GS-18 - Cultural influences
  • Collaborate effectively with colleagues of differing social backgrounds in developing balanced GIS applications
  • Describe the ways in which the elements of culture (e.g., language, religion, education, traditions) may influence the understanding and use of geographic information
  • Recognize the impact of one’s social background on one’s own geographic worldview and perceptions and how it influences one’s use of GIS
AM-57 - Data conversion
  • Identify the conceptual and practical difficulties associated with data model and format conversion

KE-08 - Data costs
  • Identify potential sources of data (free or commercial) needed for a particular application or enterprise
  • Judge the relative merits of obtaining free data, purchasing data, outsourcing data creation, or producing and managing data in-house for a particular application or enterprise
  • Estimate the cost to collect needed data from primary sources (e.g., remote sensing, GPS)
AM-36 - Data mining approaches
  • Describe how data mining can be used for geospatial intelligence
  • Explain how the analytical reasoning techniques, visual representations, and interaction techniques that make up the domain of visual analytics have a strong spatial component

  • Compare and contrast direct and indirect access search and retrieval methods
KE-18 - Data sharing among public and private agencies, organizations, and individuals
  • Describe formal and informal arrangements that promote geospatial data sharing (e.g., FGDC, ESDI, memoranda of agreements, informal access arrangements, targeted funding support)
