Hello list,
now that I've solved my problems *reading* big raster data, I'm also
trying to *write* them.
I've written some testing code:
CoordinateReferenceSystem crs = CRS.decode(crsString);
Envelope envelope = new Envelope2D(crs, 0, 0, 60000, 60000);
Raster m_Raster =
RasterFactory.createBandedRaster(DataBuffer.TYPE_FLOAT,
60000, 60000, 1, null);
GridCoverageFactory factory =
CoverageFactoryFinder.getGridCoverageFactory(null);
GridCoverage2D gc = factory.create("bigtif",
(WritableRaster)m_Raster, envelope,
null, null, null, null, null);
AbstractGridCoverageWriter writer = new GeoTiffWriter(m_sFilename);
writer.write(gc.geophysics(true), null);
writer.dispose();
However, the method createBandedRaster fails (as I was expecting...):
java.lang.IllegalArgumentException: Size of array must be smaller
than Integer.MAX_VALUE.
at javax.media.jai.RasterFactory.createBandedRaster(RasterFactory.java:307)
Is there a better way to achieve this?
Regards,
César
