Examples of ucar.nc2.dt.TrajectoryObsDataset

ucar.nc2.iosp.IOServiceProvider
A collection of TrajectoryObsDatatype. To open a data file as a TrajectoryObsDataset and access the trajectories it contains use TrajectoryObsDatasetFactory.open() and TrajectoryObsDataset.getTrajectories(), for example:
```
 TrajectoryObsDataset trajDs = TrajectoryObsDatasetFactory.open (uriString); for ( Iterator it = trajDs.getTrajectories().iterator(); it.hasNext(); ) { TrajectoryObsDatatype traj = (TrajectoryObsDatatype) it.next(); } 
```
