    Convert geocentric coordinates to WGS 84 geodesic coordinates

    Supported in: Batch, Streaming

    Converts geocentric cartesian coordinates to geodesic polar coordinates. Altitude is defined as height-above-ellipsoid. If any coordinates are null, the output will be null.

    Expression categories: Geospatial

    Declared arguments

    • X coordinate - X coordinate in the source coordinate system.
      Expression<Numeric>
    • Y coordinate - Y coordinate in the source coordinate system.
      Expression<Numeric>
    • Z coordinate - Z coordinate in the source coordinate system.
      Expression<Numeric>

    Output type: GeoPoint with altitude
