Hi everyone,
I have created a DefaultDerivedCRS that is a rotation of a ProjectedCRS (called
selectedCRS) like this:
> CoordinateReferenceSystem transformedCRS = selectedCRS;
>
> if (getAngleRadians() != 0.0) {
> // Create the rotation transform
> final AffineTransform rotation = new AffineTransform();
> rotation.rotate(getAngleRadians(), getRotationProjCenter().x,
> getRotationProjCenter().y);
>
> // Creates the math transform
> final MathTransform transform = ProjectiveTransform.create(rotation);
>
> // Sets the new CRS name
> String crsName = selectedCRS.getName().toString();
> if (getAngleRadians() != 0) {
> final DecimalFormat formatter = new DecimalFormat("#.##");
> final String rotationText =
> formatter.format(Math.toDegrees(getAngleRadians()));
> crsName += " / Rotation: " + rotationText + "°";
> }
>
> // Rotates the CRS
> transformedCRS = new DefaultDerivedCRS(crsName, selectedCRS, transform,
> selectedCRS.getCoordinateSystem());
My problem is that this method is expected to return a ProjectedCRS and if I
simply cast the DefaultDerivedCRS to ProjectedCRS, I get a ClassCastException.
How can I create such a rotated ProjectedCRS from another ProjectedCRS ?
Kind regards,
Ben
