distance of Russia and Finland.
their absolute distance is very small (they are close); however, their relative distance is large when considering their policies, language, and culture
absolute direction
cardinal directions
relative direction
rather than mentioning cardinal directions, people say that they are going up/down or right/left
cluster
compact, close together
dispersal
more spaced out
elevation
height relative to sea level (most of the time represented by isoline map)
scale
how the distance on a map relates to the real world (ex. 1 in = 1000 mi)
large scale map
very detailed (ex. London city map)
small scale map
not as detailed (ex. the world map)
on maps, the directions are often depicted by…
a compass rose
Reference maps
map that displays specific geographic LOCATIONS
thematic maps
maps that display geography themes/information
Chloropleth map
data with different colors (ex. election maps)
dot distribution
uses dots to visualize the location of certain data points
what does one-to-one mean with regard to dot distribution graphs?
one dot = one unit of data
what does one-to-many mean with regard to dot distribution graphs?
one dot = a group of data
Graduated symbol map
uses symbols to represent data (e.g. population; there would be big shapes around populated countries and smaller shapes around less populated countries)
Isoline maps; what does it mean when the lines are closer together or further apart?; describe topographic maps
uses lines to depict data; closer lines represents rapid changes in data; lines further apart represent smaller changes in data; (most common ex. of isoline maps are topographic maps which represent changes in elevation; closer = more steep; further = gradual slope)
cartogram
distorts the size of geographic shapes to display differences in data
True or false: every two-dimensional map that exists is distorted in some way
True
