[gdal-dev] Can't read NITF image

Hi!

I am trying to access an .ntf image.

gdalinfo /Some_Path/03APR13WV010500013APR03073140-
P1BS-500060446050_03_P002.ntf -noct -nomd -nogcp -sd 1

ERROR 4: `/vsisubfile/3884_478612158,/Some_Path/03APR13WV010500013APR03073140-
P1BS-500060446050_03_P002.ntf' not recognised as a supported file format.

ERROR 1: Unable to open JPEG2000 image within NITF file.
No JPEG2000 capable driver (JP2KAK, JP2ECW, JP2MRSID, JP2OPENJPEG, etc...) is
available.
You can define the NITF_OPEN_UNDERLYING_DS configuration option to NO, in order
to just get the metadata.
gdalinfo failed - unable to open '/Some_Path/03APR13WV010500013APR03073140-
P1BS-500060446050_03_P002.ntf'.

Indeed,

gdalinfo --formats | grep JPEG
JPEG (rwv): JPEG JFIF

there is no JPEG2000 support (working in Funtoo, gdal installed via portage, I
think this: <http://gpo.zugaina.org/AJAX/Ebuild/2502482/View>)

Setting

export NITF_OPEN_UNDERLYING_DS=NO

let's me read the metadata.

Is this a *generic* problem or else, if I compile --with-jasper support will
allow for reading this image? And, subsequently, import via r.in.gdal in
GRASS-GIS?

Thank you, Nikos

This is a problem you'll run into each time you will open a NITF image whose
imagery is compressed as a JPEG2000 codestream. Compiling --with-jasper might
help, but if your image is big, it might not work since jasper reads the whole
image into memory. If you run into this memory problem, you might use OpenJPEG
2 instead (provided you use GDAL 1.10), or else one of the proprietary
implementation.

If gdalinfo can open it, then it should work with r.in.gdal.

O-K, looks much better now:

Question: how can I tell which driver is used? Just empirically, e.g. Jasper
precedes OpenJPEG2? Oh well, I'll have to search in the manuals I guess...

> or else one of the proprietary implementation.

I've been through posts in the list and reading details in

<http://trac.osgeo.org/gdal/wiki/ECW>,
<http://trac.osgeo.org/gdal/wiki/JasPer>,
<http://trac.osgeo.org/gdal/wiki/JP2KAK>,
<http://trac.osgeo.org/gdal/wiki/MrSID>

So, what's the take-home message for an average QGIS user for example? I am
not critisising -- just being curious, honestly.

Milles Mercis Even,
Nikos

gdalinfo --formats | grep JP

JPEG (rwv): JPEG JFIF
JP2OpenJPEG (rwv): JPEG-2000 driver based on OpenJPEG library
JPEG2000 (rwv): JPEG-2000 part 1 (ISO/IEC 15444-1)

According to <http://trac.osgeo.org/gdal/wiki/ConfigOptions>, GDAL_SKIP:

export GDAL_SKIP="JPEG JPEG2000" && gdalinfo --formats | grep JP

JP2OpenJPEG (rwv): JPEG-2000 driver based on OpenJPEG library

Nice! Thanks, Nikos

Re: Can't read NITF image

All works fine. A quick one-liner example to get the image(s):

for INPUT in `gdalinfo 03APR13WV010500013APR03073140-
P1BS-500060446050_03_P002.ntf | grep SUBDATASET_ | grep NAME | cut -d":" -f3`;
do gdalwarp -s_srs 'epsg:4326' -t_srs 'epsg:4326' "${INPUT}" "${INPUT}.tif";
done

Are there smarter ways to do that?

Thanks, Nikos
