[Gdal-dev] gdaladdo problems on an Mac OS X Panther

[Gross, Dorit (SDRN)]

Hi Frank, 

The original file is a SPOT VGT HDF that was converted into GeoTiff using
gdal_translate. The overviews are added just in the next step. The script was
running before the upgrade of GIS Libs. I tried the script for different SPOT
files after the upgrade but receive now the same error message for all of
them. 

I can provide you an image. Please let me know where it can be uploaded to.

Regards,
Dorit

Dorit,

It *sounds* like the input file may be corrupt in some sense.  Was it
generated with libtiff?  Can you make the original file available for me to
look at?

Best regards,
