public static class TransverseMercator.Provider_SouthOrientated
extends TransverseMercator.Provider

The MathTransformProvider for a South Orientated TransverseMercator projection (EPSG code 9808). Note that at the contrary of what this class name suggest, the projected coordinates are still increasing toward North. This is because all MapProjections must complies with standard axis orientations. The real axis flip is performed by the CRS framework outside this package. See "Axis units and orientation" in package description for details.

The usual Transverse Mercator formulas are:

The Transverse Mercator South Orientated Projection formulas are:

Where the px and py terms are the same in both cases. Transforms created by this provider actually computes (easting,northing) = (-westing,-southing). This is equivalent to a TransverseMercator projection with falseEasting and falseNorthing sign reverted. This operation is implemented as a concatenation of a North-orientated transverse mercator projection with an affine transform for (false easting,false northing) correction.
