Hello,
I'm trying to read some (Geo)Tiff files with GeoTools, but I get an
error. My code is simple:
File file = new File("C:\\test\\recorte_lceugr.tif");
GeoTiffFormat gtf = new GeoTiffFormat();
GridCoverageReader reader = gtf.getReader(file);
But I get an exception in the third line.
If the TIFF was generated with gvSIG, I get the following exception:
java.lang.IllegalArgumentException: GeoKey directory does not exist

If the TIFF was generated with ArcGIS, then I get:

In this second case (ArcGIS), the problem might be that they are not
real GeoTiff files, as pointed by Niels Hoffmann in [1]. I'm not an
expert on the topic, so I can't be sure.
Anyway, I am able to read these TIFFs with uDig 1.1.1, so I guess that
GeoTools is able to read them, and then the problem should be in my
code or my runtime configuration.
Any idea?
