CV3-2 - Basic concepts of symbolization

You are currently viewing an archived version of Topic Symbolization and the Visual Variables. If updates or revisions have been published you can find them at Symbolization and the Visual Variables.

Learning Objectives: 
  • List the variables used in the symbolization of map data for visual, tactile, haptic, auditory, and dynamic displays
  • Select effective symbols for map features based on the dimensionality and attributes of the geographic phenomena being mapped
  • Design map symbols with sufficient contrast to be distinguishable by typical users
  • Illustrate how a single geographic feature can be represented by various graphic primitives (e.g., land surface as a set of elevation points, as contour lines, as hypsometric layers or tints, and as a hillshaded surface)
  • Identify the visual variables (e.g., size, lightness, shape, hue) and graphic primitives (points, lines, areas) commonly used in maps to represent various geographic features at all attribute measurement levels (nominal, ordinal, interval, ratio)
