Hi John
Thank for your answer. Which of the different trajectory representations does ToolsUI support?

The latest version (4.2) supports all the variants in the CF proposal link I 
sent.


Regards
Kjell R

    Hi all
    I am considering using netcdf-java to write large amount of ship
    track data but I am not sure how to do it "correctly" with
    netcdf-java so that other programs that support multi trajectories
    can use the data i am writing.  Does anyone have a recipe or code
    samples how this should be done?
    I have also discovered that trajectories is missing in toolsUI4.1
    but is present in 4.0. Any reason why this is removed?

    Best Regards
    Kjell Røang

    Hi Kjell:

    The "point obs" convention, now called the "discrete sampling"
    convention, which includes ship tracks, has taken 42 zillion years
    to complete. The latest iteration is at

    https://cf-pcmdi.llnl.gov/trac/wiki/PointObservationConventions

    but its still not been approved as a final CF standard. Any feedback
    on it is appreciated, and ill do what i can to wrap it up.

    ToolsUI 4.2 has consolidated these point obs files under the
    FeatureTypes/PointFeature tab. It should open trajectory files as
    the old 4.0 trajectory tab used to.

    Regards,
    John
