java.lang.Object
A factory for grid coverage objects. This factory expects various combinaisons of the following informations:
String objects (CaselessStringKey are accepted as well), while
values may be any Object.The coordinate reference system is inferred from the supplied envelope or grid geometry parameters. If those parameters do not have CRS information, then this factory fallback on a default CRS.
Every methods will ultimately delegate their work to a master
create variant. Developpers can override this method if they
want to intercept the creation of all GridCoverage2D objects in this factory.

This convenience constructor assumes that axis order in the supplied image matches exactly axis order in the supplied envelope. In other words, in the usual case where axis order in the image is (column, row), then the envelope should probably have a (longitude, latitude) or (easting, northing) axis order.
An exception to the above rule applies for CRS using exactly the following axis order:
(NORTH|SOUTH,
EAST|WEST).
An example of such CRS is . This convenience constructor will
interchange automatically the (y,x) axis for such CRS.
If more control on axis order and direction reversal is wanted, use the constructor variant expecting an explicit transform.
