[gdal-dev] GDAL: How to create one NITF image from CIB CD

[Martin Chapman]

Carol,

If you write code the way to go about mosaicing all rpf frame files into one
image would be to create a GDAL MEM dataset that is the width and height of
an entire RPF Boundary.  Then loop through each Frame file in the Boundary,
open up each Frame file with the GDAL NITF driver and copy the bytes from
the NITF file into the correct tile location in the MEM grid.  Then save the
GDAL MEM file out to the file format of your choice.  

Also, I think www.ossim.org will have the utilities you need to do this
already built.  Look at OrthoIgen.exe.

Martin

Hi.  
Thank you for getting back to me on this!
Yes, I am using the 1.6.0 version of GDAL.  

I did what you suggested and it gives me a bus error when I run the
gdalinfo command on the a.toc file.  Do you recall what the problems
were with the CIB data that you heard about?  I have a 1 meter, 5 meter
and 10 meter data sets that I tried and I got a bus error on all of
them.  Any other ideas?

Thanks,

Carol

Selon "Rydzak, Carol-P28503" <Carol.Rydzak at gdc4s.com>:

I assume you are using a recent enough GDAL version (>= 1.5.0) that has
the RPFTOC driver. If so, gdalinfo on the a.toc should return a list of
subdatasets (at least one). You can then select one and translate it to
a GeoTIFF. It will mosaic all the underlying NITF tiles. See
http://gdal.org/frmt_various.html#RPFTOC for more info.

Someone recently reported problems with CIB but I've not heard any news
since then. The driver was tested against CADRG datasets but should
theoritically work with CIB too.
