Instance Method Details

#coordinates ⇒ Object

A single tuple consisting of floating point values for longitude, latitude, and altitude (in that order). Longitude and latitude values are in degrees, where:

  • longitude >= -180 and <= 180

  • latitude >= -90 and <= 90

  • altitude values (optional) are in meters above sea level
