hypsometric map



Hypsometric maps use different colors to represent the elevation of terrain on a land area- green meaning flat, reddish/brown meaning hilly/mountainous, and white at highest peak.

thematic map


"thematic map" meaning themed map, basically. Just a map with a specific purpose, used with various different map types. This one shows the Hispanic population by county in Texas shaded by colors.

A planimetric map shows only the horizontal positions of features (not the vertical positions; for example- heights, as in a topographic map).

This map shows the Washington DC area. Grey areas represent infrastructure, pink areas represent residential and business buildings, and in the right hand side Forestry GIS added in the vegetation areas in green.

windrose

A windrose plot is a circular graph with each spoke broken down into color-coded bands that show wind speed ranges. They also use cardinal directions to show what speed wind was in what direction.
This map shows winds average over the period September 11-13, 2001 for the NYC area (coming from the west).

scatterplot

A scatterplot uses points on, usually, a graph to explain it's coordinate.
This scatterplot I found actually shows two different views on the worlds population GDP per capita in US dollars. The 1 on the x-axis represents "jus solis" which means citizenship by birth and countries with birth rights. The 2 represents not a citizen by birth. Each point represents one country's average GDP per capita (for each column).

propaganda map

A propaganda map is used to "sway" the viewer to think one thing over another. A lot of propaganda maps are used politically.
This map uses plastic cups on a platform shaped like the US to describe the American obesity rate across the country. Each color inside the cup represents the area's obesity statistic. This map uses propaganda by shaping the McDonalds golden arches in the middle to show that McDonalds is partially to blame for America's obesity.
As I was researching more about this famous propaganda map, I found this: "Figures from 1994 are indicated on one side of the cups, and those from 2002 on the other, so that the extraordinary increase in obesity levels becomes dramatically apparent as viewers walk from left to right." I found that to be very interesting.

mental maps

I think mental maps are very eccentric. They can describe so many different things, places, emotions, etc. You don't necessarily need a legend, you can use your imagination or inner senses to describe the map. This map, for instance, is describing the layout of a park possibly in the middle of a city? Each picture represents a different area of the park. In the top right corner, there is most likely a skate ramp or a skateboarding area. There are probably statues in the central area and basketball hoops in the southeast corner.
