Target entity: World Geodetic System 1984
Context triple: [Spinnaker Island, hasCoordinateSystem, World Geodetic System 1984]
  • A. WGS84 chosen
    WGS84 is the global geodetic reference system and standard coordinate framework used for GPS and most modern mapping applications.
  • B. GRS80
    GRS80 is a geodetic reference ellipsoid defined in 1980 that serves as a standard mathematical model of the Earth's shape for modern mapping and surveying systems.
  • C. North American Datum of 1983
    North American Datum of 1983 is a geodetic reference system used across North America to define precise locations on the Earth's surface for mapping, surveying, and navigation.
  • D. Global Geodetic Observing System
    The Global Geodetic Observing System is an international framework that integrates various space-geodetic and ground-based measurement techniques to monitor and understand changes in the Earth’s shape, rotation, and gravity field.
  • E. International Terrestrial Reference System
    The International Terrestrial Reference System is a globally standardized, Earth-centered coordinate framework used for precise positioning, navigation, and geodetic measurements.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
