Sorry, the problem can only be reproduced when I don't specify the
GeoTiffFormat.RETAIN_AXES_ORDER parameter (or I set it to false).
Using GeoTiffFormat.RETAIN_AXES_ORDER is good enough to have a proper
output.
AbstractGridFormat format = GridFormatFinder
.findFormat("/tmp/spain.tiff");
AbstractGridCoverage2DReader reader = format
.getReader("/tmp/spain.tiff");
GridCoverage2D gc = reader.read(new GeneralParameterValue[0]);
System.out.println(gc.getEnvelope());
GeoTiffWriteParams params = new GeoTiffWriteParams();
ParameterValue<GeoToolsWriteParams> value =
GeoTiffFormat.GEOTOOLS_WRITE_PARAMS
.createValue();
value.setValue(params);
GeoTiffWriter writer = new GeoTiffWriter(new File("/tmp/spain2.tiff"));
writer.write(gc, new GeneralParameterValue[] { value });
writer.dispose();
AbstractGridCoverage2DReader reader2 = format
.getReader("/tmp/spain2.tiff");
GridCoverage2D gc2 = reader2.read(new GeneralParameterValue[0]);
System.out.println(gc2.getEnvelope());
