<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.

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

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

</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.
