Map Critique

    For this week's lesson, we were tasked with finding, selecting, and critiquing two maps- one as an example of a "good map" and one as an example of a "bad map". We had to justify our critique by discussing the various map principles and how each map executed the various "Tufteisms". We evaluated each map's use of cartographic design in its attempt to convey substance in an aesthetically pleasing and logical way.

Example of a "Good Map"

    For my example of a good map, I chose a cartogram from ESRI's showcase gallery. It is not a traditional map but it uses a cartogram to depict the quantity and density of breweries in countries across the world. It uses simple symbology to quickly convey data; the audience can quickly decipher where the largest quantity of breweries are located through the use of size and color. Further information is provided in smaller subtitles and subtext, which is also color-coded. The cartogram symbols use beer caps, water stains, and a wooden tabletop commonly found in bars to reinforce the thematic message. The map title graphically reinforces the theme as well. Author, source credits, and map purpose and method are provided in the bottom right corner. Traditional map elements such as scale, scale units, and North arrow are not included due to the thematic (versus reference) nature of the map. It has a very casual feel, which is suitable for its audience. It quickly grabs the attention of readers and conveys information succinctly. This cartogram is most likely for entertainment than for scholarly information.

Example of a (hilariously) "Bad Map"

    The map I chose as an example of poor design is a choropleth created by EDM.com. This map attempts to elucidate the most popular electronic dance music (EDM) single by states within the continental United States. At first glance, the map looks aesthetically pleasing with its title clearly top and centered, a legible legend, and pretty shades of blues. However, it quickly becomes apparent that it is impossible to actually glean any information from this map. The colors chosen are too similar and have no detectable symbology. We, as the audience, have no way to access the information being presented. The map is missing additional key elements of effective design. The map is missing a timeframe, which is an important element when discussing the popularity of music. It also lacks an author's credit, statement of purpose, or methodology. It never explains what genre of music is being discussed or if there is any importance to the data presented.
