TS01G: DYNAMIC DATUMS AND WORKING WITH RESULTANT DATA - FOR BOTH SURVEYORS AND GEOSPATIAL EXPERTS [10563]

Commission: 5
Chair: Dr. Chris Pearson, New Zealand
Rapporteur: Dr. Kevin Ahlgren, United States


3D Datums are the foundation for reference frames – both global and national. Now the 4th dimension is coming into play, and the surveying and geospatial community wants to understand more about how reference frames – of all types – are suited for which applications.

Guiding Questions for Discussions:

• What is the typical response to dynamic datums?
• Are they understood and accepted?
• Will static datums become a thing of the past?
