Reference Maps
Reference maps are designed for people to get specific information about places, typically natural features or the location of cities, towns, etc.
Thematic Maps
These maps describe different spatial patterns (clustered, dispersed, random) of attributes and statistics. The types of maps include, Isoline/Topographic, Cartograms, Choropleth, Dot Density, Graduated Symbol.
Chloropleth Map
A map that uses shading, coloring, or even symbols to represent different data values. For example population and unemployment rates.
Dot Density Map
A map that uses dots the density of dots to symbolize the number of features in an area.
Isoline Map
An isoline map uses lines to connect data of the same values.
Graduated Symbol Map
A map with symbols that vary in size according to the density of the feature they represent. Proportional symbol maps are another name for graduated as it’s used interchangeably.
Cartogram Map
Cartograms use color or distortion to represent different data values as well. The distortion separates itself from other maps.
Absolute Location
Exact location of the Earth using longitude and latitude.
Absolute Distance
The exact distance of 2 different places. Uses a determined unit of measurement. The distance can be determined using a scale.
Absolute Direction
Correlates to the direction of a compass. Combinations of North, East, South, and West
Relative Location
A description of how location is related to the places that are near it.
Relative Direction
Describes a place based off its direction.
Relative Distance
Measure of cultural, social, and economic connectivity between 2 places.
Elevation
The height above a certain level or to which something is raised.
Distortion
Altering the original shape of something.
