Reference maps
Shows physical geography of a place. (ex: Boundaries, physical features, etc)
Thematic maps
Shows how phenomenon are distributed (ex: population, climate, etc.
Types of Thematic maps
Choropleth, Cartogram, Dot, graduated symbol and Isoline.
Choropleth
shading or coloring indicates different values.
Cartogram
distorted shape to show emphasis.
Dot
more of something=more dots
Graduated Symbol
Symbol’s size depends on how much there is
Isoline
Lines join all points that have same value

Description of location
Distance decay
The interaction between two things decrease as the distance between them increases.
Ex: Radio signals
Friction of Distance
when things are further apart, they tend to be less well connected
Environmental Determinism
Environment determines how and where humans will live.
Possibilism
Environment influences but humans find a way around
Scale
amount of detail
