Propaganda Map: Cold War Mercator Projection



This map is a basic example of a propaganda map. These types of maps are used to shape opinion by manipulating the true phenomena. This is done by molding the maps' message by emphasizing supporting features while suppressing contradictory information. Basically, the message can be manipulated by the cartographer according to their own biases or need to convey a message. The above map is an example of how a Mercator projection map could have been used during the Cold War to show the perceived threat of communist nations of the Warsaw Pact. By using a Mercator projection, nations such as the USSR, can appear larger than they really are due to its high elevation. This would be an important tool to aid in propaganda as it makes the threat, at the time, appear larger than it really is. Also, the use of colors is important because the use of red to identify "enemies" promotes a sense of danger or menace.



Hypsometric Map: Las Bayas, Argentina (elevation)



Hypsometric maps are surface maps that show relief (Topography), and it is where three dimensional information is shown. This third dimension may represent relief or any other number of variables that describes a phenomena or process superimposed on the surface. This can be represented by color and shaping, contour lines, or raised relief. This map shows the elevation changes of Las Bayas, Argentina by use of both shaping and color. The lower areas are represented by green shades and then transfers to red shades at higher elevations.
