public static Datum create(int spheroid)

Creates a datum instance based on a spheroid code. Since Datum instances are immutable, the same instance is returned each time for the same spheroid code.

Parameters:

spheroid - the spheroid code for the datum.

Returns:

the datum object, or null if the specified spheroid has no valid datum.
