I've been trying to use the gdalinfo application to examine a number
of FITS files that I've grabbed off the net. I've run into problems
with both the precompiled/linked version of gdalinfo that comes with
FWTOOLS.2.0.6, and with a copy I built myself from GDAL 1.7.2 source
code and the cfitsio library. I'm running Linux (Fedora Core 13,
Kernal 2.6) on a 32 bit Intel platform. It's not that I'm interested
so much in the output of gdalinfo, but I wanted to verify that the
underlying GDAL library could handle FITS before using it in my own
application.
Most FITS files I tried caused gdalinfo to die with a segmentation
fault. For example, the following files caused segmentation faults:
http://fits.gsfc.nasa.gov/nrao_data/tests/ftt4b/file013.fits
http://fits.gsfc.nasa.gov/nrao_data/samples/wcs/m82opt.fits
The remaining files I tried caused more graceful failures,
represented by the message below.
ERROR 1: FITS file /opt/data/fits/ngc6503.fits does not have 2 or 3
dimensions.
gdalinfo failed - unable to open '/opt/data/fits/ngc6503.fits'.
File from http://fits.gsfc.nasa.gov/nrao_data/samples/cubes/ngc6503.fits
I was able to view these FITS file using SAOImage DS9. indicating
that the files were not corrupt.
Has anybody tested GDAL against FITS files recently?
Thank you,
Eric.
