Hi,
I am writing some geotiff and would like then open them using GT !
My writing operation is thi s:
GridCoverageFactory gcf = new GridCoverageFactory();
Color[][] colors = new Color[][] {{Color.WHITE, color}};
GridCoverage2D gc = gcf.create("Horizon Coverage", rasterCoverage,
this.rasterEnvelope,null,null,null,colors,null);
// The Format used to write a geotiff file.
final GeoTiffFormat format = new GeoTiffFormat();
// The parameters used to write a geotiff file.
final GeoTiffWriteParams wp = new GeoTiffWriteParams();
// No compression -> never mind the size of pictures, we must go fast
wp.setCompressionMode(GeoTiffWriteParams.MODE_DISABLED);
// We keep the tile size
wp.setTilingMode(GeoToolsWriteParams.MODE_DEFAULT);
final ParameterValueGroup paramWrite = format.getWriteParameters();
paramWrite.parameter(AbstractGridFormat.GEOTOOLS_WRITE_PARAMS.getName().toString()).setValue(wp);
File outFile = new
File(getCoveragesFolder(true).getPath()+File.separator+"coverage.TIF");
GeoTiffWriter gtw = (GeoTiffWriter)format.getWriter(outFile);
gtw.write(gc,(GeneralParameterValue[])paramWrite.values().toArray(new
GeneralParameterValue[1]));
When I have done this, I want to read this geotiff newly created, like this
:
Hints hints = new Hints(Hints.FORCE_LONGITUDE_FIRST_AXIS_ORDER,
Boolean.TRUE);
GeoTiffReader reader = new GeoTiffReader(outFile, hints);
MapLayer coveragelayer = new DefaultMapLayer(reader.read(null),
getCoverageLayerStyle());
coveragelayer.setTitle("_");
context.addLayer(coveragelayer);
But then , I got this message :
org.opengis.referencing.operation.OperationNotFoundException: Les paramètres
de Bursa Wolf sont requis.

So I tried to put in the layer the GridCoverage directly instead of the
GeotiffReader,
and then, i got this message :
java.lang.AssertionError: GeneralEnvelope[(-40.72106049886832,

I cant fix the problem...
I can open the created geotiff in QGis with no problem, and can find this in
the Properties/Metadatas :
Driver:
GTiff
GeoTIFF
