Landsat Image weirdness - IDL off topic [message #65694]

Hi all,

Not too sure where to ask this question... hopefully someone here will know!

Ok, I have downloaded a Landsat 7 ETM+ image from USGS (by the way,
their new service, with free historical images is awesome!!)

... but it doesn't look as I hoped it would.. have a look here:
http://www.environmentalmodelers.com/WP/sat_img_problem.gif

Basically, I have, perpendicular to the fly path, some black lines.
These lines are not present along the central line of the image, and the
further you are from this center line, the wider are the black lines.

Also, on the edge of the image, I can see some data extensions, which
surprises me even more!

So, is there anything I can do about this? (I guess it is not an Endian
problem as the rest of the image looks good, it's not a data type
problem either, not a band interleave pb as it is a single band)

Thanks a lot!
Jean
