[gdal-dev] GeoEye-1 NITF - Warning 1: Image with 11 bits per sample will not be interpreted properly

[Gong, Shawn (Contractor)]

hi list,

I found help clues to build libecwj2 on Windows. 
The missing winhttp.h can be found in Microsoft Platform SDK for Windows
Server 2003 SP1. But on Microsoft site, this has been superceded by the
Windows SDK for Windows Server 2008 and .NET Framework 3.5. 
I found the original file at
http://download.cnet.com/Windows-Server-2003-SP1-Platform-SDK-ISO-Instal
l/3000-2070_4-10731571.html
Installed it and followed the instructions on
http://lists.maptools.org/pipermail/fwtools/2008-April/001213.html to
set the Include and Library Files.
Successfully built libecwj2 and added it to gdal (stable branch
2009-08-03).  "gdalinfo --format ecw" also works.

However when I tried to open GeoEye-1 NITF, I got "Warning 1: Image with
11 bits per sample will not be interpreted properly".
There are two sub-datasets in NITF (please see the gdalinfo at the end).
If I open the 2nd sub-dataset, the data show only 73 pixels and 220
lines; digital numbers are either 0 or 255. If I open the 1st
sub-dataset, python.exe crashed at ncsjpcbuffer.cpp's 
		CNCSJPCBuffer::~CNCSJPCBuffer()
		{
			Free();
		}
The OpenEV from FWTools2.3.0 behaves the same.

I found this Gdal-dev post:
http://lists.osgeo.org/pipermail/gdal-dev/2007-December/015139.html
Does that mean the 11-bit NITF data will be corrupted that I cannot read
them using Gdal?
I can view GeoEye-1 NITF images using PCI Geomatica.

BTW, I tried to build the nitfdump utility 
"nmake /f makefile.vc nitfdump.exe" 
/out:nitfdump.exe
nitfdump.obj
nitffile.obj
nitfimage.obj
mgrs.obj
nitfaridpcm.obj
nitfbilevel.obj
rpftocfile.obj
..\gtiff\tifvsi.obj

Stop.

Shawn
