________: Instead of using a unit of measurement, it is based on an estimate.
Map
two-dimensional representation of an area of land or sea showing physical features, political features, roads, etc.
Weaknesses
________: Area, shape, size, and direction are all slightly distorted.
Reference maps
These maps provide basic information. There are four different types:
Political maps
Physical maps
Road maps
Plat maps
Thematic maps
These maps provide more specific information than reference maps. There are five different types:
Cartograms: A map in which the geometry of the regions are distorted according to specific statistics.
Choropleth: A map that uses different colors, shadings, or patterns to demonstrate data.
Isoline/Topographic: A map that uses lines that are drawn on a map connecting points of the same value.
Graduated symbol: A map that uses different symbols to show different amounts of sizes.
Dot distribution: A type of map that uses a symbol to demonstrate the geographic distribution.
Scale
ratio between the size of things in the real world compared to the size of those same things on the map
Strengths
________: Preserves shape and direction.
Cartographic scale
Refers to the way how the map compares the ratio of its size to the size of what it represents.
Geographic scale
Refers to the area of the world being studied.
Small scale map
show a larger amount of area with less detail.
Large scale map
show a smaller amount of area with greater amount of detail.
Absolute location
Exact location using latitudes and longitudes. Ex: Paris, France is located at 48.8566 degrees N, 2. 3522 degrees E.
Relative location
Not exact location, is used to describe location based on its relationship with another location. Ex: The Target is located right next to my house.

Absolute location
Exact location using latitudes and longitudes
Ex
Paris, France is located at 48.8566 degrees N, 2
Relative location
Not exact location, is used to describe location based on its relationship with another location
Ex
The Target is located right next to my house
Absolute direction
Exact direction using cardinal points
Ex
Target is southeast of Georgia.2
Relative direction
Not exact, is used to describe distance based on its relationship with another direction
Ex
Her house is right opposite of mine
Absolute distance
Uses a unit of measurement
Ex
Target is 15 miles away from Walmart.2
Relative distance
Instead of using a unit of measurement, it is based on an estimate
Ex
This is just around the corner
Purpose
This projection is mainly used for navigation purposes
Strengths
Preserves shape and direction
Weaknesses
Distorts size/land area
Purpose
This projection is mainly used for spatial distributions related to area
Strengths
Preserves size/land area
Weaknesses
Distorts shape
Purpose
This projection is used generally
Strengths
No major distortion
Absolute direction
Exact direction using cardinal points. Ex: Target is southeast of Georgia.
Relative direction
Not exact, is used to describe distance based on its relationship with another direction. Ex: Her house is right opposite of mine.
Absolute distance
Uses a unit of measurement. Ex: Target is 15 miles away from Walmart.
