<element name="spherical_coordinates" required="0">
  <element name="surface_model" type="string" default="EARTH_WGS84" required="1">
    <description>
      Name of planetary surface model, used to determine the surface altitude
      at a given latitude and longitude. The default is an ellipsoid model of
      the earth based on the WGS-84 standard. It is used in Gazebo's GPS sensor
      implementation.

  <element name="world_frame_orientation" type="string" default="ENU" required="0">
    <description>
      This field identifies how Gazebo world frame is aligned in Geographical
      sense.  The final Gazebo world frame orientation is obtained by rotating
      a frame aligned with following notation by the field heading_deg (Note
      that heading_deg corresponds to positive yaw rotation in the NED frame,
      so it's inverse specifies positive Z-rotation in ENU or NWU).
      Options are:
        - ENU (East-North-Up)
        - NED (North-East-Down)
        - NWU (North-West-Up)
      For example, world frame specified by setting world_orientation="ENU"
      and heading_deg=-90° is effectively equivalent to NWU with heading of 0°.

  <element name="latitude_deg" type="double" default="0.0" required="1">
    <description>
      Geodetic latitude at origin of gazebo reference frame, specified
      in units of degrees.
    </description>
  </element>

  <element name="longitude_deg" type="double" default="0.0" required="1">
    <description>
      Longitude at origin of gazebo reference frame, specified in units
      of degrees.
    </description>
  </element>

  <element name="elevation" type="double" default="0.0" required="1">
    <description>
      Elevation of origin of gazebo reference frame, specified in meters.
    </description>
  </element>

  <element name="heading_deg" type="double" default="0.0" required="1">
    <description>
      Heading offset of gazebo reference frame, measured as angle between
      Gazebo world frame and the world_frame_orientation type (ENU/NED/NWU).
      Rotations about the downward-vector (e.g. North to East) are positive.
      The direction of rotation is chosen to be consistent with compass
      heading convention (e.g. 0 degrees points North and 90 degrees
      points East, positive rotation indicates counterclockwise rotation
      when viewed from top-down direction).
      The angle is specified in degrees.
