Hello again, list.
Just for the record, I could successfully create the ArcGrid reader
using Simone's new code.
Probably, the first JAR file he sent was already correct, but my
runtime environment was taking the old one (I still don't fully
understand why... Andrea suggested that it was a problem with maven
dependences [and probably it was], but this is weird for me as I was
launching my test code from Eclipse, from a Java project which
*didn't* have a pom.xml file, so I didn't expect maven interfering in
the runtime configuration of this project...)
I want to thank Simone for his support and patience.
Now I have another problem... although creating the reader succeeds, I
get a similar error when reading the file.
However, I guess it is not a problem with the driver itself, but
rather a wrong usage of it.
The code comes from Sextante-GeoTools bindings:
ArcGridFormat agf = new ArcGridFormat();
GridCoverageReader reader = agf.getReader(file);
GridCoverage2D gc = (GridCoverage2D) reader.read(null);
PlanarImage img = (PlanarImage) gc.geophysics(true).getRenderedImage();
Raster raster = img.getAsBufferedImage().getRaster();
And then I get:
05-oct-2009 17:20:56 org.geotools.gce.arcgrid.ArcGridReader
getCoordinateReferenceSystem
INFO: Unable to find crs, continuing with default WGS4 CRS
java.lang.IllegalArgumentException: Dimensions (width=59000

at javax.media.jai.PlanarImage.getAsBufferedImage(PlanarImage.java:2546)
at etclusi.tests.gt.TestArcGrid2.main(TestArcGrid2.java:39)
The question is whether
img.getAsBufferedImage().getRaster();
is the right way to access a huge raster, or there are better methods
to perform it.
I know that this is a generic JAI question (nothing Geotools
specifical), but I would really appreciate if someone can point me to
the right solution. A JAI tutorial on this subject would also be
appreciated :-D
We'd like to process huge data sets with Sextante + GeoTools, so I
would really appreciate any clue on this.
Best regards,
César Martínez Izquierdo
