MapProjectionptDst. This method
returns longitude as x values in the range [-PI..PI] and latitude as
y values in the range [-PI/2..PI/2]. It will be checked by the caller, so
this method doesn't need to performs this check.
Input coordinates have the MapProjection.falseEasting and MapProjection.falseNorthing removed and
are divided by MapProjection.globalScale before this method is invoked. After this method is
invoked, the MapProjection.centralMeridian is added to the x results in ptDst.
This means that projections that implement this method are performed on an ellipse (or
sphere) with a semi-major axis of 1.
In PROJ.4, the same standardization,
described above, is handled by pj_inv.c. Therefore when porting projections from
PROJ.4, the inverse transform equations can be used directly here with minimal change. In the
equations of Snyder, MapProjection.falseEasting, MapProjection.falseNorthing and MapProjection.scaleFactor
are usually not given. When implementing these equations here, you will not need to add the
MapProjection.centralMeridian to the output longitude or remove the MapProjection.semiMajor
(a or R).
