Reference Maps
Made for people to refer to them about general info for places.
KEYWORD: Reference
Ex: Google maps, world maps
Isoline Maps
Also called isometric maps, they use lines that connect to points of equal value to show variations in data across space.
KEYWORD: Isoline -> Line
Ex: Topograph
Thematic Maps
Shows the spatial aspects of information or phenomena.
KEYWORD: Thematic -> Theme
Ex: Wheather maps, mind maps
Dot Distribution Maps
Used to show specific location and distribution of something. Each dot is a specific quantity.
KEYWORD: Dot & Distrabution
Ex: Each dot on a city map is a pet owner.
Choropleth Maps
Recognizable areas shaded or patterned in proportion with the measurement of the variable.
KEYWORD: Chloro -> Color
Ex: Republican Vs. Democrat political map
Graduated Symbol Maps
Displays symbols that change in size according to the value of the variable.
KEYWORD : Symbol
Ex: Hiroshima and Nagasaki impact map.
Cartogram Map
The size of a country or state is proportional to the value of the variable.
Ex: Canada is smaller because of the smaller population (variable).
Spatial Patterns
The general arrangement of things being studied.
KEYWORD: Spatial -> Space
Ex: Describing networks and relationships.
Absolute Distance
Measured in units (miles, kilometers).
KEYWORD: Aboslute
Ex: the elevation of Mt. Everest is over 2900 feet.
Relative Distance
The degree of nearness is based on time or money. Dependent on travel mode.
KEYWORD: Relative
Ex: My house is a 10-minute walk from my school.
Relative Direction
In relation to the subject’s current orientation and location.
KEYWORD: Relative
Ex: Left of Portugal and right of France.
Absolute Direction
Set to a fixed frame of reference. Always the same direction regardless of location.
KEYWORD: Absolute
Ex: N, W, E. S, below, above, right, left
Clustering
Also called agglomerated, it is to be in a group/concentrated area
KEYWORD: Cluster
Ex: Clustering of cities along the TX and MX border.
Dispersal
Spread over a large area.

Maps (General info)
- All maps are distorted in some way (spatial relationships, shape, area, distance, direction, ect.)
- All maps are selective in info
Projection
Scientific way of transferring locations of Earth onto a flat surface.
Ex: Maps
Scale
The relationship of a feature’s size on a map to its actual size on Earth.

Robinson Map
General use
KEYWORD: Robinson -> Baseball player -> Round ball
Ex: Oval shape, slight distortion all around,
Mercator Map
Navigation
Ex: Directions are accurate, lines or longitude and latitude meet at correct points, Distance between longitude and latitude seems equal, and land masses near the poles are accentuated.
Gall-Peter’s Map
Spatial distributions related to area.
KEYWORD: Peter
Ex: Sizes and masses are accurate, stretched, and shapes inaccurate, especially near the poles.
Conic Map
General use for mid-latitude areas
KEYWORD: Conic -> Cone
Ex: Arch/full circle, lines of longitude and latitude coverage, Lines of latitude are curved, size and shape are close to real life, Directions not constant, On other maps, longitude lines converge only at the poles.
Winkel Map
Used for World maps
Ex: Lattitude is slightly inaccurate, minimizes all distortion,
Data (General)
- May be collected from an organization/individual
- Used for various scales and government decisions
