I assume fastdtw's MIT license is compatible with BSD. There's not much code in https://github.com/slaypni/fastdtw so it may be better to add this functionality to MovingPandas directly than to add another dependency that doesn't seem to be under active development. But then again it seems to be Cython ... so not sure what that means for MovingPandas packaging.

Hausdorff distance looks like a quick win: https://docs.scipy.org/doc/scipy/reference/generated/scipy.spatial.distance.directed_hausdorff.html

Hi. are this measurements(DTW ,LCSS ,...) available on movingpandas?
from movingpandas.
So far, none of the above measurements has been implemented in MovingPandas. Do you happen to know a good existing Python implementation?

I've heard of fastdtw python library for measuring similatiry between trajectories, But don't know whether MovingPandas trajectories could be used as an input for this library or not. This library takes two array and a distance method as inputs for measuring similarity.

Potentially even easier: https://shapely.readthedocs.io/en/stable/manual.html#object.hausdorff_distance
from movingpandas.
i use this libraries
- https://github.com/joaofig/discrete-frechet for frechet
- https://github.com/tslearn-team/tslearn for dtw and lcss and
- https://docs.scipy.org/doc/scipy/reference/generated/scipy.spatial.distance.directed_hausdorff.html for hausdroff
hope it helps.

Another potential library: https://github.com/cjekel/similarity_measures
