QUESTIONS FOR QUIZ A: GEOG 360 You will note that most of these questions require short answers. There will not be much space on the quiz paper for each of your answers and you will not have much time in which to write your answers (about one minute per question) so I suggest that after reading the required materials you draft a clear but succinct answer to each question as practice. From Cartography: Thematic Map Design , Chapter 1: What is the difference between Qualitative and Quantitative Thematic maps ? Qualitative thematic maps provide spatial distributions of nominal data . This means that they do not use specific numbers in communicating with the map reader. An example of this would be a map illustrating land use in the United States. On the other hand, Quantitative maps use numerical data and to illustrate information such as population density, or voter turnout rates for example. What is Dent’s definition of a ‘Mental Map’ ? Mental maps are a form a maps constructed primarily by sensory perceptions in our own minds. As a result these maps will not be as accurate a representation of reality as the other types of maps. An example of this would be if someone would label various parts of New York based on approximations one personally makes. What are the components of a Thematic Map ? A base map, thematic overlay and a set of ancillary map elements . A base map provides the locational foundation for the entire illustration, while the thematic overlay incorporates the variables of interest, and the ancillary elements provide clarity in the form of titles or legends. What is meant by ‘map scale’ ? The amount of reductions that occur when going from real world sizes to the mapped area. This scale ranges from large to small. Large scale maps yield a lot of information, however, are zoomed in to a great extent (ex: a map of a specific county in the U.S.), while small scale maps provide more generalized information and sacrifice some information in doing things like not scaling cities (ex: entire US Map). Describe the ‘selection’ process of cartographic abstraction and generalization. The selection process regards early decisions made concerning elements of the map such as map scale and which geographic space is mapped. An example would be choosing to map the just one state within the United States.
