FC-23 - Scale and generalization

Learning Objectives: 
  • Differentiate among the concepts of scale (as in map scale), support, scope, and resolution
  • Discuss the implications of tradeoff between data detail and data volume
  • Select a level of data detail and accuracy appropriate for a particular application (e.g., viewshed analysis, continental land cover change)
  • Defend or refute the statement “GIS data are scaleless”
  • Determine the mathematical relationships among scale, scope, and resolution, including Töpfer’s radical law
