Projection.initialize() method

The initialization method defined in the base class Projection is not called in this case.
Clearly, classes that extend the base projection class are required to call this method to initialize the projection parameters - by my understanding of the codes.

However, many classes extending the Projection class (like LandsatProjection class) do not provide the default constructor and most likely the initialize() method is never called in such cases.
Are the users supposed to call the initialize() method? If not how about consider making it protected method?

Start by reading the base Projection class and the LandsatProjection subclass, then trace how projection instances are constructed and whether initialize() is invoked. Compare the behavior across other Projection subclasses before deciding whether initialization is an internal lifecycle concern or a caller responsibility. Done means the initialization contract is explicit and consistently enforced or documented.
