  • [CV-06-023] Map Analysis

    Map analysis is commonly listed as one of three aspects of user interaction with a map, along with map reading and map interpretation.  Map reading is generally categorized as using the basic functions of the map – matching symbols to the legend, using the scale and directional indicator, and so forth (Buckley & Kimerling, 2021; Tyner, 2015).  Map interpretation is typically considered to be a complex exploration of the data in the map, often with reference to other maps or data sources, to understand and explain patterns (Kimerling et al., 2016; Kraak & Ormeling, 2010; Tyner, 2015).  Map analysis lies somewhere in the middle, defined variously by scholars (Field, 2018; Kimerling et al., 2016; Tyner, 2015), but essentially a description, whether general or precise, of what’s in the map.  Analysis utilizes the basic tools of map reading to describe patterns or calculate characteristics, and questioning the assumptions and biases that may have influenced the map’s creation.  Map analysis is sometimes conflated with map critique, but a full analysis moves beyond critique to a larger assessment of the map’s messaging.
