Get the centre of the track

[Dovelet1]

Dear all，

Is there some way to get a central drift track as shown below when using the Leeway model？

Thanks！

Hi,

Yes, there is a method center_of_gravity which will provide the center positions as well as the spatial variance: https://opendrift.github.io/_modules/opendrift/models/basemodel.html#OpenDriftSimulation.center_of_gravity

Note that we have recently created a new package TrajAn for the analysis of output from OpenDrift, as well as any other model or measurements that follow the netCDF convention on trajectories. With TrajAn, you can do this more easily and transparently using Xarray syntax: https://opendrift.github.io/trajan/gallery/example_opendrift.html#sphx-glr-gallery-example-opendrift-py

TrajAn does not have very much funtionality yet, but may still be worth testing out.

Thanks for the fast reply.As you suggested, I have solved the problem using the method center_of_gravity. Next I will use TrajAnd to analyse my results. Thanks again for your help!
