1.09.03 Visual Variables

Fri, 10/26/2007 - 18:05
Planners and cartographers convey spatial geographic information through a visual language consisting of a combination of the following:
  1. symbols (points, polylines, and polygons),
  2. variables (hue, orientation, value, shape, size and texture), and
  3. interpretation keys.
The effectiveness of a map in communicating its intended purpose depends on the selection of features, the way these features are depicted, and the ability of the users to objectively understand and relate these features to their life situation. For instance, when a map is used to support active interaction among parties during the planning exercise, such as in the formulation of the CLUP Scenarios, it is important that the graphic vocabulary of the maps that have been prepared is fully understood by all parties and each feature is provided with a commonly defined key for interpretation (see Chapter 4.21.02 in the Toolbox).
