Welcome to DriftMLP’s documentation!¶
driftmlp is a pacakage which gives a measure of separation which represents the ocean currents. The intended use of the package uses the global drifter program data [LC19]. The package can be used with other datasets; however the default parameters will need to be carefully tested.
driftmlp implements a relatively straightforward method described in [OMalleySLJM21]. We use the h3-system from UBER for discretization and provide various plotting and processing methods for this. Our intended uses of the package are:
Use as a better measure of separation than geodesic distance when analysing ocean-borne species.
A method to extract a transitition matrix from the global drifter program data.
Exploratory analysis of ocean currents.
If you’re using this to just extract a transition matrix read the paper to see exactly what transition matrix is created.
