Learning Objectives: 
  • Describe a technique that can be used to represent the value of each of the components of data quality (positional and attribute accuracy, logical consistency, and completeness)
  • Apply multivariate and dynamic visualization methods to display uncertainty in data
  • Sketch a map with a reliability overlay using symbols suited to reliability representations
  • Develop graphic techniques that clearly show different forms of inexactness (e.g., existence uncertainty, boundary location uncertainty, attribute ambiguity, transitional boundary) of a given feature (e.g., a culture region)
