4.9.9 Converting a Trajectory in StudioView
Trajectories can be captured in different formats, depending on how they have been generated
and/or what their intended use is. GSG can read
.nmea
,
.traj
, or
.tle
files.
To learn more about …
.nmea
trajectories, see "Creating a Trajectory in StudioView" on page 123.
.traj
files, see "Creating an RSG Trajectory with StudioView" on page 133.
.tle
files, see "Trajectory Two-Line Element Format (TLE)" on page 349.
The conversion of trajectories can become necessary e.g., if a trajectory had been created by
…
… recording it using a GNSS receiver
… using third-party software e.g., Google Earth
… manually entering it into an Excel spreadsheet
… using other means to generate trajectories.
However, it may also be required to change or add certain settings to an .nmea trajectory
e.g., to smoothen, interpolate or equalize its data. This also can be accomplished with the Tra
jectory Editor, see under "Converting a Trajectory in StudioView" above.
StudioView's Trajectory Converter can convert the following input and output file formats:
.nmea
.csv
.gpx
.kml
.kmz
Note: Note that the .csv format represents StudioView waypoints table from the
Trajectory Editor and therefore has the same fields. Working with .csv files, Stu
dioView assumes that for each waypoint the .csv file will have four values: Lat
itude, Longitude, Speed and Altitude.
R e a l i s t i c T r a j e c t o r i e s
Trajectories should always realistically reflect the dynamic capabilities of the type of vehicle in
motion e.g., car, aircraft, ship. To this end, Spectracom recommends using ‘smooth’ methods to
describe the movements, i.e. changes in acceleration, heading or altitude should be gradual, not sud
den or ‘hard’.
