CullMaskStep.define_critical_land_transects(gf)

Define transects along which land must be present (e.g. to block ocean flow). This method can be overridden in subclasses to either add additional transects or to replace the transects defined in the base class. Use the merge() method to add transects to the feature collection.

Parameters:

gf (geometric_features.GeometricFeatures) – The geometric features from which to get the transects

Returns:

fc_crit_land_transects (geometric_features.FeatureCollection) – The transects that must be land
