# GeoPositionXYZ

GeoPositionXYZ[{x,y,z}]
represents a position in a Cartesian geocentric coordinate system.

GeoPositionXYZ[{x,y,z},datum]
represents a point referred to the specified datum.

GeoPositionXYZ[{{x1,y1,z1},{x2,y2,z2},},datum]
represents an array of points in a Cartesian geocentric coordinate system.

GeoPositionXYZ[entity]
returns the Cartesian geocentric position of the given geographical entity.

## DetailsDetails

• GeoPositionXYZ uses an Earth-centered, Earth-fixed coordinate system.
• Coordinate values are assumed to be in meters.
• For extended entities, GeoPositionXYZ[entity] uses when possible the position of the geographic center of the entity.
• If no datum is specified, GeoPositionXYZ refers to the International Terrestrial Reference Frame 2000.
• Typical values for datum specifications include "ITRF00", "NAD83CORS96", and "WGS84".
• GeoPositionXYZ[{x,y,z,t}] includes a time t measured in seconds since the beginning of January 1, 1900 in the GMT time zone.
• A GeoPositionXYZ object with no explicit time assumes the current date.
• GeoPositionXYZ[GeoPositionXYZ[{x,y,z},datum1],datum2] converts between datums.
• GeoPositionXYZ[pos] or GeoPositionXYZ[pos,datum] converts from any geographic position type. The following geographic position types can be given: GeoPosition, GeoPositionXYZ, GeoPositionENU, GeoGridPosition.
