is_collapsible

geodetic_engine.geodesy.utils.is_collapsible(operation)

Whether a concatenated operation is a chain of plain Helmert steps.

A cheap structural check. It does not prove the collapse is numerically faithful; only collapse_concatenated() does that.

Parameters:

operation (CoordinateOperation) – The operation to inspect.

Return type:

bool

Returns:

True if every step is a plain Helmert and all steps share one domain.
