FC-23 - Scale and generalization
  • 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)

CV-04 - Scale and Generalization
  • Explain why the reduction of map scale sometimes results in the need for mapped features to be reduced in size and moved
  • Identify mapping tasks that require each of the following: smoothing, aggregation, simplification, and displacement
  • Illustrate specific examples of feature elimination and simplification suited to mapping at smaller scales
  • Apply appropriate selection criteria to change the display of map data to a smaller scale
  • Discuss the limitations of current technological approaches to generalization for mapping purposes
  • Explain how generalization of one data theme can and must be reflected across multiple themes (e.g., if the river moves, the boundary, roads and towns also need to move)
  • Explain how the decisions for selection and generalization are made with regard to symbolization in mapping

  • Discuss Monte Carlo simulation use in GIS&T
  • Discuss effective scientific use of supervisory genetic algorithms with agent-based simulation models
  • Describe how supervisory search and optimization methods can be used to analyze key characteristics of initial conditions and results and to optimize results based on systematic targeted search through the parameter and random seed spaces
GS-16 - Social critiques
  • Explain the argument that, throughout history, maps have been used to depict social relations
  • Explain the argument that GIS is “socially constructed”
  • Describe the use of GIS from a political ecology point of view (e.g., consider the use of GIS for resource identification, conservation, and allocation by an NGO in Sub-Saharan Africa)
  • Defend or refute the contention that critical studies have an identifiable influence on the development of the information society in general and GIScience in particular
