<waypoints>
<waypointvec-
tor>
Example: Trajectory description files in <positiononly> waypoint format
The following are two examples in <property
waypointformat="positiononly"> format. The examples emphasize on the dif-
ferent formats and explain the used time stamp principle.

Parameter
<noofway-
points>
<attitudecontinu-
ous>
<data>
The <waypointvector data> parameters in the following example are vectors
with size of 3, because of the tag <property
datavectorhastimestamp="no">. Even if a fourth value has been defined, it
would have been ignored.
The time stamp is defined with the tag <property timeresolution="0.05">:
T = 0, T = (2-1)*0.05 = 0.05, and so on, T
1 2
Description
Number of the used waypoints vectors.
Use the parameter to minimize the size of the waypoint without actually
deleting the waypoints
If <attitudecontinuous="no">, the attitude angles to be read are
bounded by 2*PI.
The <attitudecontinuous="yes"> means that they are not boun-
ded.
Description of the trajectory as a list of waypoint vectors.
Coordinates of the waypoint in the format selected by <coordsystem>
●
[time,]longitude,latitude,altitude (geod wgs84)
●
[time,]X,Y,Z (cart ecef)
●
[time,]EAST,NORTH,UPPER (enu)
Depending on the <datavectorhastimestamp>, 3 or 4 values are
evaluated with <property waypointformat="positiononly"/>
Depending on the <property waypointformat>, more information
can be provided. The following is a list of the information appended to the
coordinates of the waypoint mentioned above.
●
<property waypointformat="positiononly">
No additional information
●
<property waypointformat="position_attitude">
yaw/heading,pitch/elevation,roll/bank, e.g.
[time,]longitude,latitude,altitude,yaw,pitch,roll
The vehicle attitude (yaw, pitch and roll) parameters are configured
relative to the local horizon
●
<property
waypointformat="position_velocitymagnitude">
vel, e.g. [time,]X,Y,Z,vel
●
<property
waypointformat="position_velocitymagnitude_attitude">
vel,yaw/heading,pitch/elevation,roll/bank, e.g.
[time,]EAST,NORTH,UPPER,vel,yaw,pitch,roll
●
<property waypointformat="position_velocityvector">
Velocity vector Vx,Vy,Vz, e.g. [time,]X,Y,Z,Vx,Vy,Vz
●
<property
waypointformat="position_velocityvector_attitude">
yaw/heading,pitch/elevation,roll/bank,Vx,Vy,Vz, e.g.
[time,]longitude,latitude,altitude,yaw,pitch,roll,
Vx,Vy,Vz.
Note: If the waypoints are in geod wgs84, velocity vector is assumed in
Cartesian ECEF coordinate system.
