Graphic Detail
Geographic Information Systems (GIS) organize and clarify the patterns of human
activities on the Earth’s surface and their interaction with each other. GIS data, in the
form of maps, can quickly and powerfully convey relationships to policymakers and the
public. This department of Cityscape includes maps that convey important housing or
community development policy issues or solutions. If you have made such a map and
are willing to share it in a future issue of Cityscape, please contact rwilson@umbc.edu.
Micromaps display multiple maps on the same exhibit, with different geographic units highlighted in each map. A comparative micromap is a type of micromap with a series of indexed maps designed to convey change in a statistic. Mast (2014) previously introduced Cityscape readers to comparative micromaps. A two-way comparative micromap (hereafter, referred to as a TWCM; for examples, see Carr and Pickle, 2010) conveys change in a statistic in two dimensions; one dimension is typically time.
